ABSTRACT — The morphological characteristics of Neohodgsonia mirabilis are reassessed and

illustrated with recent, living specimens. Chromosome number, habitat and distribution are

outlined. The monotypic genus Neohodgsonia is confirmed to belong to the family Marchan-

tiaceae.

RÉSUMÉ — Les caractéristiques morphologiques de Neohodgsonia mirabilis, espèce rare de

l'hémisphére sud, sont réétudiées et illustrées à l'aide d’ échantillons vivants récoltés récemment.

Le nombre chromosomique, l'habitat et la distribution sont précisés. Le genre Neohodgsonia est

monotypique. Son appartenance à la famille des Marchantiaceae est confirmée, Son archégo-

niophore très рагтісшін stipe ramifié et à segments du réceptacle non fusionnés, est expliqué

par une séquence de division plus lente de la cellule apicale qui lui donne naissance.

Neohodgsonia is a monotypic genus. It occurs exclusively in New Zealand

and Tristan da Cunha and is infrequent. Several imprecisions and inaccuracies are

found in former descriptions that could place the genus in several phylogenetic

lineages. Additional information on its morphology was needed for a forthcoming

phylogenetic analysis of the Marchantiales. Recently, collected living samples made

it possible to reassess and illustrate its characteristics, to add data formerly not

included in its diagnosis, and to make a description comparable with that of the

other marchantialean genera.

wide, sinuose, with slightly thickened walls. Scales in two rows, hyaline at thallus

apex, brownish in older parts, rounded or obtuse apically, without appendage,

without oil-cells but with hyaline marginal mucilage papillae becoming brownish on

older scales (fig. 1 : 1-11, fig. 4 : A-C, fig. 6 : A, C-D).

gemmae cups, found on sterile and fertile thalli. Gemmae cups with lobed-ciliate

margins; lobes with a row of 3-5 cells apically and cilia of 1-2 cells; 1-2-celled

papillae at bottom of outer side. Gemmae with a single growing point, overarched by

mucilage hairs. No mucilage hairs at bottom of gemmae cups (fig. 1 : 12-13, fig. 4:

structure than thallus pores, and one layer of large air-cavities with mucilage

papillae ; involucre thin, 1-2-stratose, hyaline, with oil-cells, bivalve, with entire

margins, connate until sporophyte maturity and opening then from near top of segment

towards bottom. Scales along ventral side of stalk and segments hyaline, becoming

later brownish, rounded or obtuse apically, without appendage, some with a single

oil-cell, with mucilage papillae on margins. Archegonial cavity with 4-10 archegonia,

HABITAT — In New Zealand : in montane forests in wetter parts of the country,

at altitudes of between 490 and 1180 m. It is usually found under Nothofagus

menziesii forest but is also found under Nothofagus fusca forest and Weinmannia

racemosa — Metrosideros umbellata forest. Accompanying species are the ferns

Histiopteris incisa, Hypolepis rufobarbata and Polystichum richardii, the mosses

Atrichum androgynum, Wijkia extenuata, Hypnodendron spininervium, Distichophyl-

lum crispulum, Rhizogonium distichum, Ditrichum cylindrocarpum and Campylopus

purpureocaulis, the hepatics Aneura alterniloba and Telaranea gottscheana and the

herb Cardamine debilis. The usual substrate is well drained soil, most often the

mineral soil attached to the root plate of fallen trees. It also occurs on steep banks,

both on mineral and humic soils, in colonies up to one square meter.

DISCUSSION — Neohodgsonia has all characteristics that define the family

Marchantiaceae : a single layer of air-cavities, each with a compound epidermal

pore; terminal, stalked antheridiophores and archegoniophores, the stalk of the

archegoniophore elongating before fertilization of агсћеропіа ; sporophytes pro-

tected by a calyptra, a campanulate pseudoperianth opening irregularly at top, and

an involucre.

The flavonoid pattern of Neohodgsonia, of intermediate complexity (Camp-

bell er al. 1979), shows affinities to Lunularia Adans., Conocephalum Hill and subg.

Marchantia, and places the genus in the Marchantiaceae (including also the genera

Conocephalum and Lunularia for Campbell et al.).

Many of the characteristics of Neohodgsonia are not found in any of the

other genera of the Marchantiales : very large, obliquely oriented air-cavities with

bistratose partitions and mucilage papillae; archegoniophore stalks with well-

developed air-cavities that preserve the generalized form of the thallus, with decurved

margins, median strand of rhizoids, dorsal air-cavities and large ventral scales ; and,

most striking, juxtaposed segments in the archegoniophore, not yet condensed into

a single receptacle, preserving the obviously dichotomous origin of its partitions.

These characteristics were postulated as primitive by Schuster (1992) who thought

the genus to belong, together with Lunularia, to the most primitive forms found in

the suborder Marchantiineae (Marchantiales with stalked receptacles), despite some

advanced features as asexual reproduction by gemmae and small spores.

An explanation for the unusual structure of the archegoniophore in

Neohodgsonia could imply a slower division rate of the apical cell involved in its

development. This cell is located in the primordium of the archegoniophore and

divides after contraction of the primordium at its junction with the thallus in all

representatives of the suborder Marchantiineae (Leitgeb 1881). Its subsequent

divisions, nearly simultaneous in the other Marchantiineae, could Бе delayed and

spaced in time in Neohodgsonia, resulting in receptacles with independent, shortly

stalked segments (Bischler 1987). Whether this character is primitive remains

controversial,

The fully developed archegoniophore in other Marchantiaceae as, for

instance, in Marchantia L. and Preissia Corda, may occasionally have branched

stalks, but such stalks probably originate from two apical cells differentiating close

to each other at thallus apex. A double number of rhizoid furrows in the fused part

of stalk is present, becoming single in each branch (Bischler 1987). Homology with

the stalks in Neohodgsonia is questionable, as the rhizoid furrow in this genus is

single at the stalk bottom and divides only near the branching point.

The phylogenetic position of Neohodgsonia remains controversial. Whether

it is one of the most primitive forms in the Marchantiineae, as stated by Schuster

(1992), or a sister group of Marchantia, close to the most derived genera in the

Marchantiales, remains uncertain.

PYCNOCONIDIAL TYPES AND THEIR PRESENCE

IN CETRARIOID LICHENS

(ASCOMYCOTINA, PARMELIACEAE)

Arne THELL

Department of Systematic Botany, University of Lund

ABSTRACT — The pycnoconidia in about 70 cetrarioid lichen species have been investigated.

Five main types are recognized: bacillariform, bifusiform, citriform, filiform and sublageniform

pyenoconidia. The largest morphological variation is found within the bifusiform and citriform

types. The variation and presence of different types within cetrarioid lichens are described and

RESUME — Les pycnoconidies d’environ 70 lichens cétrarioïdes ont été étudiés. 5 types

principaux de pycnoconidies sont distingués: bacilliforme, bifusiforme, citriforme, filiforme et

sublagéniforme. Les variations morphologiques les plus importantes s'observent à l'intérieur des

types bifusiforme et citriforme. La présence des différents types et de leurs variations dans les

lichens cétrarioides sont décrits et discutés.

INTRODUCTION

The cetrarioid lichens belong to different evolutionary lines (Kärnefelt er al.

1992). Basically these taxa have been characterized by marginally situated apothecia

and pycnidia. In addition, an erect foliose thallus with a dorsiventral structure is also

characteristic for the cetrarioid group (Randlane & Saag 1993). Several separate

genera have recently been described (Brusse & Kärnefelt 1991, Kurokawa & Lai

1991, Kärnefelt et al. 1993, Kärnefelt & Thell 1993, 1994, Mattsson & Lai 1993,

Randlane et al. 1994). Furthermore, a number of cetrarioid species have changed

generic position (Randlane & Saag 1992, Randlane et al. 1995, Thell 1995, Thell et

al. 1995a, b, с). More than twenty cetrarioid genera and species groups are

recognized in modern taxonomy but the affinities of some taxa are still uncertain.

The cetrarioid lichens can be divided into three groups based on characters in asci

and ascospores :

1. Genera with narrowly clavate asci and ellipsoid ascospores: Arctocetraria Kärnef. &

Thell, Cetraria Arch., Cetrariopsis Kurok., Cetreliopsis Lai, Flavocetraria Kärnef. &

Source : MNHN, Paris

248 A. THELL

Thell, Masonhalea Kärnef. and Nephromopsis Müll. Arg. The genus Coelopogon

Brusse & Kärnef. probably is placed here basically оп morphological grounds.

Apothecia and pycnidia have unfortunately not been observed.

IL. Genera with narrowly clavate asci and globose or subglobose ascospores : Ahtiana

Goward, Allocetraria Kurok. & Lai, Esslingeriana Hale & Lai, Tuckermannopsis

Gyelnik and Tuckneraria Randl. & Thell. Several taxa have been transferred to

Tuckermannopsis (Lai 1980, Hale 1987, Kärnefelt et al. 1993). Some of these entities

are obviously not closely related to the type species, Т. ciliaris (Kurokawa 1990,

Mattsson & Lai 1993, Thell 1995, Thell er al. 1995b, с). In this investigation only

taxa with globose or subglobose ascospores distributed mainly in North America and

Five main types of pycnoconidia are recognized within the cetrarioid group:

1. bacillariform, 2. bifusiform, 3. citriform, 4. filiform and 5. sublageniform (Fig. 1).

Vobis (1980) did not mention sublageniform as a main pyenoconidial type but four

of the seven main types described by him are present in cetrarioid lichens. Krog

(1982) includes one more type, unciform, from the parmelioid group, present in the

genus Punctelia. Lindsay (1859) investigated pycnidia and pycnoconidia in the

cetrarioid species known at that time, and many of his observations are still valid.

Pyenoconidia have been found in about 70 of the 120 cetrarioid species

listed by Randlane & Saag (1993) in material from a large number of herbaria.

Pycnidia are unknown in Coelopogon and Cetrariopsis. A list of the pycnoconidial

types within the cetrarioid genera is urgently needed, since the terminology is very

confusing and many alternative conceptions for the same type have been used.

Pycnoconidia have been referred to as conidia, pycnospores, pycnidiospo-

res, spermatia, macroconidia and microconidia (microspores). However, pycnoconi-

dia of two different sizes were known only from three lichen genera until now.

Microconidia are always one-celled and are present in most lichen genera, but in

Lecanactis, Micarea and Porina, macroconidia are also developed, two-celled in

Porina (Henssen & Jahns 1973, Coppins 1983). Macroconidia in contrast to

microconidia serve as vegetative propagules for the fungal part of the lichen.

Furthermore, from the genus Micarea mesoconidia are also reported. These

obviously function as asexual diaspores which is presumably the case also for the

Y Melanelia agnata, M. commixta, M. culbersonii and M. hepatizon.

macroconidia in this genus (Coppins 1983). I have chosen to use the longer word

pycnoconidia instead of conidia in this study mainly for two reasons: The first reason

is that I have frequently used this term in my previous papers. Secondly, I wanted

to stress the functional difference between conidia formed in pycnidia and true

conidia, which are usually not developed in pycnidia and serve as vegetative

propagules. Only microconidia are found in cetrarioid lichens. The fact that

microconidia function as spermatia and can become attached to trichogynes has been

noted many times (Stahl 1877, Baur 1898, Admadjian 1966, Jahns 1970, Honegger

1984 a, b, Culberson et al. 1988). Microconidia have therefore been called spermatia

rather than conidia by some (e. g., Tulasne 1852, Lindsay 1859, 1872, Glück 1899,

Johson 1954, Honegger 1984 a), and the structures in which they are formed have

sometimes been called spermogonia rather than pycnidia (Lindsay 1859, 1872, Glück

1899, Poelt & Petutschnig 1992, Poelt & Nash 1993). Some species that develop

apothecia, however, apparently lack pycnidia (e. g., in the genus Cetrariopsis). Here,

apogamy must be the explanation for fertilization of the ascogon (Moreau & Moreau

1928, Letrouit-Galinou 1973).

PYCNOCONIDIAL TYPES

1. Bacillariform pycnoconidia (including bacillariform, rod shaped, staff

shaped and cylindrical types)

True bacillariform pycnoconidia are very rare іп cetrarioid lichens.

Bacillariform conidia are totally straight and uniform and are called cylindrical or

rod-shaped by some authors. They are characteristic for the monotypic genus

Masonhalea, where they measure about 5 х 0.75-1 um and have blunt ends

(Kárnefelt 1977, Kürnefelt er al. 1992) (Fig. 3). Pycnoconidia of the same shape and

size are rarely also found in Ahtiana рашаша (Thell et al. 19950).

Source : MNHN, Paris

250 A. THELL

In Tuckermannopsis inermis and Т. subalpina, several different types have

been seen (Table 1). In these species, the bacillariform type are 8-10 um long

(Kärnefelt er al. 1993).

Rod-shaped or straight pycnoconidia up to 10 um long have also been

reported from the genera Asahinea and Parmelaria (Culberson & Culberson 1965,

Awasthi 1987). However, in Parmelaria 1 have recognized them as typically citriform

(see below).

2. Bifusiform pyenoconidia

Bifusiform pycnoconidia have two more or less distinct, apical or subapical

swellings (Figs. 4-5). This type is the most common within cetrarioid lichens and is

represented by two different shapes of about the same size (с. 5-7 um), partly

overlapping each other:

a. dumb-bell shaped (biclaviform or bipolar).

b. dise-bar shaped

Dumb-bell shaped pycnoconidia, characterized by strictly apical swellings

and the ends more or less rounded to fusiform, are very common (Fig. 4). All

pycnoconidia found in the genera Flavocetraria, Nephromopsis, Cetreliopsis, Esslin-

geriana, and Tuckneraria are dumb-bell shaped, and they are also characteristic of

Ahtiana, Arctocetraria, Melanelia, Tuckermannopsis, the Cetraria fendleri group, and

many other genera in the Parmeliaceae (Kärnefelt et al. 1992, 1993, 1994, Randlane

et al. 1994, 1995, Thell et al. 1995c).

Typically disc-bar shaped conidia with sharp ends and subapical swellings are

characteristic for the Cetraria californica group but are frequently also seen in

Ahtiana and in the Cetraria fendleri group. This shape is very common within many

parmelioid genera such as the brown Parmeliae (Thell 1995).

3. Citriform pycnoconidia (including fusiform and ellipsoid types)

This type includes all pycnoconidia with the central part broader than the

ends (Figs. 6-8). The width in the central part is about 1-1.5 um in all citriform

руспосопійіа, but they could be divided into three shapes or length classes:

а. citriform: с. 3-5 um long.

b. oblong citriform: c. 5-7 um long.

с. very oblong citriform: с. 8-10 um long.

Typically lemon-shaped, citriform conidia (Fig. 6), 3-5 um long, have been

found only in a few cetrarioid species, Melanelia commixta, Parmelaria thomsonii,

Vulpicida canadensis and V. viridis (Kárnefelt el al 1992, Mattsson & Lai 1993).

PYCNOCONIDIA IN CETRARIOID LICHENS 253

The oblong citriform pycnoconidia in Cetraria were called rod-shaped by

Kärnefelt (1979, 1986) and Kärnefelt et al. (1992). To separate them from clearly

rod-shaped pycnoconidia present in Masonhalea richardsonii, we introduced the term

“oblong citriform" for this pycnoconidial type (Fig. 7). This was done in connection

with the delimitation of the genus Cetraria (Kärnefelt et al. 1993). Oblong citriform

pycnoconidia are rarely present as well in Arctocetraria andrejevii, Ahtiana pallidula

and Melanelia commixta (Table 1).

Very oblong citriform pyenoconidia are characteristic for the monotypic

genus Nimisia (Fig. 8) and they occur rarely in Tuckermannopsis inermis and T.

subalpina (Kärnefelt £ Thell 1993, Kärnefelt et al. 1993).

4. Filiform (thread shaped) pycnoconidia

Filiform pycnoconidia are always longer than 10 um. Within cetrarioid

lichens this type is totally restricted to the genus Allocetraria, where they are 10-22

um long, rather bent and somewhat thicker at one end, i. e. slightly sublageniform

(Fig. 9). Filiform pyenoconidia of the same length also occur in several parmelioid

genera but differ from those in Allocetraria in being straight and rod-shaped (Krog

1982).

5. Sublageniform (bottle-shaped, clavate) pyenoconidia

Sublageniform pycnoconidia, present in several genera that are probably

not closely related. are characterized by one end pointed and one the other end

thickened. At least two types can be recognized, perhaps with different origins.

Plainly bottle-shaped pycnoconidia are characteristic of Platismatia and are also

present in four species of Vulpicida (Fig. 11). Another variant of sublageniform

pycnoconidia is rod-shaped but has only one pointed end (Fig. 10). Such

pycnoconidia are characteristic for the genus Cetrariella and are rarely observed in

Tuckermannopsis inermis and T. subalpina (Kárnefelt et al 1993).

DISCUSSION AND CONCLUSIONS

There is often a clear correlation between the pycnoconidial type and other

characters used for generic delimitation within cetrarioid lichens. Good examples are

the related genera Cetrelia, with bifusiform pycnoconidia, and Platismatia, with

pycnoconidia of the sublageniform type (Krog 1982). The well delimited genus

Allocetraria is characterized by a unique type of filiform pycnoconidia (Thell ег al.

1995b). Disc-bar shaped pycnoconidia are characteristic for the Cetraria californica

group and are also present in the presumably related genera Cornicularia,

Nodobryoria, and Pseudephebe (Fig. 5). Four of the five cetrarioid genera with

globose or subglobose ascospores, i. е. Ahtiana, Esslingeriana, Tuckermannopsis and

Tuckneraria are characterized by dumb-bell shaped pyenoconidia (Fig. 4). The two

monotypic genera Masonhalea and Nimisia both have unique pycnoconidial types

(Figs. 3, 8).

Sometimes, however, pycnoconidial morphology seems to be rather

variable, In the presumed monophyletic genera Ahtiana and Vulpicida, two or more

different pyenoconidial types have been observed, even in the same pycnidium (Fig.

2). True citriform pycnoconidia are found in three not so closely related cetrarioid

genera. This is presumably an example of convergent evolution. Several intermediate

forms between bifusiform and citriform pycnoconidia are observed in the North

American material of Melanelia commixta (Thell 1995). The citriform pycnoconidia

in Vulpicida canadensis and V. viridis may have evolved from sublageniform (bottle-

shaped) pycnoconidia present in all other Vulpicida-species by loosing the bottleneck

(Figs. 6, 11). The third genus with this pyenoconidial type, Parmelaria seems to have

an isolated position within cetrarioid genera (Awasthi 1987). Pycnidial and

pycnoconidial characters are still not being included enough in modern classifications

within the Parmeliaceae. For two species in Allocetraria, A. globulans (Nyl.) Thell &

Randi. and A. oakesiana (Tuck.) Thell & Randl., the filiform pycnoconidial shape

solved the systematic position (Thell er al. 1995b). These two species were earlier

included in Cetraria or Tuckermannopsis. Unfortunately, some cetrarioid genera and

species lack pycnidia as well as apothecia. It is sometimes difficult to classify such

species in a phylogenetically meaningful way since morphology and cortex anatomy

are often variable, and chemistry often adds too little information.

ABSTRACT — Buellia vouauxii Calatayud & Ваггепо sp. nov. is described from Las Cañadas

del Teide National Park (Tenerife, Canary Islands). The new lichenicolous fungus, which is a

commensal of Rhizoplaca melanophthalma (Ramond) Leuckert & Poelt., is discussed in relation

to other Buellia species.

Key WORDS : lichenicolous fungi, lichens, Canary Islands, Buellia.

INTRODUCTION

In 1911, Pitard & Harmand published a paper entitled “ Contribution à

l'étude des lichens des Îles Canaries” (Pitard 4 Harmand 1911). This study

considerably increased the number of species known from the Canarian Archipelago,

and many new taxa were described. At the end of this contribution, a list of 13

non-lichenized, lichenicolous species, identified by L. Vouaux, was added. Since then,

records of some lichenicolous fungi from this territory have been reported

sporadically (e.g. Vouaux 1912-1914, Hawksworth 1982); those previous to 1989

have been picked up in Clauzade ег al. (1989). Other more recent finds are included

in Santesson (1994a, 1994b) and in Calatayud et al. (1995).

During the course of a study on some lichens and lichenicolous fungi from

Las Cañadas del Teide National Park (Tenerife), a commensalistic Buellia species

growing on Rhizoplaca melanophthalma was examined. Its particular life strategy, in

combination with its anatomical characters put in evidence that it was an

undescribed taxon. This paper deals with the description of that species, named

Buellia vouauxii in honour of 1. Vouaux, for his earlier contribution to our

knowledge of lichenicolous fungi from the Canary Islands.

METHODS

The material was examined with an Olympus SZ dissecting microscope and

an Olympus BH-2 light microscope, provided with phase contrast. Microphotogra-

phs were taken on AGFAPAN 100 film. The temporary erythrosin mountant was

used for the study of the conidiomatal structures. The exciple and ascospore types

follow Scheidegger (1993). The typology of the conidiomatal structures is in

accordance with that proposed by Vobis & Hawksworth (1981).

Ecology and distribution : The new species is known only from the type

locality, where the host lichen, Rhizoplaca melanopththalma, was quite abundant,

growing together with Rhizoplaca chrysoleuca (Sm.) Zopf. This locality is at more

than 2100 m of altitude, in Las Cañadas del Teide National Park, close to the natural

monument called El dedo del Guanche. The material was collected on almost vertical

probably undescribed Cercidospora species occurring on Rh. chrysoleuca, and two

Arthonia species, Arthonia sp. on Rh. melanophthalma, and Arthonia glaucomaria

(NyL) Nyl. on Lecanora rupicola (L.) Zahlbr., were also found in this locality.

Buellia youauxii can be considered as a commensalistic fungus, because it

enters into a stable relationship with its host, not producing discolourations nor

malformations.

DISCUSSION

The genus Buellia is one of the richest in the Physciaceae, including ca. 400

species (Hawksworth ег al. 1983). It has a cosmopolitan distribution and is still very

poorly known in many parts of the world.

Most of the species of this genus are autonomous, but parasitism is not

unusual in this group (Scheidegger 1993). Modern descriptions and keys for most of

the lichenicolous species are provided by Hafellner (1979), Clauzade et al. (1989) and

Scheidegger (1993). Many of these species are parasites only at initial stages of

development, later developing their own thallus and becoming autonomous (e.g.

Buellia sequax (Nyl.) Zahlbr., Buellia uberior Anzi). Some others, also lichenized (but

normally with a quite small thallus), are parasites during their entire life cycle (e.g.

B. imshaugii Haf., B. miriquidica Scheidegger). Until the discovery of B. vouauxii, the

only non-lichenized species of Buellia known was B. adjuncta Th. Fr., a commensal

of Lecanora straminea Wahlenb. ex Ach. (Hafellner 1979, Santesson 1984) and

Rinodina olivaceobrunnea Dodge & Baker (Alstrup & Hawksworth 1990). In addition

to their occurrence on different host species, B. vouauxii and B. adjuncta differ in

several characters (tab. 1). The apothecia of B. adjuncta are very characteristic : they

are only up to 0.5 mm wide and, except the oldest, are typically concave and have

a thick proper margin (Hafellner & Poelt 1976). Those of B. vouauxii are bigger, up

to 1 mm in diam, flat or convex, and the proper margin is thin or almost

inconspicuous. The size of asci, ascospores and hymenium also differ in both species,

being larger іп В. vouauxii. A stronger ramification of the paraphyses has also been

noted in the new species when it is compared with B. adjuncta.

Since several species formerly referred to the genus Karschia have been

transferred to the genus Buellia (Hafellner 1979), it was initially suspected that

Karschia laeta Gerber, a lichenicolous fungus reported on R. chrysoleuca, might be

conspecific with В. vouauxii. The type of K. laeta is lost (Hafellner 1979), but

according to a description given in Trotter (1972 : 477), this species has hyaline

ascospores, and only up to 10.5 рт large. Considering that description, it seems

obvious that K. laeta is not a species of Buellia. The almost globose apothecia, small

and broad asci, and hyaline, 1-septate ascospores, with cells of different sizes, rather

suggest an Arthonia species.

INTRODUCTION

The biennial summer field meeting of the “Bryologische en Lichenologische

Werkgroep der KNNV (the Dutch Bryological and Lichenological Working group),

was held from 20 — 30 July 1992, based, at Ste-Engrâce, 50 km SW of Pau

(Pyrénées-Atlantiques, France). A group of five lichenologists collected с. 2500

samples: the most interesting records which were identified, are presented in the list

below. Descriptive accounts of the localities visited and a complete species list will

be published elsewhere.

Except for the last decade, papers dealing with the lichen flora of the

western Pyrenees are extremely few. A list of more than 800 taxa, with mostly French

collections are given by Vivant (1988). The Spanish part of the western Pyrenees has

been investigated more intensely since 1986. The most comprehensive treatment is

that by Etayo (1989). In the last few years, several lichenologists from Great Britain,

Belgium, Luxemburg, France, Germany and Austria have visited the western

Pyrenees. Some of their observations have been published already (e.g. Etayo ег al.

(1993), Houmeau & Roux (1991) and Sérusiaux (1993). Large areas are still very

insufficiently studied lichenologically. The aim of our meeting was to investigate the

area of Ste-Engráce. As this was an exploratory meeting it was decided to visit a wide

range of habitats rather than to investigate a few intensively.

The area of Ste-Engráce is famous for several impressive gorges. During

one day, collections were made in one of the most important places, gorges de

Kakouétta. Near the entrance of this gorge, we found a rich vegetation of Buxus

sempervirens with foliicolous lichens such as Byssoloma subdiscordans, Fellhanera

bouteillei, Porina hoehneliana, P. oxneri and Strigula smaragdula; on trunks we found

а.о. Celothelium buxi, Porina heterospora and P. rosei and on twigs Bacidia

laurocerasi. Trunks of Acer campestris yielded Lauderlindsaya acroglypta. Nearly

2 km in from the entrance of the gorge we collected Arthopyrenia carneobrunneola

from Corylus. Lichen growth on exposed rocks was scarce and dominated by

Lepraria spp. Another site of great lichenological importance, which we visited for

one day, is gorges d'Ehujarré. The E and W facing slopes were covered with Buxus

sempervirens-wood, mixed with Corylus, Fagus, Fraxinus and deciduous Quercus.

LICHENS FROM THE WESTERN PYRENEES 265

Here we recorded the same foliicolous lichen species as from gorge de Kakouétta.

Additional foliicolous records are Bacidina vasakii, Fellhanera nigra and Porina

leptosperma. The epiphytic macrolichen flora was luxuriant. We recorded Lobaria

amplissima, L. pulmonaria and L. scrobiculata, several Leptogium species and Sticia

species. Noteworthy crustose lichen species encountered include Arthonia didyma,

Arthopyrenia punctiformis, Bacidina phacodes, Catinaria atropurpurea, Dimerella

pineti, Eopyrenula avellanae, Lauderlindsaya acroglypta, Thelopsis rubella and in

abundance Porina rosei. Steep calcareous rock faces supported Catillaria minuta,

Clauzadea immersa, C. monticola, Collema auriforme (also growing epiphytic),

Lecania cuprea, Protoblastenia calva var. sanguinea, and P. rupestris.

The third and most eastern gorge we visited was Arpidéko Ibarra, where we

investigated only the area near the entrance. Here we found mature Fagus trees with

Acer campestris and Crataegus. Well-lit calcareous sandstone outcrops had a rather

rich covering of lichens, including Catillaria lenticularis, Сойета auriforme and

Lecania sylvestris. Overhangs and very shaded crevices yielded Lepraria lesdainii and

Leproplaca chrysodeta. On a trunk of a young Acer, Anisomeridium nyssaegenum,

Gyalideopsis anastomosans, Pachyphiale carneola and Strangospora delitescens were

found. Dimerella pineti, Gyalecta truncigena, Lecidea ocelliformis, Ramonia chryso-

phaea and Thelopsis rubella were recorded on Crataegus and Bacidia assulata,

Cetrelia olivetorum (fertile), Phyllopsora rosei and Rinodina efflorescens were

collected from Fagus.

Some old woodlands are important ecosystems in this part of the Pyrenees.

One of the most interesting woodlands visited by us was forêt d'Issaux, near col de

Labays. About ten years ago one of the members of the group had found Usnea

longissima here, but we could not refind it during the field meeting. However some

hundred meters from this locality, at the way to pic Soulaing we found Usnea

longissima with a length up to 1.20 m, growing on Abies and Fagus. The western part

of forêt d'Issaux holds a great diversity of species, but the biomass of both macro-

and crustose lichens is not exceptionally high. Species encountered include Abscondi-

tella lignicola, Arthonia leucopellaea, Micarea cinerea, M. peliocarpa, Schismatomma

pericleum and Trapeliopsis pseudogranulosa. Records from Abies are а.о. Alectoria

sarmentosa, Bryoria bicolor, Lecidea roseotincta, Lopadium disciforme, Thelopsis

rubella, Trapelia corticola and Xylographa vitiligo, Recently there is some decline of

the lichen vegetation, caused by human influence.

Pic ФАпав (2044 m) is the highest site we visited during our excursions. On

SW exposed steep, slightly calcareous schist and sandstone outcrops, between 1950

and 2000 m, rich lichen communities are developed. Amongst Acarospora impressula,

Aspicilia candida, A. cernohorskyana, Cephalophysis leucospila, Lecanora intricata,

Rimularia insularis (on Lecanora rupicola), Polysporina ferruginea and Sporastatia

testudinea we found extensive patches of Protoparmelia cupreobadia.

The second highest mountain top we visited is pic d'Orhy (2017 m) from

which many records are mentioned by Vivant (1988). This mountain top was not

Particularly rich in lichens. But we made a long walk over the mountain ridge, so this

area provided a good variety of species. On a bird perching place we encountered an

extensive colony of Candelariella aurella, Physcia caesia and Xanthoria elegans

together with Lecanora agardhiana. Terricolous records are Biatora tetramera,

Catapyrenium cinereum, C. lachneum, C. pilosellum, C. squamulosum, Leptogium

intermedium, Megaspora verrucosa, Mycobilimbia fissuriseda, M. hypnorum, M.

lobulata and Toninia rosulata. Most of the rock in this area supports a calcifuge flora

with Acarospora badioatra, Rhizocarpon atroflavescens, Thelidium decipiens, T.

papulare and Verrucaria tristis. But here we also found siliceous rocks with а.о.

Caloplaca arenaria, Lecanora gangaleoides, Polysporina simplex.

Trees and old walls in the village of Ste-Engrâce were also examined. An

unexpected lichen record in Ste-Engrâce was Rinodina flavosoralifera on Salix along

a stream. It was found growing together with Halecania viridescens, Lecanora

strobilina, Pertusaria coccodes and Punctelia subrudecta. The north wall of the church

(twelfth century) with calcareous and non calcareous stonework supported a rich

lichen flora; 30 taxa were discovered, including Catillaria lenticularis, Collema

fuscovirens, C. polycarpon, Diploschistes gypsaceus, Diplotomma epipolium, Lecania

turicensis, Lecidella stigmatea, Leptogium schraderi, Psora lurida, Toninia aromatica

and Toninia tumidula.

The scarce lichen survey in this part of the Pyrenees means that many

species are still unrecorded. This survey confirms the lichenological importance of the

study area. The western Pyrenees contain some of the richest areas for lichens in

France and Spain. From the 101 lichens and allied fungi, recorded below, 22 are new

for the lichen flora of France, 6 are new to Spain and most of them are first recorded

here from the Pyrenees.

During the excursions we have visited с. 35 localities, of which 5 main sites

are given in fig. 1. Material of all taxa mentioned below, is deposited in the private

herbaria of the authors. Species marked with * are new to France and with ° new to

Spain. Nomenclature mostly follows Purvis et al. (1992).

and 10-15 x 5-6 mm. Another species occuring in France, Cryptodiscus pallidus, is

somewhat similar in habitus, but is not lichenized. A. lignicola was previously known

only from the Czech Republic (Vézda & Pisút 1984) and Austria (Túrk & Poelt

1993). New to France.

RESUMEN — De las especies briofíticas presentes en más de tres ciudades españolas del total

de catorce estudiadas, se recopilan e interpretan los datos sobre todos aquellos rasgos genéticos,

fisiológicos, estructurales y ecológicos que se considera influyen en la consecución de un briófito

«tipo urbano », el cual se llega а identificar en doce especies «urbanicolas »: Tortula muralis

Hedw., Bryum bicolor Dicks., Funaria hygrometrica Hedw., Bryum capillare Hedw., Bryum

argenteum. Hedw., Barbula unguiculata Hedw., Grimmia pulvinata (Hedw.) Sm., Didymodon

fallax (Hedw.) Zander, Didymodon vinealis (Brid.) Zander, Lunularia cruciata (L.) Lindb.,

Orthotrichum diaphanum Brid. y Pseudocrossidium hornschuchianum (K.F.Schultz) Zander. El

perfil biológico de éstas queda definido por doce características que parecen ser las responsables

de la adaptación de los briófitos al medio urbano: alta capacidad de propagación, posiblemente

dotadas de flavonoides protectores, preferentemente dioicas, biotipo cespitoso humilde,

pulviniforme o alfombrado, saxicasmófitas o terrícolas, basófilas, nitrófilas y con alta tolerancia

a las sales, fotófilas, tolerantes al pisoteo, con mayor vigor y desarrollo bajo un aporte continuo

de nutrientes, con numerosas adaptaciones a la xerofilia, con estrategia colonizadora,

toxitolerantes о medianamente toxitolerantes al SO,, soportando por lo menos 50-60 ng/m?.

ABSTRACT — We have studied all the bryophyte species that live in more than three out of

fourteen Spanish cities. Here we present data on the genetic, physiological, structural and

ecological characteristics that are thought to be relevant in defining «urban » bryophytes. These

characteristics were present in 12 « urbanicolous species »: Tortula muralis Hedw., Bryum bicolor

Dicks., Funaria hygrometrica Hedw., Bryum capillare Hedw., Bryum argenteum Hedw., Barbula

unguiculata Hedw., Grimmia pulvinata (Hedw.) Sm., Didymodon fallax (Hedw.) Zander,

Didymodon vinealis (Brid.) Zander, Lunularia cruciata (L.) Lindb., Orthotrichum diaphanum

Brid. y Pseudocrossidium hornschuchianum (K.F.Schultz) Zander. The features which seem

responsibles for the adaptation of the bryophytes to the urban environment are: high capacity

for vegetative propagation, the presence of protective flavonoids, dioecia and growth forms with

short turfs, cushions or mats. Regarding the habitats and their ecological conditions, they are

saxichasmophytes or terricolous, basophilous, nitrophilous, photophilous and trampling-

resisting. They show enhanced survival and luxuriance under a regime of nutrient flushing, many

xerophytic adaptations, with a colonist life strategy and finally, they are toxitolerant ог

moderately toxitolerant to the SO, surviving in pollution levels of over 50-60 g/m”.

INTRODUCCION

Los briófitos tienen una presencia mucho más relevante en las ciudades que

en otros ecosistemas, ya que aquí ocupan microambientes casi exclusivos: existen

multitud de microhábitats que por su tamaño o por el tipo de sustrato, únicamente

pueden colonizarse por estas pequeñas criptógamas.

Como todos los organismos presentes en las ciudades, los briófitos se han

visto afectados en mayor o menor medida por los efectos de la urbanización, que en

ellos inciden según Taoda (1977), por:

a. La naturaleza del sustrato.

b. El clima y la polución del aire.

c. El impacto humano.

Los sustratos que encuentran los briófitos en los medios urbanos se

resumen en tres: suelo, rocas y árboles. El suelo desnudo es muy raro en la zona

altamente urbanizada, siendo los alcorques y los pequeños jardines entre edificios los

hábitats principales que se pueden colonizar; su pH suele ser 7-8. Los sustratos

rocosos de la ciudad son las paredes de hormigón, de ladrillo y de los edificios, Y

finalmente, la corteza de los árboles, más soleada, polvorienta y acidificada, es el

tercer sustrato sobre el que pueden desarrollarse los musgos y las hepáticas.

En cuanto al clima y la polución del aire, no hay duda de que la gran sequía

de las ciudades juega un papel en la desaparición de briófitos de las urbes, pero la

conclusión general es que la contaminación es la principal causa de este hecho,

En relación con los impactos humanos, la urbanización ha eliminado la

mayoría de los habitáculos donde se podían desarrollar los briófitos, y los lugares

adecuados que quedan, se encuentran sometidos a una presión antropógena muy

elevada por el pisoteo continuo, el vandalismo, las labores de clareo, limpieza,

fertilización, etc...

Los briófitos urbanos han sido especialmente estudiados en Japón, pero es

difícil comparar sus resultados con los de las ciudades europeas, dada la enorme

diferencia florística entre sus comunidades briofíticas. En España son catorce

ciudades las estudiadas en este sentido del total de 50 capitales de provincia:

Granada (Esteve & al. 1977), Catedral de Sevilla (Casas & Sáiz-Jiménez 1982), Palma

de Mallorca (Fiol 1983), Toledo (Ballesteros & Ron 1985), Badajoz (Viera & Ron

1986), Avila (Vicente & al. 1986), Madrid (Mazimpaka & al. 1988), el estudio

comparativo de estas cuatro últimas (Ron & al. 1987), Guadalajara (Ayala 1987),

Segovia (Lara & Mazimpaka 1990 y Lara & al. 1991), Logroño (Soria & Ron 1990),

Vitoria (Soria & al. 1992 y Heras & Soria 1990) y Cuenca (Mazimpaka & al. 1993),

Burgos y Huesca (Soria 1993).

En este trabajo se han intentado analizar las características de los briófitos

que parecen encontrarse bien adaptados a las ciudades españolas, reuniendo y

examinando todos aquellos rasgos genéticos, fisiológicos, estructurales y ecológicos

que se considera pueden influir en la consecución de un «tipo urbano ».

METODOLOGIA

Se han seleccionado 83 táxones que son los que estaban presentes en más

de tres ciudades españolas, del total de 14 estudiadas. De estas especies se han

recopilado los datos bibliográficos sobre corología, ecología, germinación, anatomía,

estomas, flavonoides, número cromosomático, multiplicación vegetativa, sexualidad,

biotipo, querencia, posesión de caracteres xeromórficos, estrategia y respuesta al

SO».

RESULTADOS Y DISCUSION

Flora briológica

En el análisis de la flora, se puede decir que las familias dominantes en las

ciudades españolas son: Pottiaceae, Brachytheciaceae, Bryaceae y Amblystegiaceae.

En cuanto a las especies, se han considerado las más frecuentes en los

medios urbanos las que están en más de ocho ciudades, enumeradas según orden

decreciente de aparición en las ciudades. Son las siguientes:

Tortula muralis Hedw., Funaria hygrometrica Hedw., Bryum argenteum Hedw.,

Grimmia pulvinata (Hedw.) Sm., Didymodon vinealis (Brid.) Zander, Orthotrichum

diaphanum Brid., Pseudocrossidium hornschuchianum (K.F.Schultz) Zander, Bryum

bicolor Dicks., Bryum capillare Hedw., Barbula unguiculata Hedw., Didymodon fallax

(Hedw.) Zander, Lunularia cruciata (L.) Lindb.

Entre las que colonizan las paredes de hormigón, ladrillo o muros de piedra

en la ciudad, se encuentran fundamentalmente Didymodon vinealis, Bryum capillare

y Tortula muralis que comparten los siguientes rasgos:

— a pesar de tener un amplio espectro de reacciones, se comportan en el

medio urbano como estrictamente calcicolas amortiguando mås eficazmente el efecto

del SO».

— presentan un biotipo cespitoso humilde que les permite protegerse mejor de

cualquier acción mecánica tan habitual en la ciudad, refugiarse en pequeños nichos

calcáreos y presentar una minima exposición al SO».

— se observan en ellas un gran número de adaptaciones a la xerofilia, como

la posesión de filidios apretados o incurvados y revueltos cuando secos, de márgenes

recurvados y células papilosas en algunos casos, etc... las cuales les permiten hacer

frente a la sequía característica de la ciudad.

tienen todas ellas un carácter colonizador por su gran capacidad de

propagación, bien sea a través de la fragmentación del gametófito, bien mediante

yemas protonemáticas o rizoidales. Y sin duda, se ven beneficiadas por la falta de

competición con plantas vasculares.

— en el caso de Bryum capillare, se sabe que se desarrolla mejor con un flujo

continuo de nutrientes, lo cual es típico en la ciudad (Gilbert 1968, 1970b).

Source ММНМ, Paris

288 ALICIA SORIA y M. EUGENIA RON

— y finalmente, gracias a las características mencionadas y posiblemente a

otras inherentes a las especies, se observa en diversos estudios de contaminación que

se comportan como tolerantes o medianamente tolerantes a la polución debida al

SO, (Bento Pereira & Sergio 1983; Gilbert 1968, 1970b, 1971; Johnsen & Sochting

1976; Nehira & Une 1980; Sergio & Sim-Sim 1985; Taoda 1981).

Bryum argenteum, Bryum bicolor, Barbula unguiculata, y Funaria hygrome-

trica colonizan fundamentalmente terrenos abandonados del centro de la ciudad. Es

difícil encontrar suelos desnudos en las áreas altamente urbanizadas de las ciudades:

sólo los alcorques y superficies entre los edificios. Las características compartidas por

estos musgos son casi las mismas que las citadas para las especies de paredes, a las

que se añaden otras propias del sustrato sobre el que crecen:

— a todas estas especies, al igual que ocurría con las de paredes, se las califica

como colonizadoras, esto es, capaces de extenderse rápidamente por un territorio

desnudo, creando el primer estadío de la sucesión e incluso formando el sustrato sobre

el que se desarrollen en el futuro plantas vasculares. Esta cualidad se apoya sin duda en

su alta capacidad reproductora. Bryum argenteum, Bryum bicolor y Barbula ungui-

culata comienzan dispersándose únicamente por yemas o fragmentos en el primer año

y parte del segundo, y en los años siguientes, cuando ha descendido el nivel de nutrien-

tes y ya hay cubierta vegetal, empiezan a desarrollar esporófitos (During 1979). Es muy

probable que en el comienzo de esta rápida invasión del hábitat, estos musgos formen

yemas en el protonema que inicien el proceso de dispersión. Piensa Whitehouse (1987),

Que esta posibilidad supone una gran ventaja para los primeros colonizadores de

hábitats abiertos ya que se consigue un rápido esparcimiento. Hasta el momento, de

las especies que ahora se están considerando, sólo se ha estudiado la presencia de

yemas protonemáticas en Barbula unguiculata, pero es posible que se formen en todas

las demás. En todas ellas, la velocidad de crecimiento es también muy rápida: las

esporas germinan en muy poco tiempo y originan un protonema de vida muy corta

que enseguida desarrolla los caulidios foliosos (Gilbert 1970b, 1971; Moyle Studlar

& al. 1984). La falta de competición les permite extenderse rápidamente.

— al igual que ocurría con Bryum capillare, algunas de estas especies como

Bryum argenteum y Funaria hygrometrica parecen tener mayor vigor y desarrollo

bajo un aporte continuo de nutrientes; el flujo de polvo eutrófico de la ciudad cumple

este papel, convirtiendolas en componentes importantes de las comunidades

briofiticas urbanas.

— se observa en estas especies una particular tolerancia al pisoteo. No sólo

el biotipo y la gran capacidad de multiplicación vegetativa contribuyen a ésto, sino

que como afirma Bates (1935), la característica de filidios cortos, cóncavos y

resistentes, que poseen, también condiciona en gran medida la resistencia.

— es de destacar que todas las especies que se «stán considerando son

fotéfilas, soportan altas intensidades de luz, lo que las hace idóneas para vivir en

enclaves expuestos como son los suelos desnudos de las ciudades.

— se sabe que Bryum argenteum y Funaria hygrometrica son curihalinas, y es

posible que también lo sean las restantes, ya que el medio urbano es especialmente

rico en sales solubles debido a la gran cantidad de polvo, hollín y depósitos de arena;

incluso la lluvia está enriquecida en sales por la polución.

BRIOFLORA URBANA ESPANOLA 289

— y como última característica, condicionada en parte por todas las

anteriores, se observa en estas especies una gran tolerancia a la contaminación

industrial o urbana.

Grimmia pulvinata y Orthotrichum diaphanum son especies que muestran un

comportamiento similar: según Gilbert (1970b), el factor que les permite mayor

adaptación al medio urbano es el aumento de desarrollo y supervivencia bajo un

régimen de flujo de nutrientes continuo como el de la ciudad; presentan también un

elevado número de adaptaciones al ambiente xérico característico de ella y,

finalmente, se las puede considerar entre medianamente toxitolerantes y relativa-

mente sensibles, soportando en general hasta 50-60 pg/m? de SO,.

Otra especie importante en las ciudades españolas es Lunularia cruciata la

cual, según Gilbert (1970b, 1971) y Taoda (1977), parece beneficiarse de la falta de

competición y del flujo de polvo eutrófico de las ciudades, Y sobre todo, opinan que

su éxito urbano radica en su gran capacidad reproductiva: sus esporas y yemas

germinan con gran rapidez, el protonema pasa rápidamente a un gametófito que

tiene un crecimiento posterior muy acelerado. Todo ello hace que sea una hepática

resistente a la acción del SO).

Del comportamiento urbano de las dos especies que quedan: Pseudocrossi-

dium hornschuchianum y Didymodon fallax no se conoce mucho. Ambas parecen

encontrarse en descampados, zonas de demolición de edificios o destrucción de

terraplenes. Sus características les permiten la colonización de estos ambientes:

pueden formar yemas en el protonema, resisten altas intensidades de luz, son

fundamentalmente terrícolas y basófilas, con lo que pueden desarrollarse bien en

estos medios con bastantes residuos orgánicos y con restos de materiales de

construcción, los cuales, en su mayoria, son de naturaleza básica. También presentan

adaptaciones a la xerofilia que sin duda les ayudan a soportar la pérdida de agua en

estos enclaves tan expuestos.

Germinación y anatomía

Es muy bajo el número de datos que existe sobre estos aspectos para poder

extrapolar algún tipo de conclusión en relación con posibles adaptaciones a este

biotopo particular. Los principales estudios sobre germinación se han centrado en los

patrones de desarrollo del protonema de diversas especies (Nehira 1983, 1988;

Nishida 1978), mientras que los de anatomía han profundizado fundamentalmente

en el estudio de los tejidos conductores, dada la gran importancia que supone el

conocimiento de su estructura y composición desde el punto de vista filogenético

(Hébant 1977; Kawai 1976; Schreirer 1980).

Estomas

Con los estomas ocurre lo contrario: sólo hay 10 táxones de los

seleccionados sin datos sobre sus estomas. La información de la que se dispone, sin

Source : MNHN, Paris

290 ALICIA SORIA y M. EUGENIA RON

embargo, es bastante pobre, ya que no existe una buena tipificación como la que hay

en las plantas vasculares.

Tras el trabajo de Paton & Pearce (1957), la posibilidad de extraer alguna

conclusión de tipo ecológico se hace muy lejana, ya que ni siquiera está claro el papel

de los estomas en los briófitos. Para estos autores, las condiciones del hábitat no

parece que influyan en la ausencia de estomas ni que ésta suponga un inconveniente

en la lucha por la existencia. Parece que en las ciudades es bastante mayor el número

de especies con pocos estomas, lo que Paton & Pearce (1957), consideran como

posible adaptación a ambientes secos. No obstante, no hay que ser muy estrictos con

este tipo de afirmaciones y hay que tener en cuenta la complejidad del proceso

adaptativo de los briófitos y las posibles convergencias, ya que por ejemplo, en el

grupo de «número bajo de estomas» de estos autores se encuentra Eucladium

verticillatum, especie considerada higrófita, con 6 estomas. Asímismo, en el grupo

con más de 50 estomas, en teoría propio de ambientes húmedos, se encuentran

Bryum bicolor, Bryum argenteum, Bryum radiculosum, Funaria hygrometrica, etc...,

que están consideradas como xerófitas o xero-mesófitas.

Flavonoides

Se ha tenido en cuenta la presencia o ausencia de flavonoides en esta

recopilación, por el posible significado adaptativo que puede tener la posesión de

flavonoides como protección frente a depredadores (Kawasaki & Ohta 1976;

Asakawa & al. 1980; Liao 1993), radiaciones, enfermedades (Banerjee & Sen 1979;

Castaldo-Cobianchi & al. 1988; Huneck 1983; Spjut & al. 1986, 1992), etc...Sin

embargo, se vuelve a tener el problema de la escasez de datos: sólo hay datos de un

10 % de los briófitos conocidos y además, la metodología utilizada no siempre ha

sido la correcta, conduciendo a resultados erróneos. Sólo 15 del total de especies

consideradas en este trabajo, tienen datos sobre la presencia de flavonoides.

Cualquier conclusión es muy arriesgada con tal escasez de información; simplemente

se puede destacar la presencia de flavonoides en especies tan «urbanas » como

Bryum argenteum, Bryum caespiticium, Funaria hygrometrica y Lunularia cruciata

(Markham & Given 1988; Markham & Porter 1974; McClure & Miller 1967; Weitz

& Ikan 1977).

Número cromosomatico

A pesar de lo que la poliploidia pueda suponer de mecanismo adaptativo

ligado a la estrategia vital se aprecia en estas especies urbanas una cierta tendencia

a la diploidia, aunque algunas de las especies tipicamente colonizadoras de las

ciudades como: Tortula muralis, Funaria hygrometrica, Bryum bicolor, Bryum

capillare, Grimmia pulvinata, etc..., si sean poliploides о diploides-poliploides (Fritsch

1982; Smith 1978). Con estos datos no puede extraerse ninguna conclusión clara que

relacione el número cromosomático con la adaptación al medio urbano.

BRIOFLORA URBANA ESPANOLA 291

Multiplicación vegetativa

Según Longton y Schuster (1983), el tipo monoico es superior al dioico en

la reproducción. En los medios urbanos, los briófitos dioicos parecen ser más

abundantes que los monoicos, con lo que han de desarrollar muchos propágulos para

extenderse por el medio. En este estudio de la brioflora urbana española, el número

de táxones con y sin multiplicación vegetativa es casi el mismo. Sin embargo, en este

último grupo están incluidos los pleurocárpicos, quienes, según Nehira & Nakagoshi

(1990), en las ciudades presentan como patrón dispersivo, la regeneración desde los

filidios o caulidios. Este sistema lo utiliza un gran número de briófitos, dada la

potencialidad de las células de estas plantas.

Al contrario que en la germinación de las esporas, en la fragmentación la

formación del protonema se ve frecuentemente omitida o se forma después de la

aparición del gametófito, en su base, ya que mientras existan algunas células que

proporcionen nutrientes a la planta en formación, el protonema no se hace necesario.

No hay duda de que esto puede ser una ventaja considerable para la supervivencia

de los briófitos en las ciudades, ya que así se evita la exposición del protonema, fase

muy sensible al SO, y a otros agentes contaminantes. Además de la fragmentación,

existe otro sistema de multiplicación vegetativa que pasa inadvertido en la

herborización y posterior identificación; es el de la formación de yemas protonemá-

ticas, cuya existencia detectó Whitehouse (1987) en numerosas especies y puede que

también estén presentes en el grupo que se ha denominado «Sin multiplicación

vegetativa ». Whitehouse opina que es probable que para los primeros colonizadores

de hábitats abiertos (muchos ambientes urbanos), la formación de yemas protone-

máticas antes de la aparición de los gametófitos, suponga una importante ventaja al

favorecer un rápido esparcimiento.

Resumiendo, sí parece importante la multiplicación vegetativa en los

briófitos de estas catorce ciudades españolas, ya que en casi todas las especies

seleccionadas se han detectado, bien propágulos y yemas claramente observables,

bien sistemas más enmascarados como la fragmentación o formación de yemas

protonemáticas, que les ofrecen la posibilidad de dispersarse vegetativamente de una

manera eficaz en estos medios urbanos.

Y finalmente, en relación con el tema, se observa que existe una correlación

entre multiplicación vegetativa y sexualidad. De las especies seleccionadas, un 82%

de las que presentaban mecanismos de propagación vegetativa, son dioicas, mientras

que son monoicas un 18%.

Biotipo

En relación con los biotipos de las especies urbanas se ha observado, de

mayor a menor proporción, la siguiente progresión:

Cespitoso humilde > Alfombrado > Pulviniforme > Anual >

Entramado > Cespitoso alto» Juláceo — Flabeliforme.

Source - MNHN, Paris

292 ALICIA SORIA y M. EUGENIA RON

Este es exactamente el mismo gradiente de disminución de la resistencia a

la polución que muestra Gilbert (1970b). Los biotipos « Cespitoso humilde» y

« Pulviniforme » exponen menos superficie a los posibles agentes contaminantes.

En la ciudad existen muchos enclaves abiertos y expuestos a la insolación

que son colonizados por briófitos con biotipo cespitoso humilde, anual y pulvini-

forme fundamentalmente. Esto no hay duda que está conectado con el hecho de que

la luz inhibe el alargamiento de los ejes y conduce a estas formas de crecimiento. Con

estos biotipos son frecuentes los musgos con puntas piliferas en los filidios, carácter

relacionado con altas intensidades de luz, puesto que parece que se produce una

reflexión de la radiación con la consecuente reducción de la pérdida de agua (Proctor

1979).

También los biotipos predominantes, cespitoso humilde, alfombrado y

pulviniforme, presentan una mayor capacidad de retención de agua.

El biotipo alfombrado, el segundo en importancia en estas ciudades, ofrece

posibilidades de cruzar pequeñas distancias a otros lugares más adecuados y

generalmente aumenta la habilidad competitiva de las plantas, tan importante en un

medio inhóspito como el de la ciudad (Warming 1884).

En el medio urbano, la tolerancia al pisoteo es un factor que permite una

considerable ventaja adaptativa. Según Moyle Studlar £ al. (1984), los céspedes

humildes tienen una gran resistencia al pisoteo ya que presentan un crecimiento lento

con las puntas de los caulidios protegidas por el resto de las plantas formadoras del

césped y por ser empujados hacia dentro en el aplastamiento. En el biotipo

alfombrado también los ápices de crecimiento se encuentran bastante protegidos.

Querencia

Sobre la querencia de estas especies urbanas hay que decir, en relación con

el factor agua, que los xerófitos (46 %) son los predominantes en todas estas

ciudades, lo cual era de esperar dado el carácter marcadamente mediterráneo de casi

todas ellas, a lo que se puede sumar la condición xérica inherente a cualquier medio

urbano.

Respecto al factor luz, la tendencia lumínica de los briófitos urbanos es la

fotofilia (40%). Lo que se viene diciendo del medio urbano en general, es que existe

una reducción de la luz del 15-20% en comparación con el medio rural (Landsberg

1962, 1970). En estas catorce ciudades es posible que ni haya niveles demasiado

eleyados de polución ni la aglomeración de edificios sea tan grande como para

provocar tal reducción de la luz que sólo permita la existencia de briófitos esciófilos.

Por otra parte, hay que tener en cuenta las excepcionales características de

luminosidad de las ciudades españolas en comparación con el resto de las europeas

y americanas, que es donde se han hecho la mayoría de los estudios de este tipo.

Además, en general, en las urbes españolas estudiadas los parques no son tan densos

como los europeos, eliminando muchos habitáculos sombreados donde se pueden

desarrollar briófitos esciófilos. En estos catorce medios urbanos, los ambientes que

con más frecuencia se ofrecen a los musgos y hepáticas son los jardines más o menos

expuestos, muros de construcción, descampados, medianas entre carreteras, caminos

en parques, etc..., todos ellos sometidos a altas intensidades de radiación lumínica,

por lo cual es lógico pensar que los fotófilos tengan más facilidades para invadir el

medio.

En relación con las propiedades químicas del sustrato, los porcentajes más

altos son los de los calcifilos (36%), indiferentes (30%) y basófilos (19%), dentro de

los cuales se encuentran los nitrófilos. También en este caso las proporciones son las

esperadas, dada la naturaleza básica de los suelos sobre los que se asientan la

mayoría de las ciudades estudiadas. A esto se suma el hecho de que el suelo del

medio urbano es en muchos casos el resultado de la acumulación de materiales de

construcción (casi siempre de carácter básico) y de deyecciones y residuos ricos en

nitrógeno, con lo que, aunque el sustrato original fuera ácido, casi todos los

microhábitats de la ciudad tendrían características básicas. Por otra parte, son los

basófilos en general los que pueden sobrevivir mejor en zonas contaminadas por

SO», ya que tienen la posibilidad de refugiarse en enclaves fuertemente calcáreos

donde no se encuentra el ión HSO, que es el componente más tóxico en este tipo

de polución (Goossens 1976; Hoffman 1971).

En cuanto a los hábitats, el que presentaba mayor número de especies era

el suelo húmedo y sombreado, que sin duda es el medio idóneo para el crecimiento

de los briófitos y que en las ciudades se encuentra localizado en los parques y en

jardines muy protegidos. En este hábitat se han encontrado tanto briófitos xerófitos

como higroesciófilos. No obstante, le sigue muy de cerca el ambiente formado por

los suelos secos y expuestos: alcorques, descampados, caminos, jardines abandona-

dos, etc... Las proporciones de terrícolas y saxicasmófitos son prácticamente las

mismas. Esto puede significar que los briófitos no se han distribuido principalmente

en los hábitats presionadas por la influencia de la contaminación, sino por la

disponibilidad de habitáculos adecuados para su desarrollo, ya que según exponen

Leblanc & Rao (1975), el gradiente ascendente en cuanto a sensibilidad al SO, es:

Terrícolas — Saxicolas > Epifitos

Caracteres xeromérficos

Lo que se puede extraer de los resultados en estas catorce ciudades, es que

la inmensa mayoría de las especies que viven en ellas, concretamente un 92,7%, están

dotadas, bien por la influencia del ambiente, bien por convergencia evolutiva, de una

serie de estructuras xeromórficas que les ayudan a sobrevivir en el medio xérico

urbano.

Estrategia vital

Siguiendo el criterio y terminología de During (1979) en relación con la

estrategia vital de las especies urbanas, se ha resumido la proporción de cada grupo

en el siguiente gráfico:

Source : MNHN. Paris

294 ALICIA SORIA y M. EUGENIA RON

Itinerante anual 5%

Itiner. vida larga 4%

Fugitivas 1%

itiner.vida corta 2%

Perennes 29%

El primer aspecto digno de reseñar es el predominio de las especies de vida

corta (colonizadoras, itinerantes anuales, itinerantes de vida corta y fugitivas). Esto

concuerda perfectamente con el papel de los briófitos en el medio urbano: pioneros

en las fases iniciales de la sucesión o en ambientes hostiles y sometidos a frecuentes

perturbaciones, que son imposibles de colonizar por plantas vasculares. Se trata de

musgos de pequeño tamaño que rápidamente ponen en marcha sus mecanismos

reproductivos.

El porcentaje de especies perennes que se aprecia, representa aquellos

briófitos instalados en los microhábitats más protegidos y más perdurables que se

pueden encontrar en determinadas zonas de algunos parques de estas ciudades. Son

musgos de mayor tamaño, con mayor capacidad de crecimiento y que no presentan

mecanismos precoces de reproducción.

Respuesta al SO,

Se dispone de datos bibliográficos en este sentido de 47 táxones (Barkman

1969; Bento-Pereira & Sergio 1983; Daly 1970; De Sloover & Leblanc 1970; Düll

1974; Gilbert 1968, 1970a, 1970b, 1971; Goossens 1976, 1979, 1980; Hoffman 1974;

1978b, 1983; Winner е! al.1988), aunque algunos de ellos son contradictorios. Es de

destacar que las especies con un carácter más tolerante se encuentran en un gran

número de ciudades, con lo que parece desprenderse la idea de que estas especies

toxitolerantes lo son por poseer una serie de características que les permiten, tanto

soportar la acción del SO, o de otros contaminantes, como sobrellevar las otras

condiciones de vida que les impone el medio urbano.

CONCLUSIONES

Tras este análisis global de la brioflora de las ciudades españolas que se

encuentran estudiadas, se puede concluir que las 12 especies tipicamente « urbani-

colas » en ellas son: Tortula muralis, Bryum bicolor, Funaria hygrometrica, Bryum

capillare, Bryum argenteum, Pseudocrossidium hornschuchianum, Grimmia pulvinata,

Barbula unguiculata, Didymodon vinealis, Didymodon fallax, Orthotrichum diaphanum

y Lunularia cruciata.

El perfil biológico de estas especies es el siguiente:

— Con alta capacidad de propagación.

— Posiblemente dotadas de flavonoides protectores.

— Preferentemente dioicas.

— Con biotipo cespitoso humilde, pulviniforme o alfombrado.

— Saxicasmófitas o terrícolas.

— Basofilas, nitrófilas y con una alta tolerancia a las sales.

— Fotéfilas.

— Tolerantes al pisoteo.

— Con mayor vigor y desarrollo bajo un aporte continuo de nutrientes.

— Con numerosas adaptaciones a la xerofilia.

— Con estrategia colonizadora.

— Toxitolerante o medianamente toxitolerante al SO,, soportando por lo menos

50-60 ug/m?.

Todas estas cualidades pueden ser las responsables de la adaptación de los

briófitos al medio urbano, si bien algunas deben de jugar un papel mucho más

importante que otras en este proceso. Todo estudio sobre cada una de estas

características contribuirá a ampliar el conocimiento sobre el papel ecológico de los

briófitos en los medios urbanos y sobre su valor como bioindicadores del grado de

urbanización, de calidad de biotopos y de contaminación de las ciudades para

conseguir ciudades más limpias y más integradas en el medio natural.

RESUME — Lecanora rubicunda Bagl. lichen épiphyte, jusqu'ici connu seulement en Ligurie,

Sardaigne, Catalogne et aux Canaries, est mentionné pour la première fois en Afrique

continentale, dans deux localités du nord du Maroc. Nous donnons une description complète de

ce taxon basée sur nos spécimens,

INTRODUCCION

Dentro de la con la linea de investigación sobre « Flora y vegetación

liquénica del Norte de Africa », se han recolectado diferentes ejemplares de Lecanora

rubicunda Bagl., un liquen conocido previamente de Italia (Nimis 1993), litoral de

Cataluña (Boqueras & Gómez Bolea 1986, Giralt 1991 y Boqueras 1993) y Canarias

PLAGIOCHILA BRITANNICA PATON (HEPATICAE)

W TO SWITZERLAND AND CONTINENTAL EUROPE

N.G. HODGETTS

Joint Nature Conservation Committee, Monkstone House, Peterborough, PE] 1JY, UK.

ABSTRACT. — Plagiochila britannica, a plant hitherto known only from the British Isles, is

recorded from the Swiss Alps.

On a visit to the Klausenpass in Uri Canton, Switzerland, during a

symposium on endangered bryophytes in Europe held at Zúrich in September 1994,

T collected several Plagiochila specimens from high altitude limestone outcrops in

alpine grassland. Most of these proved to be P. porelloides (Torrey ex Nees) Lindenb.

but one was determined as P. britannica Paton. This determination was subsequently

verified by D.G. Long and J.A. Paton. P. britannica was growing among limestone

rocks beside a stream on a north-facing slope, along with typical alpine calcicoles and

more widespread species, including Barbilophozia lycopodioides, Blepharostoma

trichophyllum, Cephalozia bicuspidata, Conocephalum conicum, Jungermannia зрр.,

Lophozia badensis, L. bantriensis, Scapania aequiloba, Ctenidium molluscum, Dicho-

dontium pellucidum and Pseudoleskea incurvata (nomenclature following Grolle 1983

for hepatics and Corley ef al. 1981 with amendments by Corley & Crundwell 1991

for mosses).

The details are as follows :

Switzerland, Uri Canton : Chrüchen, Klausenpass, 46°52’ N 8°54’ E, с. 2000m alt.,

among limestone rocks beside stream on north-facing slope in alpine grassland, 7

Sept. 1994, N.G. Hodgetts 3019 (Z).

P. britannica tends to be intermediate in size between P. porelloides and P.

aspleniodes (L.) Dum. The Swiss specimen, which is not fertile, resembles typical P.

britannica collected in the UK in most respects. A shoot and some leaves are

illustrated in fig 1. Although most of the leaves are considerably less toothed than

shown in the illustration in the original description (Paton 1979), the drawings of P.

britannica in Smith (1992) show leaves with few teeth, so the dentition of the leaf

margin is clearly a variable character in this species. In general the marginal teeth of

P. britannica tend to be fewer in number but slightly larger than those of P.

porelloides. The leaf apex of P. britannica is frequently emarginate. The cells of the

leaf and the stem cortex are significantly wider than those of P. porelloides, and the

trigones tend to be less prominent. The cell size differences are the most reliable

distinguishing characters. Indeed, in the small amount of Swiss material examined,

the differences in cell size between the two species seem to be even more pronounced

than in British material. These differences (using Swiss material of both species) are

summarised in table 1 and illustrated in fig. 1. As mentioned by Paton (1979), leaf

cell size is a variable character in this group of species, but the large cells of P.

britannica can always be detected on examination of the cells in several leaves from

different shoots. Indeed, once one is familiar with the species, it is often possible to

detect the large pellucid cells of P. britannica in the field. Refer to Paton (1979) for

a detailed description of Р. britannica and a discussion of the differences between P.

britannica and the North American P. arctica Bryhn & Kaal. and its varieties.

Table 1. Differences in cell size between P. britannica and P. porelloides.

This is the first time P. britannica has been found outside Britain and

Ireland and the first record from such a high altitude, although this is easily

accounted for by the climate difference between Britain and Switzerland. In view of

the large amount of apparently suitable habitat in the Alps and elsewhere in

continental Europe, it is likely that the species will be found in other localities.

Herbarium specimens of P. porelloides from limestone regions in continental Europe

should also be checked.

ACKNOWLEDGEMENTS. — My thanks to E. Urmi and his colleagues at the Institut far

Systematische Botanische at the University of Zürich for organising the field trip during the

symposium on endangered bryophytes, and to D.G. Long and J.A. Paton for confirming the

identity of the specimen and commenting on the draft of this note.

Les espèces du genre foliacé Xanthoparmelia (Ascomycotina : Parmeliaceae) sont parmi

les lichens les plus abondants sur les rochers ou le sol des régions arides ou semi-arides

d'Amérique du Sud. Ils occupent des habitats très variés jusqu'à 4000m d'altitude. Leur couleur

typiquement vert brillant ou vert jaune, due à la présence d'acide usnique dans le cortex

supérieur, et leur surface inférieure avec des rhizines rendent le genre facilement reconnaissable.

Mais pour mieux caractériser un spécimen, il faut considérer aussi les polysaccharides de la paroi

cellulaire, et si possible, les caractères de l'apothécie. Sur la base de la richesse en espèce, le genre

Xanthoparmelia est considéré comme un genre de lHémisphére Sud. Cependant la prépondérance

de specimens avec des propagules asexuées et la rareté de la reproduction sexuée indiquent que les

Xanthoparmelia pourraient étre originaire d'un autre continent, comme le Gondwanaland.

Après avoir donné l'historique, les caractères morphologiques, anatomiques, chimiques

du genre, les auteurs décrivent 77 espèces де Xanthoparmelia présentes en Amérique du Sud en

détermination plus rapide des espèces de ce genre. La classification du genre Grimmia est

généralement basée sur le sporophyte; malheureusement celui-ci est souvent absent, aussi

Greven base sa clé sur les caractères du gamétophyte (trois groupes selon des critères tirés de

la feuille)

Après avoir évoqué le port, l'habitat, la couleur, le mucron foliaire, la forme de la

feuille, la nervure, Paréolation, la reproduction, la capsule, l'auteur discute deux groupes

taxonomiques complexes (le groupe du Grimmia alpestris, et le groupe du Grimmia trichophylla),

montrant ainsi un grand degré de variation de certaines espèces et la difficulté de les délimiter.

А partir des données de 13 pays européens, Greven établit la liste des espèces de Grimmia (14)

à inscrire sur la liste rouge des espèces menacées.

Le corps du volume est constitué par le traitement spécifique. Pour chaque espèce, sont

donnés les principaux synonymes, la description accompagnée d'une illustration [détail (figure

dans le texte — on pourra regretter à ce sujet le parti pris de ne pas mettre d'échelle), port (photo

en couleur)], l'écologie, la distribution, la discussion portant sur des points taxonomiques et/ou

morphologiques, les spécimens examinés. Pour compléter utilement l'ouvrage : un index des

taxons (рр.145-149), une bibliographie (pp. 150-154) dont la présentation laisse à désirer (lignes

non justifiées, citations non uniformisées [comme pour les espéces]), et deux appendices [liste et

distribution mondiale de Grimmia Hedw. (pp. 155-158) et liste des personnes (avec leurs dates)

citées dans le texte (pp. 1598-160)]

L'aire étudiée correspond à l'Afr3 de l'Index Muscorum, ie. de Madagascar au Sud

jusqu'aux Seychelles, région de l'Océan Indien comprenant de nombreuses petites iles, visitées

dés 1804 par J.B.G.M. Bory de Saint-Vincent. Le catalogue est avant tout un registre des

données publiées sur les hépatiques récoltées dans cette région. Toutefois l'auteur a vu bon de

nombre de spécimens types et critiques, lui permettant d'en faire une évaluation, d'établir leur

synonymie et leur distribution (en prenant souvent l'avis de ses collègues). Aussi, de nombreux

noms d'espèces ont pu être clarifiés comme syn. nov. et des déterminations ont pu être corrigées.

6 genres, qui ont été signalés dans les Iles d'Afrique de l'Est, sont ainsi rejetés de l'aire étudiée

Alobiella (Spruce) Schiffn., Hygrolembidium Schust, Jubula Dumort., Lembidium Mitt.,

Megaceros D. Campb. et Spruceanthus Verd.

Le corps de l'ouvrage est constitué de : Arrangement taxonomique des genres avec des

commentaires sur certains genres (Lophocolea/Chiloscyphus, Plagiochila, Lejeunea| Rectolejeunea,

Metalejeunea, Microlejeunea, Archi-Lejeunea| Archilejeunea) (pp. 21-23) ; liste alphabétique des

espèces avec synonymie, dsitribution dans l'aire étudiée (et renvois bibliographiques), références

aux illustrations (les synonymes sont catalogués dans le même ordre alphabétique avec renvoi

au nom accepté) (pp. 21-139); espèces douteuses et exclues (pp. 140-158). Complètent ce

catalogue : une bibliographie rigoureuse et très bien présentée (pp. 160-176), les liste des

nouveaux noms, des nouveaux synonymes, des nouvelles typifications (p. 177-178). Nouveaux

noms proposés : Cheilojeunea compressa (Herz.) comb. nov. (= Strepsilejeunea), C. autoica

(Steph.) comb. nov. (= Physocolea), Lejeunea brittoniae (A. Evans) comb. nov. (= Rectolejeu-

nea), Metalejeunea gen. nov. (type : Jungermannia cucullata Reinw. et al.), M. cucullata (Reinw.

et al.) comb. nov. (= Jungermannia), Riccardia nudiflora (Steph.) (= Aneura), К. ramosissima

(Steph.) comb. nov. (= Aneura).

L'ensemble de cet ouvrage est bien présenté ; il est toutefois dommage que ce genre de

catalogue ne soit pas traité comme un dictionnaire avec des hauts de page significatifs. Il n'en

demeure pas moins que ce travail sera un outil indispensable aux floristes travaillant sur cette

région et les régions adjacentes.

hors-texte (aut. : Wihlelmstrasse 48, D-35418 Buseck ; éd. : Gebr. Borntraeger Verl.,

Johannesstr. 3A, D-70176 Stuttgart, ISBN 3-443-64162-8, prix : DM 80.00).

Dans les provinces de Misiones et Corrientes (Argentine NE), 12 associations épiphytes

et 3 associations épixyles (8 associations épiphytes et 1 association ‘sur troncs en décomposition

dans les forêts pluvieuses de la prov. de Misiones, et 5 épiphytes et 2 sur troncs en décomposition

dans les forêts semi-toujours vertes de la prov. de Corrientes) ont été reconnues. L'écologie, la

structure, la composition floristique, les aspects phytogéographiques des associations sont

donnés avec leur synsystématique. Toutes ces communautés sont nouvelles pour la science.

Dans les chapitres d'introduction l'aire étudiée est décrite (relief, climat, végétation),

l'importance des épiphytes dans les forêts tropicales et la terminologie employée et l'histoire de

la sociologie des épiphytes sont commentées. Dans les relevés phytosociologiques, 59 plantes

vasculaires, 80 mousses, 62 hépatiques et 51 lichens ont été déterminés ; la majeure partie des

espèces ont une distribution néotropicale, mais parmi les cryptogames il faut noter de

nombreuses espèces à distribution pantropicale ou avec une disjonction afro-américaine. 14

espèces de mousses et 5 hépatiques sont nouvelles pour l'Argentine : Chonecolea acutiloba,

Frullania ericoides, Metzgeria psilocraspeda, M. convoluta, Plagiochila raddiana, Calyptothecium

duplicatum, Cyclodictyon varians, Erpodium biseriatum, Erythrodontium longisetum, Fissidens

prionodes, Leucomium strumosum, Macromitrium nematosum, Neckeropsis pabstiana, Orthosti-

chopsis tenuis, Pinnatella minuta, Porotrichum expansum, Prionodon densus, Syrrhopodon

parasiticus var. parasiticus, Tortula pagorum.

La végétation épiphyte est différente d'une province à l'autre, principalement à cause

du gradient de précipitation qui diminue d'est en ouest. L'écologie des epiphytes, notamment

dans les zones tropicales, complète ce travail.
