The genus Morganella Zeller, as emended by Kreisel and Dring,
consists of seven tropical Lycoperdaceae, one described by them and
six transferred from Lycoperdon and Bovista. In my opinion Ly-
coperdon albinum Cooke is certainly a Morganella, becoming the
eighth known species of the genus.
Morganella albina (Cooke) P. Ponce, comb. nov. Lycoperdon
albinum Cooke in Massee, Journ. Roy. Microsc. Soc. 1887: 723. 1887.
Zeller, Myc. 40: 648. 1948 (an emended description). L. albidum
Cooke in Lloyd, Myc. Wrt. 5: 582. 1916, sphalma.
Type. — In Cooke collection at Kew.
Type locality. — Brazil.
Habitat. — On rotted wood or on humus.
Distribution. — Brazil and Puerto Rico.
Fructifications 4-12 mm. in diameter, globose, subspherical, ses-
sile, white to yellowish, smooth; peridium furfuraceous, thin; gleba
yellowish first, then turning gray; subgleba obsolete; capillitium
none; paracapillitium hyaline, slender, flaccid; spores 2.5-4.2^ di-
ameter, asperate, clay color.
Material examined. — Slide No. 58690 in Lloyd Herbarium, pre-
pared by Lloyd from the type of Lycoperdon albinum Cooke in Kew
Herbarium; Stevenson No. 3171 from Puerto Rico (Lloyd Cat. No.
24665); Stevenson No. 5441 from Puerto Rico (Lloyd Cat. No.
51776); Stevenson No. 4265 from Puerto Rico in Pathological and
Mycological Collection in Beltsville, Maryland.
Discussion. — This species was discovered by Cooke who estab-
lished the name Lycoperdon albinum based on a collection from
Brazil found in Kew Herbarium. This name was published by
Massee (1887) in his Monograph of the Genus Lycoperdon. Lloyd
(1916) studied the type material and found it in a very poor condi-

tion. When he studied the material collected in Puerto Rico by
Stevenson he identified it correctly as Lycoperdon albinum, but he
applied the name Lycoperdon albidum, a sphalma.
Zeller (1948) corrected the error, and confirmed the Puerto Rican
material as Lycoperdon albinum Cooke and made an emended de-
scription.
In the original description of Massee and in the emended one of
Zeller the floccose hyaline threads of the gleba are considered to be
capillitium, but as application of the Cotton Blue technique produces
the reaction of paracapillitium in the concept of Kreisel (1962), it

is necessary to remove this species from Lycoperdon and place it in
Morganella.
In addition, many other characters of this species are typical
of Morganella, the size of the fructification, the reduction of the
subgleba, the size of the spores, and the lignicolous habit.
In view of these morphological and taxonomical similarities, I
propose the transfer of this species to Morganella.
