Species usually growing on decaying wood. Type species. — Morganella mexicana Zeller, Mycologia 40: 650. 1948. Type locality. — Mexico. Specimens: Macbride, Sonora, Guaymas (NY). The material deposited by Zeller in the Morgan Herbarium at the University of Iowa cannot be found. The material from Newfield, New Jersey, Ellis 5013 (NY), cited as paratype by Zeller, has been identified by Kreisel (1967) as Morganella velutina (Berk, ex Mass.) Kreisel and Dring. Geographic distribution. — Morganella is pantropical, with most of the species, M. fuliginea, M. velutina, M. puiggarii, and M. stercoraria, occurring in tropical America; M. velutina reaches the temperate zone in eastern North America, and M. puiggarii reaches it in South America; M. fuliginea covers a wide area in tropical America, and also occurs in West Africa; M. stercoraria occurs only Library of Congress Catalog Card Number: 73-156851 Publication 1127 27 I MAY ] 5 1972 I AY 17 1Q7? blOLOGY LIBRAE 28 FIELDIANA: BOTANY, VOLUME 34 in the West Indies; M . afra occurs in tropical Africa; M. purpurascens has a wide distribution in tropical Asia; M. samoense is known only from Samoa; M. compacta and M. subincarnata are the only two extra-tropical species — M. compacta occurring only in New Zealand and M. subincarnata in the temperate zone of North America. It appears possible to me that the Caribbean region may have been the geographical center of development of Morganella, at least of the American species, and perhaps of all of them. Morganella fuliginea and M. velutina are especially abundant in Caribbean and circumcaribbean lands. Discussion. — Morganella is easily distinguished from Lycoperdon, Calvatia, Bovista, and other members of the Lycoperdales, by its small size, habit of growing on wood, absence of capillitium, and the presence of abundant glebal membranes and paracapillitium. The peridium has two layers. The outer one is used to separate the species: it is velvety or velutinous in M. velutina and M. puiggarii; tuberculose in M . fuliginea, M. purpurascens, M. subincarnata, and M. samoense (the tubercules composed of pluricellular hyphae); granulose in M. afra; with large spines in M. compacta. The lignicolous habit is characteristic of all species of Morganella except M . stercoraria, which lives on cow dung. In the remaining Lycoper- dales, only Lycoperdon pyriforme lives on decaying wood and Lycoperdon (Bovista) acuminata in the bark of living trees; both of these species have abundant capillitium in the gleba. Although Zeller's decision to place Morganella in the Lycoper- daceae instead of the Mesophelliaceae was, according to his own statement, "for convenience" until more was known as to the mem- branes in the gleba, he was correct, not only because of the mem- branes which are also present in the gleba of Lycoperdon, Calvatia, Geastrum, and in the family Mesophelliaecae, but also because, as he later established (Zeller, 1949), the genera of the Mesophelliaceae have three layers in the exoperidium and Morganella has only two. Kreisel (1967) accepted the fact that Morganella falls within the Lycoperdaceae in spite of its lack of capillitium, and separated it from the Mesophelliaceae because of the presence of three layers of exoperidium in the latter.

Fructifications 1 cm. diameter, depressed-globose to pyriforme; mycelium white, fibrous; exoperidium fuscous above, lighter below, minutely granular; endoperidium light brown, thin, smooth to very minutely aerolate; gleba light brown, becoming greyish as the spores are shed; pseudocolumella and glebal membranes inconspicuous; subgleba light brown, chambered, the chambers some- times very small and few, or even absent; mouth irregular; paracapillitium hyaline, septate, rarely branched, encrusted, 3.5-6.5 /z diameter; spores light yellowish, globose, 3.5-4.5 n diameter, minutely asperulate, with a short pedicel. Type.—Dixon 4, Yinahin, Ashanti, Ghana. Habitat. — On decayed wood. Distribution. — Tropical Africa.

Type.— Apiai (Apiahy), leg. Puiggari, Sao Paulo, Brazil (LPS). Habitat. — Gregarious on rotting fallen trunks in forest. Distribution . — Brazil, Paraguay. Discussion. — This species' principal character is the tricho- dermal palisade of elements in chains that integrate its exoperidium. The swollen terminal cells separate it from M . fuliginea. This species has been considered as belonging in the genus Radiigera, subgenus Endoplectidium by Singer et al. (1963), but the lack of capillitium, and the exoperidium of two layers, place it in Morganella. It differs from Bovista, where Spegazzini put it, by the lack of capillitium.

Fructifications 3 cm. diameter, depressed-globose to pulvinate, usually with a marked umbo, sessile on a white cord-like mycelium; exoperidium mahogany color shading to tan below, darker when dry, persistent, densely velutinous, consisting of setose hyphae mostly 100 n long and clavate; endoperidium smooth, very thin; mouth small and torn; gleba umber, membranes not prominent, pseudocolumella small and flattened, not well marked; subgleba tan, compact; paracapillitium branched, smooth, hyaline, cyanophilus, septate, 3-4 p. diameter; spores globose, 3.5-4 ju diameter excluding ornament, spines up to 1 n long, often with flattened tips. Type.—Fendler 235 and 236, Colonia Tovar, Venezuela (K). Habitat. — On decaying wood. Distribution. — Eastern North America: Florida, North Carolina, New Jersey. South America: Venezuela, Brazil. Discussion. — This species may be separated from related species in the genus by its setose exoperidium of clavate hyphae. Material observed.— UNITED STATES.

SPECIES DUBIAE There are two species of Lycoperdon, L. brasiliense Fries and L. pisiforme Hennings, which in the opinion of several authors can be placed in Morganella. PONCE DE LEON: REVISION OF MORGANELLA 41 Lycoperdon brasiliense Fries, Syst. Myc. 3: 40, 1829. For this species we have only the description of Fries, as the type cannot be located. He said, "L. brasiliense, peridio membranaceo persistente globoso punctato- scabro, ore obtuso, floccis laxis, sporidiis fuliginosis . . . Peridio membranaceo floccido, extus tantus punctato-scabro, ut Lycogala, cui exoleto simile est . . . Ad truncos Brasiliae. Beyrich!" The type was collected by Beyrich in Brazil, but his specimens have not been found in any of the herbaria to which he sent his collections. Lycoperdon pisiforme Hennings, Bot. Jahrb. 23: 556. 1897. Bring (1964) and Kreisel (1967) have suggested that this species might be placed in Morganella, mostly because of its small size, its habit of growing from a subiculum on dead wood, and its hyaline capillitium. However, the spores from the type of this species in the Lloyd collection have a different episporium, which is thicker than that of Morganella, and its sculptures are not spines or warts, but elongated ridges as in the spores of Lycogalopsis. Because of the characteristics observed in the episporium, the shining peridium, and the extensive white shining subiculum men- tioned in the description, it is assumed that this species may belong in the genus Lycogalopsis Fischer. SPECIES EXCLUSA Restudy of the type of Lycoperdon albidum Cooke (Morganella albida P. Ponce) and comparison with the type of Lycogalopsis solmsii Fischer shows these two to be identical in their clamp con- nections, in the disposition of the basidia in groups, the short sterigmata of the spores, and the constitution of the peridia. It is necessary, therefore, to place the first two names in synonomy under Lycogalopsis solmsii Fischer, as indicated by Dennis (1953) and as suggested by Bring in a personal letter to me in April, 1970.
