"Pileus thin, convex, more or less umbilicate, densely cespitose,
1-2.5 cm. broad; surface glabrous, white, subfuscous at the center,
margin striate-sulcate, depressed, often elevated with age: lamellae
adnate-decurrent, distant, broad, white: spores ellipsoid, smooth,
hyaline, 5 X 3 y: stipe slender, glabrous, white, pellucid hollow,
dilated at the apex, strigose at the base, 2.5-3 cm. long.
"Type locality: Cuba.
"Habitat: On decayed logs in woods.
"Distribution: Cuba, Porto Rico, and Jamaica; also in Paraguay."
Observations. I have studied Earle's specimens, as previously
stated (p. 409), and have found the microscopic characters to be the
same as those for M. hondurensis, except that the spores are a little
larger and the pleurocystidia more abundant. Since my concept
has been based on the material at the New York Botanical Garden,
Murrill's synonymy and description are given above. I have not
seen fresh specimens and have not had an opportunity to study the
type of M. euspeirea or the types of the species Murrill placed in
synonymy with it. For a comparison with M. hondurensis see page
409.
