11. M. cubensis Burt, n. sp. 
Type: in N. Y. Bot. Gard. Herb.

Fig. 9 ing ochraceous buff to fawn-color, the minute 
M. cubensis. folds about 4 to a mm., sinuous, branching, 
B pl % 7% forming shallow, sinuous pores and then grow- 
ing out somewhat into granular or irpiciform 
projections; in structure 300-400 y thick, with the hyphae 
longitudinally and densely arranged, thick-walled, hyaline, not 
шеги Фед, not nodose-septate, 44-5 шіп diameter; no cystidia; 
spores hyaline, even, allantoid, 3X4 и, strongly curved. 
Fructifications 14-4 ст. in diameter, sometimes laterally 
confluent, with the reflexed margin 1-4 mm. broad. 
On bark of dead wood of a frondose species in low, dense, 
virgin forest. Cuba. March. 
This species is related to M. tremellosus and M. ambiguus, 
from both of which it is distinct by the absence of a gelati- 
nous layer, and from the former, furthermore, by its thin, 
pliant fructification and minute folds and pores and from the 
latter by minute folds and pores, very small, allantoid spores, 
and coarse hyphae.
