lateral confluence; resupinate portions about 2 cm. in diam- 
eter present in one collection. 
On rotting frondose wood and logs in dense forests, caus- 
ing a pocketed rot. Cuba and Porto Rico. February and 
March. Frequent. 
H. cubensis is related to H. reflexa in structure, but its fruc- 
tifications are smaller and thinner than those of the latter, 
and are nearly always umbonate-sessile or dimidiate—only 
very rarely reflexed—and do not become glabrous and dark- 
colored, with resemblance to H. rubiginosa. Such ample col- 
lections of H. cubensis have been made that it seems as though 
this species should have been described heretofore, but I have 
failed to find anything in earlier work to which these speci- 
mens may be referred.
