Type: in Kew Herb. and Curtis Herb., and of Thelephora 
setosa in Brit. Mus. Herb. 
Fructifieations broadly reflexed and with a narrow, resu- 
pinate base, or dimidiate, sessile, imbricated, laterally con- 
fluent, very thin, drying pliable, with upper surface rough 
with coarse, strigose, matted 
«злу nn very shallowly concen- 
----- trieally sulcate; hymenium gran- 
E S> ES = ular, snuff-brown; in structure 
150-400 џ thick, with a narrow 
pon setigerous layer consisting of 
the hymenium, and with the 
hyphal layer composed of longi- 
tudinally arranged, colored hyphae 2 и in diameter which 
curve outward and become interwoven to form the upper sur- 
face of the pileus—no dense, dark zones present; setae scat- 
tered, 60-756 yu, tapering from the base, emerging up to 30 
н, some starting from the subhymenium but mostly from the 
hymenium; spores hyaline, even, 32 yw as seen on basidia. 
Pilei of fructifications 1-24 em. long, 1-5 cm. broad, some- 
times resupinate on areas up to 5X3 em. 
On dead frondose wood on the ground in forests. Cuba, 
Jamaica, and Venezuela. October to March. 
H. aspera may be recognized by its thin, pliant pileus, which 
is rough on the upper surface with strigose matted fibers, by 
granular hymenium which is as granular as in Thelephora 
terrestris, and by the short, brighter-colored mycelial strands 
which form the resupinate margin.
