Illustrations: Lloyd, loc. cit. 
Type: in Kew Herb. and Curtis Herb. 
Fructifications resupinate, effused, gelatinous, adnate, loosen- 
ing from the substratum about the margin in drying, pallid at 
first, now pale smoke-gray, bearing granules about 9 to the mm. ; 
in structure 500-800 v thick, composed of densely interwoven 
and crowded, suberect, gelatinous-walled, hyaline hyphae 3 wu 
in diameter; granules about 100 v. high, about 50 u in diameter 
at the base, containing an axile sheath of fine hyphae and an 
accumulation of erystalline matter; basidia longitudinally sep- 
tate, 15 x 12 w; spores hyaline, even, flattened on one side, 
6-716 x 4-5 u. 
Covers an area on bark of 5 x 4 cm., fractured on one side 
and one end. 
Under side of rotten logs. Cuba. January. 
Heterochaete gelatinosa is much thicker and more gelatinous 
than our other American species and has smaller spores than 
H. andina and H. sublivida. Its fructifications are so large 
and thick that it should attract notice of collectors but it would 
probably be classed as one of the Hydnaceae although it must 
be notably gelatinous. 
Specimens examined. 
Cuba: C. Wright, 230, type (in Curtis Herb.). 
H. microspora Burt, n. sp. 
Type: in Mo. Bot. Gard. Herb. and N. Y. Bot. Gard. Herb. 
Fructifications resupinate, effused, at first a white floccose 
mycelium which persists later as a subiculum and bears on its 
surface a thin, waxy, hymenial layer, pinkish buff in the her- 
barium, more or less cracked, and showing through the cracks 
the filaments of the subiculum; in structure 100-150 w thick,
