Hebeloma socialis n. sp. 
Pileus fleshy but thin, convex, becoming plane or nearly so, 
glabrous, slightly viscid when moist, dingy yellowish white, flesh 
concolorous, taste nauseous; lamellae thin, close, slightly rounded 
behind, adnexed, at first whitish, then yellowish, finally brownish 
ferruginous; stem short, fibrous, floccose fibrillose, hollow with a 
small cavity, white; spores brownish ferruginous, elliptic, .00025- 
.0008 of an inch long, .00016-.0002 broad. ; 
Pileus 8-15 lines broad; stem 12-18 lines long, 1.5-3 lines thick. 
Closely gregarious or subcespitose. Among short grass in pas- 
tures and golf ground. Menands. October. Distinguished from 
our other white or whitish species by its peculiar habitat and 
mode of growth and by its small spores. 
Hypomyces boletinus n. sp. 
Perithecia minute, conic or subglobose, closely nestling in a 
pallid or whitish subiculum, pale red or orange; asci slender, 
linear, .004-.005 of an inch long, scarcely .0003 broad; spores sub- 
fusiform, continuous, acuminate or apiculate at one end, .0008-.001 
of an inch Jong, .00025 broad. 
Qn some unrecognized decaying boletus, associated with 
Sepedonium chrysospermum. It differs from H. 
polyporinus, to which it is most closely related, in its 
more highly colored perithecia and longer spores, and from 
H. boleticola in the color of the subiculum. 
Hydnum balsameum n. sp. 
Resupinate with a very thin whitish or pallid subiculum ; aculei 
mere conic brown points closely scattered but not crowded, giving 
to the surface a brown color. 
Decorticated wood of balsam fir. North Elba. September. It 
sometimes grows on the bark also. 
Hydnum macrescens Banker in lit. 
Resupinate, effused, the thin subiculum less than 1 mm thick, 
ochraceous, subfarinaceous, specially in the thinner portions and 
on the woody substratum, rimose, the margin indeterminate; 
mycelium white, arachnoid, spreading in places beyond the subic-
