Hebeloma socialis n. sp. 



Pileus fleshy but thin, convex, becoming phane 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, flocoose fibrillose, hollow with a 

 small cavity, white; spores brownish ferruginous, elliptic, .00025- 

 .0003 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, .00'l-.()05 of an inch long, scarcely .0003 broad; spores sub- 

 fusiform, continuous, acuminate or apiculate at one end, .0008-.001 

 of an inch long, .00025 broad. 



On some unrecognized decaying boletus, associated with 

 Sepedonium chrysospermum. It differs from H . 

 p o 1 y p o r*i n u s , to which it is most closely related, in its 

 more highly colored perithecia and longer spores, and from 

 H . b 1 e t i e o 1 a in the color of the subiculum. 



Hydnum balsameum n. sp. 



Resupinfite 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 wood}' substratum, rimose, the margin indeterminate;
