ent it appears distinct from tlie latter by its adnate, very 

 thin fructification and short-celled, hyaline hyphae of irregu- 

 lar form and mode of branching. 



Specimens examined: 

 New Hampshire: Madison, W. G. Farlow, 15, type; Cho- 



corua, W. G. Farlow, 16.

Type : in Farlow Herb, and in Burt Herb. 

 Fructification effused, soft, felty-membranaceous, tomen- 

 tose, light mineral-gray, the margin thinning out and inde- 

 terminate; in structure 400/x thick, with hy- 

 phae hyaline, 4/* in diameter, thick-walled, no- 

 Q Q dose-septate, densely interwoven for 100/a next 



the substratum and then suberect and ascend-

This species is marked by its color, two-layered fructifica- 

 tion, thick-walled and hyaline hyphae, and spores hardly 

 more than rough-walled. H. cinerascens occurs on wood, 

 is drab-gray, and has very thin-walled and delicate, loosely 

 arranged hyphae 2-3/". in diameter, and smaller spores than 

 H. epigaeus. H. clialyheus, as received from Bresadola, is 

 pale at the surface only and has colored hyphae constituting 

 the greater jDart of the fructification.
