Membranaceous, very thin, inseparable from the matrix, 

 broadly effused, margin fibrillose, whitish. 



Hymenium continuous, even, dingy-sulphur or ochraceous, 

 pulverulent, becoming brownish. Spores ochraceous, ellipsoid, 

 with a minute apiculus at the base, 11 to 12 x 6 to 7 /*. 



On bark of Prunus, Riverside. October, 1903. Harper. 

 Coniophora suffocata (Pk.) Massee. 



Effused, indeterminate; subiculum whitish or pale-tawny, 

 composed of intricate webby filaments. 



Hymenium tawny-brown, of a smooth waxy appearance when 

 moist, dusted with the spores and more or less rimose when dry, 

 revealing the paler subiculum through the chinks. 



Spores elliptical, colored, 10 x 7.5 p. 



On charred sticks in pine woods. Millers, Indiana. Novem-

HYPOCHNUS. 



Resupinate, floccose, collapsing or mold-like; basidia four- 

 spored on long lax hyphae, with two to four (rarely six) sterig-

Hypochnus spongiosus Schw. 



Soft, becoming hard, umber-purple, hymenium powdery, 

 branched. The apices of the branches that proceed from the 

 hymenium are pilose. 



On dead sticks in damp places. Millers. Harper. Professor 

 Burt, to whom specimens were sent for identification, says that it 

 is probably the above species, but that he has not seen the original 

 Schweinitzian specimen.
