Hymenochaete cinnamomea Pers. 



Effused, irregularly confluent, appressed, cinnamon, the under 

 surface and circumference fibrillose-strigose. 



Hymenium fleshy, soft, glabrous, naked, concolorous, cracked 

 when dry. Spores elliptical with a minute basal apiculus, pale 

 cinnamon, 11 to 12 x 7 to 8 p. (Massee.) 



On a rotten log, Riverside. June. Harper. Described by 

 Persoon as a Thelephora, placed by Fries in the genus Corticium, 

 and by Massee in Coniophora. 



Hymenochaete ferruginea Bull. 



Coriaceous-rigid, thin, tough, fuscous-ferruginous; pileus 

 effused-reflexed, densely concentrically sulcate, leprous-villose, 

 becoming smooth. 



Hymenium finely velvety, setules few, acuminate-conic, 40 to 

 60 x 6 to 8 /tx. Spores ellipsoid, 6 x 3 to 4 /x. Hymenium when 

 dry ochraceous-cinnamon, inner texture the same color. 



Superficially resembling H. rubiginosa, from which it differs in 

 the larger spores and the hymenium appearing almost smooth 

 under a lens (Massee). 



Fallen logs and branches. Millers. June. 



CORTICIUM. 



Pileus resupinate or reflexed, the hymenium arising from a 

 thin layer of mycelium which is not separated from the sub- 

 stratum by a strigose or floccose layer, soft, somewhat waxy, 

 often cracking when dried. Spores sessile, not septate.
