Stereum rameale Schw. 



Specimens collected at River Forest by Harper and Moffatt 

 were named by Prof. Burt as above. Fries, Elench. p. 178, says 

 that he has seen the original specimen of Schweinitz, and is unable 

 to distinguish it from Stereum hirsutum (Willd.) Fr. 



Stereum ochraceo-flavum Schw. 



Coriaceous-membranaceous, thin. Pileus effused-reflexed, 

 strigose-hirsute, white or pale yellow. 



Hymenium even, glabrous, bright-ochraceous becoming pale. 



On the underside of small fallen branches. Frequent. 

 Stereum purpureum Huss. 



Soft-coriaceous. Pileus effused-reflexed, subimbricate, zonate, 

 villous-tomentose, pallid or whitish. 



Hymenium naked, even, glabrous, purplish. 



On Prunus rirginiana, Millers, Ind. The upper surface of the 

 young pileus is pallid, but with age becomes purplish-black, and 

 rarely rugose with a white border. Hy menial surface purple or 

 lilac, often with a white margin. The plants by confluence 

 sometime? encircle small branches. 



Stereum fasciatum Schw. 



Coriaceous; pilei caespitose, plane, grayish-ciereous, villous, 

 with brown shining zones, the base narrowed and substipitate. 



Hymenium even, glabrous, pallid brick-color; spores globose, 

 5 to 6 or 5 x 6 /A. 



On fallen trunks and branches. Common. Surface of the 

 pileus banded witji bright zones of various colors, like that of 

 Polystictus versicolor. Hymenium sometimes lilac-tinted. 



Stereum rufum Fr. 



Rufous, becoming fuscous, coriaceo-cartilaginous, erumpent, 

 tuberculiform then somewhat round, marginate, smooth beneath. 



Hymenium gray-pruinose, at length bullate-tubercular. 



On dead pine, Millers. Xot rare. Harper. 

 Stereum striatmn Fr. 



Coriaceous; pileus effused-reflexed, undulate, rugose-striate, 

 subtomentose, fuscous-ferruginous, paler and filamentous within. 



Hymenium ashy-white, smooth when in full vigor; spores 

 subglobose, 5 to 6 /A. 



Thin, wholly adnate or 'attached by a narrow base, and 

 flabelliform, with intermediate stages. 



Xear Chicago. Harper.
