STEREUM Pers. 

 arepeoQ, solid, hard. 



Stereum is distinguished by the smooth, plane, fruiting- 

 surface and the velvet)- or hairy upper surface of the cap. 



In some species the plants have a well-defined central stem, 

 in others the side of the cap is attached to the substratum, 

 while in still others the cap lies upon its back (resupinate). 



Stereum complicatum Fr. (complicated). 



Mansfield, July (364). 

 Stereum fasciatum Schw. (bundled).

 Stereum gausapatum Fr. (gausapa, a shaggy woolen 

 cloth).

 Stereum sericeum Schw. (silky). 



Bolton, Hanmer; Mansfield, Aug. (365). 



CORTICIUM Fr. 



Cortex, bark or rind. 



These plants are always resupinate, the caps lying upon 

 their backs, closely attached to the surface of the bark of logs. 

 The edges are frequently free and curl outward. The fruit- 

 ing-surface is perfectly smooth and often polished. When 

 dry, the fruiting-surface is often cracked, clue to the contrac- 

 tion of the mycelial tissue of the cap. The genus, in many 

 ways, resembles Stereum. but the latter genus is often shelv- 

 ing, the surface of the cap velvety, and the fruiting-surface 

 uncracked when dry. 



Corticium incarnatum (Pers.) Fr. (flesh-colored). 



Goshen, Underwood. 

 Corticium salicinum Fr. (pertaining to the willow). 



Goshen, Underwood ; New Haven, Clinton. 

 Corticium vagum B. & C. (uncertain) var. Solani.
