39. Polyporus fissus Berk. Lond. Jour. Bot. 6 : 318. 1847. 



This plant has been generally known to American mycol- 

 ogists as P. picipes Fr. It is very common from September 

 until December on dead deciduous wood, especially hickory 

 and elm. It is easily recognized by the reddish brown, leath- 

 ery, pileus, which is depressed or infundibulifonii, and by the 

 stipe, which is black at the base. The pileus sometimes 

 reaches a width of 20 cm. or more, and the stipe is eccentric 

 or lateral.

 species found in the late fall around sttmips of deciduous 

 trees, especially of the ash. It is normally stipitate and 

 alutaceous in color, but specimens in the writer's collection
