138 POI.YPOREI. 



This is one of the most common dry Polypora fungi growing in the 

 Valley. There is barel}- a half-decayed stump that does not have a 

 beautiful rosette growing. It does not seem to be very particular for a 

 host, for it grows on any kind of wood. 



P. pergamenus. 



Pileus, coriaceous, thin, effuso-reflexed, villous, zoned, 

 cinereous-white, with colored zone. 



Pores, unequal, torn, violaceous, then pallid. 

 Almost as common as the versicolor and has the same habit. 



P. cinnabarina. vSchw. Cinnabar Polyporus. 



Pileus, dry, more or less spongy, flesh light or yellowish 



red, fibrous on top of pileus. 



Pores, carmine, small, round, entire. 



This species is easily identified by its beautiful carmine red color, of 

 both pileus and pores. 



Common on decayed cherry logs. 



P. hirsutus. Fr. 



Pileus, corky, coriaceous, convex plane, hairy, with rigid 

 bristles, zoned or rather sulcate with concentric ridges, of one 

 color, which is white. 



Pores, round, obtuse, white or grayish, then brown. 



Common on different kinds of decayed wood. 



P. cupulseformis. B. & C. 



Pileus, cup-shaped, resupinate, attached to its host with a 

 thin pellicle. 



Pores, small, brown, shallow. 



Common on decayed chestnut branches. This is a peculiar species 

 inasmuch as it looks like a Peziza. When I first found it, I took it for a 

 dry Peziza, but could not detect any ascospores, so I was at a loss until 

 Prof. C. H. Peck helped me out of the dilemma.
