uncommon to find several large clusters of the plant about 

 the base of a stump, especially beech. It resembles G. 

 frondosa (Dicks.) Gray, but the pileoli are fewer in number 

 and much larger. In the fresh specimens the hymenium 

 turns to black when bruised, and this characteristic will 

 identify the species. Found from July until September.

 Boletus frondosus Dicks. 



Commonly known as Polyporus frondosus (Dicks.) Fr. 

 Resembles the preceding species in form and habit but 

 easily separated. The pileoli are much narrower and more 

 numerous, and are grayish cinerous in color. The plant 

 generally attains a breadth of 20 or 30 cm. and a height of 

 20 or more cm. Found at the bases of elm and oak stumps 

 during the late fall.

 Polyporus berkeleyii Fr. 



The same as P. anax Berk. ''Nobilissimus inter-omnes 

 mihi cognitos Polyponis," to quote from Fries. A rather 

 common species found around oak or ash stumps in August 

 and September. It has globose, echinulate, spores which 

 will identify it, as no other closely related species has such. 

 Capt. Mcllvaine cites an instance of a plant of this species 

 being found near Boston several years ago, which "was 

 ftdly four feet high and from two to three feet broad. "^
