Figure 321. Polyporus frondosus. One-fifth natural size. 



Polyporus leucomclas. Fr. 



Leucomeias is from two Greek words, leucos, white, and melas, black. 

 The pileus is two to four inches broad, fleshy, somewhat fragile, irregularly 

 shaped, silky, sooty-black ; flesh soft, reddish when broken. 



The pores are rather large, unequal, ashy or whitish, becoming black when 

 drying. 



The stem is one to three inches long, stout, unequal, somewhat tomentose, 

 sooty-black, becoming black internally. The pileus and stem become black in 

 places. 



The spores are cylindric-fusoid, pale-brown, 10-12x4-5^. 



They are usually found in pine woods. The caps are often deformed and 

 are easily broken. The pores resemble those of a Boletus. The plant is quite 

 widely distributed. The one in Figure 322 was found in Massachusetts by Mrs. 

 Blackford, and I photographed it after it was partially dry. It is probably the 

 same as P. griseus, P.
