soft. Greyish red, brownish red, or tawny brown. 4-6 
inches broad. 
Flesh—W hite or yellowish; reddish beneath the skin.

Habitat—W oods, swamps. 
POLY PORACEZE 
The fungi with pores permanently united to the surrounding 
tissue and to each other form a large and important group, the 
Polyporacee. With but few exceptions they are leathery, corky, 
membranous, or woody. 
Nearly six hundred species have been reported from America.
