132 POLYPOREI. 



P. Schweinit^ii. Fr. 



Pileus, thick, spongy, then corky, strigoso-tomentose, 



rough, bright brown. 



Pores, large, variable, and torn, sulphur greenish. 



Stem, thick, very short or obsolete, ferruginous. 



Very scarce in the Valley. Only met with it in one locality and that 

 was in the Minesite mixed woods of pine and chestnut. 



Section 2. Pleuropus. Stem lateral. 



P. picipes. Fr. 



Pileus, fleshy, rigid, coriaceous, even, smooth, depressed 

 behind. 



Pores, decurrent, rounded, small, tender, white, at length 

 reddish-gray. 



Stem, excentric and lateral, equal, firm, at first velvety, 

 then pitch black below. 



Common on old stumps throughout the Valley. Has a liking for 

 willow stumps. 



P. lucidus. Fr. Shining Polyporus. 



Pileus, corky or woody, flabelliform, sulcate, rugose, 

 yellow, then reddish chestnut, varnished and shining as well 

 as the lateral, equal stem. 



Pores, long, minute, white, then cinnamon. 



Stem, reddish, varnished, sometimes sessile. 



Pileus two to six inches broad. 



Common on oak stumps. There are many different forms, varying so 

 much so as to disguise the natural type. The pileus may be stipitate, it 

 may be sessile, or assume some other fantastic form. The most won- 

 derful specimen that I ever saw was found in Schuylkill County, by 

 a Mr. Horn, of Bethlehem, Pa., who may still be in possession of it. 

 There were at least fifteen fully developed pilei on different branches, 

 with odd forms. Some mimicked a profile of a man's face ; some were 

 in the form of a boot ; while others were elongated in the form of fingers.
