THE TUBE-BEARING EUNGI 



409 



somewhat reniform, zoneless, the oblique vertex in the form of an umbo ; pellicle 

 thin, separating; flesh white, very thick. 



The pores are short, round, minute, unequal, separable from the pileus when 

 fresh, but really concrete with it; white or tinged with brown, developing slowly; 

 when mature there are peculiar hair-like scales attached to the pore-surface, 

 making the plant look like a Hydnum when viewed from the side. It is found 

 wherever the birch tree grows. When young and fresh it is edible, but with a 

 strong flavor unpleasant to many. In this state the deer eat it. The specimen 

 in Figure 337 was found in Wisconsin, and photographed by Dr. Kellerman. 

 This species is the Piptoporus suberosus (L.) of Merrill. 



Polyporus cinnabarinus. Schw 

 Cinnabar Polyporus. 



Cinnabarinus like cinnabar (vermilion). The pileus is dry, more or less 

 spongy, pliant, rather thick, fibrous on top ; flesh light or yellowish-red, shelving. 



The pores are carmine, quite small, round, entire. 

 This species is quite common 

 in the woods about Chillicothe. 

 It is easily identified by the beau- 

 tiful carmine color of the pileus 

 and the pore surface, the latter 

 being a shade darker than the 

 former, as will be seen in Figure 



338 



The specimens photographed 

 were found in December. They 

 grow on dead logs and branches, 

 commonly on the oak and wild 

 cherry, sometimes on maple. It is 

 called by some authors Trametes 

 cinnabarina.

 Common Effused Polyporus. 



Vulgaris, common. Quite broadly effused, very thin, adheres closely to its 

 host; even, white, dry. Circumference soon smooth and the whole surface com- 

 posed of firm, crowded, small, round, nearly equal pores. 



Effused on dead wood, fallen branches, and frequently on moist boards.
