MUSHROOMS, EDIBLE AND OTHERWISE 



surface a pale cream-color and minutely mealy, pores not decurrent but ending 

 with the beginning of the stem. 



The stem is uniformly attached to the concave margin of the cap; attenuated 

 downward ; whitish below, but near the cap it changes to the same tint. The 

 peculiar manner of attachment of the stem will serve to identify the species, 

 which I have found several times near Chillicothe. The specimen in the illustra- 

 tion was found on the State farm, and photographed by Dr. Kellerman. 



Polyporus. Fr. 



Polyporus is from two Greek words meaning many and pores. Tn this genus 

 the stratum of the pores is not easily separated from the cap. Most of the 

 species under this genus are tough and corky. Many grow on decayed wood, a 

 few on the ground, but even these are inclined to be tough. Very few of those 

 growing on wood have a central stem and many have apparently no stem at all. 



Figure 319. Polyporus picipes. Two-thirds natural size. Note the black stem, which gives name to the species. 



Polyporus picipes. Fr. 

 The Black-Footed Polyporus. 



Picipes is from pix, pitch or black, and pes, foot. 



The pileus is fleshy, rigid, coriaceous, tough, even, smooth, depressed either 

 behind or in the center ; livid with a chestnut-colored disk. 



The pores are decurrent, rounded, small, tender, white, finally reddish-gray.
