These plants have a more or less fleshy texture when 

 young, becoming harder with age. The genus is distin- 

 guished from Fomcs by its lack of stratose layers of tubes 

 within the cap. The pileus is not zoned, and it has a thicker 

 flesh than the species of Polystictus. 



The members of this genus are numerous, and are varied 

 in their habit of growth. In some species the stem is central, 

 but more often it is attached at one side of the cap (lateral), 

 and sometimes it is wanting, the plants becoming sessile. 



The species are commonly found growing on wood, in 

 nearly all sections of the state, and are decidedly varied in 

 their individual colors, shapes, and general habits of growth. 

 P. bctulina is so abundant upon grey birch trees that it is fa- 

 miliar to the most inexperienced collector.
