Genus Lenzites 



PolypOrUS CircinatUS (SEE PLATE FACING PAGE 118) 



Polyporus circinatus quite often has one cap within 

 another. The caps are thick, round, without zones, velvety, and 

 of a rusty-yellow colour. The lower surfaces of the caps, with 

 the stems are woody and corky, but the upper surfaces of the 

 caps are soft and woolly. The stem is swollen and covered 

 with yellow wool. The pores are decurrent, minute, and un- 

 broken, and of a dusky grey colour. This is a handsome species, 

 especially remarkable for its double cap. The stem is an inch 

 long and almost equally thick. The cap is three to four inches 

 wide, and the flesh is uniform in colour.

 bearing trees. Trametes cinnabarina is bright red, and common 

 on birch and cherry. Trametes suaveolens is white, and grows

 firm, and without zones, 

 woolly and pale; the mar- 

 gin of uniform colour; the 

 lamellae radial, somewhat
