216 FUNGUS-FLORA. 



ing, clay-colour, zoned with raised lines ; pores minute, an- 

 gular, white. 



Pohiiwrm (Inoderinci) Wijnnei, B. & Br., Ann. Nat. Hist., 

 n. 807 ; Berk., Outh, p. 270. 



Running over twigs, grass, &c. 



Thin, incrusting various substances, with the margin more 

 or less broadly reliected, tan-coloured, sericeous, and marked 

 with raised lines ; pores -r,^ in. across, angular, white, acquir- 

 ing a slight tint like that of the pileus in drying. This 

 species has somewhat the habit of P. amoiyhus, but is not of 

 so fleshy a texture. Specimens have been submitted to Fries, 

 who says that he is unacquainted with the species, and I 

 have therefore no hesitation in proposing it as new. (B. & Br.) 



FOMES. Fries. 



Pileus hard and woody from the first, texture consisting 

 of interwoven hyphae, covered with a hard, rigid, crustaceous 

 cuticle, zoneless, but often concentrically sulcate ; perennial, 

 formius: successive strata, but the latest formed stratum alone 

 living. 



Fomcs, Fries, Nov. Symb., p. 31 ; Cooke, Praec, p. 117. 



Polyjjorus, most authors. 



Stem central, lateral, dimidiate, or sometimes entirely 

 rcsupinate. The present genus includes those species 

 included in Folyporus as understood in the old sense, cha- 

 racterised by a hard, woody,, often concentrically sulcate 

 pileus, and by the stratose tubes, resulting from the peren- 

 nial nature of the species.
