FOMES. 223 



On wood. Pileus 1-2 in. broad. In the original descrip- 

 tion it is queried as to whether the pores and margin are 

 always naked. 



Pomes vegetus. Fr. 



Pileus horizontal, 8-12 in. broad, flattened, glabrous, 

 opaque, brown, concentrically sulcate, annual zone broad, 

 flesh floccose, loose, very thin, coloured; cuticle of the 

 second year thick, separable ; tubes umber, stratose, seceding, 

 each yearly stratum separated from the preceding by a 

 floccose layer ; mouths of the tubes minute, roundish, white 

 at first. 



Polyporus vegetus, Fries, Epicr., p. 464 ; Cooke, Hdbk., p. 274. 



On trunks of lime, elm, &c. Amongst the largest of 

 species, often reaching a foot across during the first season. 

 Allied to Fames applanatus, from which it is distinguished by 

 the very thin flesh, and the distinctly stratose tubes, eacii 

 annual formation being separated from the preceding by a 

 floccose layer. Plane below, at first white, margin very 

 smooth, shining, sterile, narrow. 



Fomes fulvus. Fr. 



Exceedingly hard, convex above and below, attached by a 

 broad base, hence triangular in section ; pUeus even (not 

 concentrically zoned), at first villous, fulvous then greyish, 

 flesh subferruginous ; pores short, about ^ in. rounded, 

 minute, cinnamon, at first with a greyish-yellow bloom.

 p. 205. 



On decaying trunks, especially poplar. Pores not distinctly 

 stratose. 



Fomes annosus. Fr, 



Very irregular in form, often horizontal and imbricated ; 

 pileus convex, becoming plane, tuberculoso-zoned, coarsely 

 radiately rugulose, during the first year brown, silky, margin 

 whitish, second season covered with a glabrous blackish- 

 brown rigid cinist ; flesh rather thick, whitish ; pores at first 

 pure white, about i in. deep, medium size ; spores colourless, 

 elliptic-oblong, 6 x 4 |«,.
