LENZITES. 305 



broad, forked and anastomosing, straight, dingy white; 

 spores elliptical, smooth, 4 x 2 //,. 



Lenzites betulina, Fries, Epicr., p. 405 ; Cke., Hdbk., p. 

 360; Cke., niustr., pi. 1145A. 



On trunks and stumps, especially birch, 



Gills at first thickish, somewhat porous, dingy, then 

 thinner and with the margin acute. 



Dimidiate, sessile, corky-coriaceous, firm and rigid, flat- 

 tened, tomentose, usually indistinctly zoned, the true zones 

 sometimes darker, 1-2 in. broad, becoming pale, greyish- 

 white ; flesh floccose, white ; gills radiating from the base, 

 straight, simple or branched, often anastomosing, about 3 

 lines broad, dingy white, margin acute. (Fries.) 



Lenzites flaccida. Fr. (figs. 8, 9, p. 301.) 



Pileus 1-2| in. long, 1-1^ in. broad, more or less flabelli- 

 form, horizontal, narrowed behind to the point of attach- 

 ment, coriaceous, flesh about 1 line thick, flaccid, unequal, 

 strigose, zoned, tinged grey or brown, then pale, margin 

 same colour; gills broad, crowded, straight, unequally 

 branched, white then pallid ; spores elliptical, smooth, 

 7 x 5/t. 



Lenzites flaccida, Fries, Epicr., p. 406 ; Cke., Hdbk., p. 360 ; 

 Cke., Illustr., pi. 1145 B (the gills too narrow). 



On trunks and stumps of beech, &c. 



Differs from L. betulina in the coriaceous thin pileus, 

 scarcely 1 line thick, easily bent, strigosely hairy, at first 

 whitish then sordid, zones similar in colour ; gills thick, 

 firm, straight, very broad, simple, or branched, with shorter 

 ones, intermixed, at first shining white then pallid. I have 

 never seen the gills anastomosing in this species, but con- 

 stantly obfurcate, i.e., forked towards the base. (Fries.) 



Lenzites saepiaria. Fr. 



Pileus 1-4 in. long, 1-1^ in. broad, horizontal, hard, zoned, 

 strigose or tomentose, wrinkled, bay or sometimes umber, 

 flesh thick, brown, margin yellowish ; gills thick, branched 

 and anastomosing, yellowish; spores subglobose, smooth, 

 5 X 4 /*.
