LENTINUS. 311 



quite entire, crowded ; but the substance is much firmer, as 

 in Lcntinns. (Fries.) 



In some respects very similar to P. ringens, but dififers 

 in the distinctly mealy pileus, and the smooth, not striate 

 margin. Pileus h in. or a little more. (Cooke.) 



Very remarkable. Analogous with Pamis ringens, but most 

 nearly allied to P. stypticua. Pileus resupinate, coriaceous, 

 orbicular, saucer-shaped, sessile, adnate and attached by the 

 vertex, margin free and involute, h in. or a little more across, 

 scurfy-downy and pallid externally. From the observations 

 of Lindblad the pileus is viscid at first. Gills meeting at a 

 central point, crowded, quite entire, dry, dark ochraceous. 

 (Fries.) 



Panus Stevensonii. B. & Br. 



Pileus spathulate, olive-yellow, stem dilated above, convex, 

 golden, slightly hispid ; gills narrow, entire ; flesh greenish- 

 yellow. 



Panus Stevensonii, Berk k Broome, Ann. Xat. Hist., 

 no. 1796 ; Cke., Hdbk., p. 359. 



On oak. 



I have not seen a specimen of the above, consequently 

 cannot add to the scanty diagnosis. The species is pre- 

 sumably small in size. 



LEXTINUS. Fries, (fig. 6, p. 301.) 



Pileus coriaceous, tough, hard and dry when old, not soon 

 decaying, always more or less irregular; gills becoming dry, 

 tough, simple, unequal, thin, margin acute, toothed or 

 irregular, more or less decurrent ; stem when present, hard 

 and firm, central, excentric, or lateral ; spores white, 

 smooth. 



Lentinus, Fries, Epicr., p. 45 ; Cke., Hdbk., p. 354. 



Allied to Panus in the dry, coriaceous nature of the pileus 

 and gills, but distinguished by the toothed or serrate margin 

 of the gills. 



All the species grow on wood.
