CLASSIFICATION 211 



C. — Resupinati 



* Cap flesliy, miiform in texture. 



P. porrigens. — Entirely white. Cap thin, tough, sessile, at first 

 resupinate, then more or less turned over, expanded from the base 

 and becoming ear-shaped, fan-shaped, or almost circular, smooth, 

 base more or less downy, 2-3 in. long, il in. broad ; gihs radiating, 

 very narrow, rather crowded. 



Resembling P. petaloides in habit, but differing in colour, and in 

 the absence of a narrowed, stem-like base. 



On old pine trunks, etc. Usually imbricated. 



P. septicus. — Cap downy, resupinate, at first closely pressed to the 

 wood on which it grows, with a minute, downy stem, 1-2 lines 

 long, which soon disappears, leaving the cap reflexed, and apparently 

 sessile, shining white, up to | in. across ; gills radiating from the 

 point of attachment of the stem, rather distant and broad, white. 



Superficially resembling Claudopus variabilis, differing in the 

 persistently white gills. Differs from other small white species by 

 the thicker cap, gills radiating from the point of attachment, and by 

 the gills being first uppermost and then turned over. 



On wood, branches, twigs, decaying fungi, dung, etc. 



** Cap fleshy, striate, upper layer gelatinous. 



P. mastrucatus. — Cap at first resupinate, then expanded and 

 horizontal, often lobed, upper stratum gelatinous, brown, bristling 

 with erect squamules ; flesh thickish ; gills radiating from the point 

 of attachment, broad, rather distant, greyish white. 



Readily known by the brown, squarrosely scaly cap. 



On elm trunks. Imbricated or overlapping. 



P. atrocceruleus. — Cap at first resupinate, soon reflexed and 

 horizontal, obovate or reniform, downy, rarely almost smooth, 

 wrinkled when dry, usually blackish blue, rarely brownish, 1-2 in. 

 long, I in. broad ; flesh soft, upper layer slightly gelatinous, 

 rather thick, blackish brown, lower layer or flesh proper whitish ; 

 gills at first radiating from a point, then converging towards the 

 base, broad, whitish, at length tinged yellow. 



Smell very pleasant. Sessile, gregarious or imbricated. 



On rotten trunks of beech, poplar, etc. 



P. leightoni. — Cap rather thick, at first obliquely conical, umber, 

 then lead-colour, scurfy or bristly, upper layer gelatinous, about 

 I in. across ; gills radiating from the point of attachment of the cap, 

 rather thick, distant, tan-colour, somewhat wa\-y. 



On wood. 



P. rufiipes. — Cap dimidiate or reniform, thin, convex, very glu- 

 tinous when moist, white, disc salmon-colour, edge inturned, about 

 I in. diameter ; gills adnate, broad, distant, white ; stem becoming 

 recurved, viscous, reddish, base downy. 



On wood.
