1. P. conchatus Fr. Pileus 5-10 cent. (2-4 in.) broad, cin- 

 namon then becoming pale, fleshy-plian t, thin, unequal, excentric, 

 even dimidiate, flaccid, squamulose 

 when old. Stem about 12 mm. (}4 

 in.) long, 8 mm. (4 lin.) thick, un- 

 equal, often compressed, pubescent at 

 the base. Gills deeply decurrent in 

 parallel lines, by no means anasto- 

 mosing, but here and there branched 

 and unequal, at first whitish or pale 

 flesh-colour, at length ochraceous- 

 wood-colour, crisped when dry. 



Cosspitose, often imbricated and grow- 

 ing into each other. No form is constant. 

 So much allied to P. torulosus that the real 

 difference is not apparent. It is thinner, 

 more conchate and more lobed than that 

 species. 



On trunks. Rare. June-Oct. 



L V. Panus torulosus. One-fourth 

 natural size.

2. P. torulosus Fr. Pileus 5-7.5 cent. (2-3 in.) broad, some- 

 what flesh-colour, but varying rufescent - livid and becoming 

 violet, entire, but very excentric, fleshy, somewhat compact when 

 young, plano-infundibuliform, even, smooth ; flesh pallid. Stem 

 short, commonly 2.5 cent, (i in.), solid, oblique, tough, firm, com- 

 monly with grey, but often violaceous down. Gills decurrent, 

 somewhat distant, simple, separate behind, reddish then tan- 

 colour. 



Very changeable in form, at first fleshy-pliant, at length coriaceous. In 

 the covering of the stem it approaches Paxillus atro-tomentosus, but there is 

 no affinity between them. 



On old stumps. Frequent.
