* Stem excentric. 



** Stem distinctly lateral. 



*** Stem absent ; pileus resupinate 



* Stem excentric. 



Panus conchatus. Fr. 



Pileus about 3 in. across, tough and flexible, unequal, ex- 

 centric or dimidiate, margin often lobed, cinnamon-colour 

 becoming pale, at length more or less scaly ; flesh thin ; 

 gills narrow, forming decurrent lines on the stem, some- 

 what branched; pinkish -white then pale-ochraceous, stern

Panus conchatus, Fries, Epicr., p. 398 ; Cke., Hdbk., p. 357 ; 

 Cke., Illustr., pi. 1149 A. 



On trunks of beech, poplar, &c. 



Often imbricated and more or less grown together. Allied 

 to Panus torulosus, but distinguished by the much thinner 

 pileus, more expanded and excentric, also dimidiate, flaccid, 

 cinnamon becoming pale, but. the form not constant. Stem 

 about \ in. long, 4 lines thick, often compressed, downy at 

 the base. Pileus 2-4 in. broad, scaly when old. Gills de- 

 current in long, parallel lines, not at all resembling those of 

 Pleurotus ostreatus, which anastomose behind, but frequently 

 unequally branched, at first whitish or pale flesh-colour, 

 then wood-colour, crisped when dry. (Fries.) 



Panus torulosus. Fr. 



Pileus 23 in. across, coriaceous and flexible, plane, in- 

 fundibuliform, or.dimidiate, margin often much waved, even, 

 somewhat flesh-colour then ochraceous, not scaly ; flesh thin ; 

 gills decurrent; narrow, rather distant; not anastomosing 

 behind; ruddy then pale buff; stem i 1 in. long, 35 lines
