382 FUNGUS-FLORA. 



Agaricus (Pleurotus) Hobsoni, Berk., Outl., p. 139; Cke., 

 Hdbk., p. Ill; Cke., Illustr., pi. 212A. 



On stumps, branches, &c. 



Differs from P. applicatus in being much paler in colour, 

 and horizontal and plane, not cup-shaped. 



Pleurotus striatulus. Fr. 



Pileus 2-3 lines across, very thin, pale brownish grey, 

 more or less concave, flaccid, glabrous, striate, sessile ; gills 

 broad, few, distant, radiating from an excentric point, 

 greyish. 



Agaricus (Pleurotus) striatulus, Fries, Syst. Myc., i. p. 193; 

 Cke., Hdbk., p. Ill ; Cke., Illustr., pi. 212u, 



On fallen branches, wood, &c. 



Variable in form (-4.) obconically campanulate, pendulous 

 when growing on the under side of fallen trunks ; (B.) 

 imbricated, reflexed ; on branches of hazel; (C.) irregular; 

 on twigs. Becomes contracted when dry and escapes the 

 eye. (Fries.) 



Distinguished among the minute grey species by the 

 glabrous, striate pileus. 



Pleurotus hypnophilus. Berk. 



Pileus 24 lines across, very thin, resupinate, flat, white, 

 somewhat reniform, nearly smooth ; gills radiating from the 

 point of attachment of the pileus, narrow, distant, simple ; 

 spores elliptical, 5 x 3 //,. 



Agaricus (Pleurotus') hypnophilus, Berk., Outl., p. 139; Cke., 

 Illustr., pi. 212c; Cke., Hdbk., p. 111. 



On moss, fallen leaves, &c. 



Eesembling Claudopus variabilis closely in size and general 

 appearance, but the spores are white, and the gills do not 

 change colour. Distinguished among the small white species 

 of Pleurotus by the glabrous pileus. 



Exactly the habit of A. variabilis, but the spores are white, 

 and in consequence the gills do not change colour. (Berks.) 



Pleurotus chioneus. Pers. 



Pileus 23 lines across, very thin, partly resupinate, snow- 

 white, downy; stem lateral, very short, downy, at length 

 almost disappearing; gills radiating from an excentric point, 

 rather broad, with intermediate shorter ones, pure white.
