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

 Hdbk., p. Ill; Cke., lUustr., pi. 212a. 



On stumps, branches, &o. 



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

 and horizontal and plane, not oup-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. 198; 

 Cke., Hdbk., p. Ill ; Cke., lUustr., pi. 212b, 



On fallen branches, wood, &c. 



Tariable in form (J..) obconioally campanulate, pendulous 

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

 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 2—4 lines across, very thin, resupinate, iiat, white, 

 somewhat reniform, nearly smooth ; gills radiating from the 

 j)oint of attachment of the pUeus, narrow, distant, simple ; 

 spores elliptical, 5 X 3 /x. 



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 2-3 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, Avith intermediate shorter ones, pure white.
