A very distinct species, known by the dark colour of the 

 pileus and stem, both of which are sprinkled with, white 

 fibrils. 



Psilocybe areolata. Kotzsch, 



Pileus 1-3 in. across, convex, obtuse, then expanded, dry, 

 minutely fibrillose, cuticle breaking up into angular patches, 

 ochraceous or rufous, interstices and margin pale, yellowish ; 

 gills adnexed, 2-3 lines or more broad, umber then blackish. 

 with a purple tinge, margin whitish; stem 2-3 in. long, 

 2-3 lines thick, equal, attenuated or slightly thickened 

 below, fibrillose, dingy white, hollow ; flesh of pileus and 

 stem tinged brown ; veil fugacious ; spores blackish, umber 

 with a purple tinge, 12-13 x 8 yu.. 



Agaricus areolatus, Klotzsch, in Berk., Eng. Flor., vol. v. ; 

 Cke., Hdbk., p. 209 ; Cke., Illustr., pi. 590. 



In gardens, &c. 



Pileus |— 3 in. broad, convex, ochre or fuscous ; veil be- 

 tween fibrous and membranaceous, fugacious ; gills 2-3 

 lines broad, the edge white and beaded with drops of 

 moisture. Stem 2-3 in. high, generally thickened at the 

 hase, fibrillose, dirty white. (Klotzsch.) 



Densely caespitose. Pileus at first white, with the cuticle 

 entire, at length rufous and cracking into areolae, a much 

 firmer plant than A. sj)adiceus, not brittle. Stem striate, 

 pulverulent, especially towards the apex, hollow ; gills with 

 a distinct white edge, at first very pale, spores very dark, 

 almost black, broadly almond-shape. (W. G. Smith.) 



Psilocybe virescens. Massee. 

 Pileus 1-1 1 in. across, convex, obtuse, then becoming ex- 

 panded, when young minutely silky, bright dark brown, 

 during expansion the brown cuticle becomes broken up into 

 persistent angular patches, the interstices being clear pale 

 green, becoming yellowish with age ; gills adnexed, rather 

 crowded, 3 lines broad, soft, pallid then smoky purple, 

 margin pale ; stem about 2 in. long, 3 lines thick, equal, 

 smooth, apical portion pale green and strongly striate, 

 lower portion ferruginous, extreme base snow-white, downy, 

 firm, hollow, straight or slightly incurved ; spores sooty 

 purple, elliptical, ends obtuse, 9 x 5 /x.
