PSILOCYBE. 375 



At roots of ash in damp places. 



Yar. polycephalus, densely crowded, more rigid, stems 

 thinner, flexuose ; gills almost free, at length nmber-hrown. 



Paulet, t. iii. figs. 1-2 ; Pries, Hym. Eur., p. 302 ; Cke., 

 Hdbk., p. 212. 



On trunks. 



Colour as in the typical form, hay then ochraceous, or 

 pallid-li^'id then clay-colour. 



At the base of trunks, amongst leaves, &c., very common. 

 Very distinct from Bypholoma appendtculatum, which it 

 approaches in colour, in the more rigid pileus and stem, and 

 in the complete absence of a veil. Known from every other 

 species of the present genus in the gills being white then 

 flesh-colour, and finally brown. In size and other points 

 very variable. Typically large, terrestrial, forming large, 

 loose clusters. Stem firm, subcartilaginous, hollow, 3—4: in. 

 long, 3-5 lines thick, equal, often curved, glabrous, white, 

 apex not striate. Pileus fleshy, convex then plane, obtuse, 

 3-4 in. broad, even, glabrous, moist in wet weather but not 

 viscid, umber-brown, becoming pale when dry, often cracked 

 and torn, margin inflexed when young. Gills rounded- 

 adnexed, crowded, dry, white, then flesh-colour, at length 

 umber. (Fries.) 



Psilocybe squalens. Fr. 



Pileus 1-2 ia. across, rather fleshy, convex then plane or 

 depressed, even, glabrous, moist, hygrophanous, lurid then 

 pale; gills adnato-decurrent, crowded, plane, clay-colour 

 then brown; stem about 2 in. long and 2 lines thick, equal, 

 not rooting, apex striate, nearly like the pileus in colour, 

 stuffed. 



Agaricus (Psilocybe) squalens. Fries, Epicr., p. 226 ; Fries, 

 Hym. Eur., p. 303. 



On and near trunks. 



Solitary or tufted. Veil absent. Stem 1-2 in. long, 1-2 

 lines thick, tough, obsoletely fibriUose. Pileus 1-2 in. across, 

 lurid then pale, margin incurved. Spores rusty-brown. 



Eesembling Psilocybe cernuvs, but quite distinct in the 

 brownish-ferruginous spores, hence technically belonging to 

 the Ochrosporae ; veil none. Stem stuffed then hoUow, not 

 very rigid, not rooting, about 2 in. long, 2 lines thick, equal,
