The total absence of tlie partial veil from the first 

 separates the species inchidfd iu the present section from 

 those of Agaricus and Hi/jiholoma, which they otherwise 

 much resemble. 



I. TENACES. Veil accidental, rarely conspicuous, Pileus 

 pellicnlosc, often rather viscid ichen moist, becoming pale. Colour 

 of pileus bright. Stem hard, flexile, often coloured. 



* Gills ventricose, not decurrent. 



Psilocybe sarcocephala. Fr. 



Pileus 2—4 in. across, fleshy, compact, convex, obtuse, be- 

 coming expanded and sometimes depressed in the centre, 

 even, drj-, pale tawny becumiiig pale, the margin sometimes

Agaricus (^Psilocybe) sarcocephalus. Fries, Monogr. 1, p. 429, 

 (not of Epicr. !) ; Hym. Eur., p. 297 ; Cke., Hdbk., p. 208 ; 

 Cke., Illustr., pi. 567 and 520. 



Grassy places, especially about stumps. Solitary or clus- 

 tered. Distinct from every other species in the fleshy, com- 

 pact pileus. 



In every respect the noblest and most distinct species 

 belonging to the present genus, not related to any other 

 species. Gregarious, subcaespitose ; without the slightest 

 trace of a veil. 8teni rol)ust, stuffed then hollow, elongated, 

 curved, equal or slightly thinner beloAv, whitish, sometimes 

 with a rusty tinge, powdered with white meal at the apex, 

 slightly squamulose, in other respects glabrous. In clus- 

 tered individuals the stem is wavy and thinner, 3 in. 

 Jong, 2-3 lines thick ; in the larger form, not caespitose, 

 the stem is stouter, straight, 3-4 in. long, up to 1 in. 

 thick. Pileus truly flesh}-, rather firm, convex then ex- 

 panded, obtuse, 3-4 iu. broad, the smallest 1-2 in., oven, 

 glabrous, dry, pale ferruginous. Flesh white, unchangeable, 

 firm, not tough. Gills adnate, in the large form J in. broad, 

 ventricose, rather thick, not crowded, greyish flesh-colour,
