364 FUNGUS-FLOKA. 



The total absence of the partial veil from the first 

 separates the species included in the present section from 

 those of Agaricus and Hypholoma, which they otherwise 

 much resemble. 



I. TENACES. Veil accidental, rarely conspicuous, Pileus 

 pelliculose, often rather viscid when moist, becoming pale. Colour 

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

 * Gills ventricose, not decurrent. 



Psilocybe sarcocephala. Fr. 



Pileus 24 in. across, fleshy, compact, convex, obtuse, be- 

 coming expanded and sometimes depressed in the centre, 

 even, dry, pale tawny becoming pale, the margin sometimes 

 whitish ; gills adnate, very broad, (3-4 lines), not crowded, 

 greyish flesh-colour, then sooty from the dark spores ; stem 

 35 in. long, 24 lines thick, subequal, usually curved or 

 flexuous, whitish, apex powdered with white meal, stuffed 

 then hollow ; spores elliptical, dull brown, 7 X 3 5 p.. 



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. Stem robust, stuffed then hollow, elongated, 

 curved, equal or slightly thinner below, 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. 

 long, 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 fleshy, rather firm, convex then ex- 

 panded, obtuse, 3-4 in. broad, the smallest 12 in., even, 

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

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

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

 then rather fuliginous from the spores. (Fries.)
