136. A VELUTiNUS, Pers. — Pileus somewhat fleshy, campanulate, 

 then expanded, at length obtusely umbonate, even, at first tomentose, 

 with appressed fibrils, afterward becoming glabrous, hygrophanous ; 

 the flesh very thin, concolorous. Stipe hollow, fibrillose-silky, sordid- 

 argillaceous. Lamellae seceding, rather close, brown, black-punctate. 



In the streets of the suburbs, along the country roads, etc. Size

 convex, explanate, obtuse, glabrous, hj'grophanous. Stipe hollow, 

 fragile, somewhat flbrillose, white, striate at the apex. Lamellae ro- 

 tundate-attached, close, violaceous then brown-cinnamon. Spores 

 brown, oblique, .0090X.00r)6 mm. 



On the ground in woods. Pileus 1^-3 in. in diameter, stipe 1-^-3 in. 

 high. The colors even of the lamellae seem to be exceed ingl}' variable; 

 the pileus is commonly cinereous or whitish, darker in the center. 



138. A. APPENDicuLATUs, Bull. — Pileus fleshy-membranaceous, 

 ovate-expanded, glabrous, hygrophanous, when drj- rugose and 

 somewhat atomate. Stipe hollow, equal, glabrous, white, pruinate at 

 the apex. Lamellte somewhat adnate, close, dry. whitish then fleshy- 

 brown. Spores .005X. 004 mm. 



Upon trunks especially of beech. Densel}^ caespitose; pileus 2-3 in. 

 broad, stipe 3 in. in length. Pileus brownish then tawn}^ or pale ochre; 

 the flesh .if the same color. 



Subgenus XXVIII. — Psilocybe. 



Pileus more or less fleshy, glabrous; the margin at first incurved; 

 the veil none. Stipe somewhat cartilaginous. 



139. A. SPADiCEUS, Fr. — Rigid. Pileus fleshy, convexo-plane, obtuse, 

 even, moist, hj-grophanous. Stipe hollow, tough, pallid, even at the 

 apex. Lamellae rotundate-attached, dry, close, whitish then fleshy- 

 brown. Spores elliptic, purplish-brown, .0076x.0051 mm. 



In grassy grounds of doorj'ards, lawns and fields, very abundant 

 after rains, in spring and summer. Pileus 1^-3 in. broad, stipe 2-3 in. 

 long. Pileus even, at first glabrous, rigid, scabrous, umber-brown, be- 

 coming pale when dry; the flesh whitish; the margin inflexed, often
