ICONES SeL. 137. 



Pileus fleshy, thin, convex then plane or depressed, smooth 

 and glabrous, hygrophanous, when wet dull ferruginous or 

 ochraceous, expallent when dry. Stipe nearly equal, fistulous, 

 scantily fibrillose, striate at the apex, nearly the same color at 

 the pileus. Lamellae narrow, close, adnate, often decurrent by 

 a tooth, pale-brown ; spores ferruginous-brown. 



Solitary or caespitose ; growing on old rotten trunks ; Pacific 

 Coast Cat. Pileus 3-5 cm. in diameter ; stipe 3-5 cm. long, 2-4 

 mm. thick. On account of the color of the spores Pries thought 

 the species might better be referred to Naucoria. 



15. PSILOCYBE LIMICOLA Peck, 24 N. ^. Rep. 1871. 

 Pileus thin, convex then expanded, smooth, .hygrophanous, 



dark watery brown and striatulate when moist, pale ochraceous- 

 brown when dry and rugulose. Stipe slender, equal, brittle, silky, 

 fistulous, whitish. Lamellae close, rounded behind, adnexed, 

 cinnamon-brown, becoming darker; spores elliptic, 10 mic. long. 

 Subcaespitose ; growing in damp muck soil in woods. New 

 York, Peck. Pileus 1-2.5 cm. in diameter; stipe 5 cm. long, 

 sacrcely 2 mm. thick. 



16. PSILOCYBE CERNUA, Agaricus cernuus, Vahl in 

 Flora Danica. Agaricus fasciculatus Schaeffer, Index. 



1774- 



Pileus fleshy campanulate then expanded, glabrous, hygro- 

 phanous, pallescent, white and rugulose when dry. Stipe slender, 

 fistulous, flexuous, glabrous, white, smooth and pruinose at the 

 apex. Lamellae rather narrow, subdistant. becoming ventricose, 

 adnate, whitish-cinereous then blackish-brown ; spores elliptic, 

 7-9 X 5-6 mic. 



Commonly caespitose ; growing on the ground among old 

 leaves and rotten wood. New York, Peck; Preston, O. Pileus 

 3-6 cm. in diameter; stipe 5-7 cm. long, 4-5 mm. thick. 



II. CALLOSAE. Pileus fleshy, mostly bright colored, 

 somewhat expallent, but scarcely hygrophanous or striatulate, in 

 wet weather the surface often slightly viscid. Stipe callous, 

 flexile, usually colored, glabrous or silky-fibrillose. 



a. Lamellae broad. 



17. PSILOCYBE ERTCAEA Persoon, Synopsis, 1801. 

 Fries, Icones Sel. 136. Cooke, Illustr. 568. 



Pileus fleshy, thin, conic then convex and explanate, smooth 

 and glabrous, slightly viscid when wet, shining when dry, ferru- 

 ginous or fulvous. Stipe elongated, tough, fistulous, pallid or 

 pale yellow, white-villous at the base. Lamellae broad, subdis- 

 tant, adnate, pallid then blackening; spores 8-10 x 5 mic.
