Genus II. — Coprinds, Pers. 



LamelltE membranaceous, at first pressed together and coherent, 

 easily split, at length dissolving into a black fluid. Trama obsolete. 

 Spores black. 



Tribe I. Pellicolosi. — Pileus fleshy or membranaceous, not split- 

 tino- along; the back of the lamellae, but becoming torn and revolute. 



A. Stipe annulate. 



a. Pileus covered with broad scales, 1-3. , „.,> . , 



6. Pileus covered with minute scales, 4-6. .. . , -. 



B. Stipe not annulate. 



c. Pileus floccose, tomentose or villous, 7. >RDEN 



d. Pileus strewn with sparkling atoms, 8-10. 



A. Stipe annulate. 



a. Pileus covered with broad scales. 



1. C. coMATDs, Fl. D. — Pileus somewhat flesh}', cylindric, then 

 expanded, even, soon torn into broad, scattered, appressed scales. 

 Stipe hollow, fibrillose; the bulb solid, rooting; the annulus movable. 

 Lamellae free, linear, at first white, then changing to purple, finally 

 black. Spores somewhat oblique, apiculate, very large .015X-008 mm. 



On rich soil in pastures and grassy grounds. Solitar}- or gregarious;
