Genus I].—Corrinus, Pers. 
Lamelle membranaceous, at first pressed together and coherent, 
easily split, at length dissolving into a black fluid. Trama obsolete. 
Spores black. 
-TriseE I, Petiicutosi.—Pileus fleshy or membranaceous, not split- 
ting along the back of the lamellez, but becoming torn and revolute. 
A. Stipe annulate. 
a. Pileus covered with broad scales, 1-3. 
b. Pileus covered with minute scales, 4-6. 
B. Stipe not annulate. 
c. Pileus floccose, tomentose or villous, 7. 
d. Pileus strewn with sparkling atoms, 8-10. 
A, Stipe annulate. 
a. Pileus covered with broad scales. 
1. C. comatus, Fl. D.—Pileus somewhat fleshy, cylindric, then 
expanded, even, soon torn into broad, scattered, appressed scales. 
Stipe hollow, fibrillose; the bulb solid, rooting; the annulus movable. 
Lamellee free, linear, at first white, then changing to purple, finally 
black. Spores somewhat oblique, apiculate, very large .015.008 mm. 
On rich soil in pastures and grassy grounds. Solitary or gregarious; 
pileus 2-4 in. high and 13-3 in. in diameter; stipe 6-12 in. in height, 
and 4-2 in. thick. The largest and most showy of the genus. Pileus 
sordid whitish or verging into lilac, in the larger specimens densely 
shaggy with the broad fibrillose cinereous or brownish scales. Stipe 
white or pinkish; the annulus sometimes volvaceous and persistent at 
the base of the stipe, sometimes clinging at various heights upon the 
stipe or dropping off. Lamelle beautifully variegated with pink and 
brown and black. Finally the whole pileus becomes a revolute, torn 
and fragmentary dripping mass of black inky fluid and spores, staining 
the stipe and herbage. 
2. C, sQuamosus, n. sp.—Pileus somewhat. membranaceous, ovoid 
then expanded, cinereous, covered with reddish-brown scales. Stipe
