gin; the cuticle separated into brownish, floccose scales. Stipe 
slender, attenuated downwards, brown like the pileus; the an¬ 
nulus persistent about the middle of the stipe. Lamellae broad, 
distant, ventricose, free; the spores about io mic. long. 
Gregarious; growing on rich soil in gardens. S. Carolina, 
Ravenel. Pileus 1-2 cm. in diameter, the stipe 2-2.5 cm. in length 
and not 1 mm. thick. It is desirable that the species be identified 
and better described.

Pileus fleshy, ovoid then campanulate and expanded, sub- 
umbonate; the flesh thin, white; the dermis radiately fibril- 
lose, white beneath the cuticle, cuticle tawny-brown, darker in 
the center, at maturity slightly parted into minute scales, the 
fibers on the umbo often acutely convergent; the veil flocculose, 
partly appendiculate. Stipe subequal above the mycelial bulb, 
fistulous, fibrous-stuffed, white and smooth above the annulus, 
below floccose-fibrillose and rufescent, with scattered tawny 
scales. Lamellae rather narrow, close, white, rounded behind, 
free, approximate; spores elliptic-oblong, obliquely apiculate, 
5- 6 x 3 mic. 
Growing on the ground in woods, Preston, Ohio. Pileus

blackish cuticle, which is soon broken up and drawn apart into 
small scales. Stipe long, slender fibrillose-floccose, brown or 
blackish; the annulus membranaceous, persistent, blackish on the

broadly elliptical, 6-7 x 4 mic. 
Growing in rich soil in woods, Canada, Dearness. Pileus 
6- 10 mm. in diameter, the stipe 2-3 cm. long and about 1 mm.

ering upward from a clavate base, fistulous, the cuticle whitish 
above, blackened and scaly below; the annulus thin membrana¬ 
ceous, deciduous. Lamellae rather narrow, close, free, white; 
spores elliptic-ovoid, 6-8 x 4-5 mic. 
Growing on the ground in woods. New York, Peck; Wis¬ 
consin, Denniston: Preston, O. Pileus 3-5 cm. in diameter; the
