Agaricus (Hypholoma) phyllogenus, Peck. 
Pileus firm, convex, sometimes slightly umbonate, hygrophanus, reddish- 
brown when moist, alutaceous when dry; lamellae plane, broad, close, brown, 
white on the edge; stem equal, fibrillose, stuffed or hollow, expanded at the 
base into a thin flat disk ; spores pale-brown, subglobose, .0002' in diameter. 
Plant 8’-12" high, pileus 2’—4” broad, stem .6” thick. 
Fallen leaves in woods. Worcester. July. 
This is a very small but distinct species, remarkable for the disk- 
like base of the stem by which it is attached to the leaves on which 
it grows. 
Coprinus variegatus, Peck. 
Pileus fleshy, fragile, oblong-ovate, then campanulate, obtuse, hygrophanous, 
pale watery-brown when moist, whitish or cream colored when dry, variegated 
by scales and patches of a superficial ochraceous tomentum, the margin finely 
striate ; lamellae lanceolate, crowded, ascending, free, white, then rosy-brown, 
finally black; stem equal, brittle, hollow, white, at first peronate-annulate, 
then floccose-pruinose, with white branching root-like threads at the base ; 
spores .00033' long. 
Plant densely caespitose, 3'-5' high, pileus 1'-1.5' broad, stem 2'—4” thick. 
Thin soil and decaying leaves covering rocks. Slope of Crows’ 
Nest near West Point. June. 
Allied to C. atramentarius. When young the whole plant is 
coated by an abundant superficial tomentum. This soon breaks up 
into loose scales or patches which peel off in flakes, revealing the 
smooth pileus beneath. The slight abrupt annulus soon vanishes. 
Coprinus insignis, Peck. 
Pileus campanulate, thin, sulcate-striate to the disk, grayish fawn-color, the 
smooth disk sometimes cracking into small areas or scales ; lamellae ascend- 
ing, crowded; stem hollow, slightly fibrillose, striate, white ; spores rough, 
.0004' x 00028’. 
Plant 4'-5' high, pileus 2'-3' broad, stem 3” thick. 
About the roots of trees in woods. Worcester. July. 
Coprinus angulatus, Peck. 
Pileus thin, hemispherical or convex, plicate-suicate, the disk smooth ; lam- 
ellae subdistant, whitish, then black; stem equal, smooth, whitish; spores 
compressed, angular, subovate, .0004' x .00083'. 
Plant 1'-2' high, pileus 6’-12” broad, stem .5’ thick. 
Woods. Croghan. September. 
The specific name has reference to the angular character of the 
spo res.
