stipe 4-8 in. high, though these dimensions are sometimes greatly ex- 
ceeded. The pileus varies much incolor, being brownish, ochraceous, 
pallid and even whitish; it is at first slimy. The stipe is sometimes 
_ twisted, and in the variety which most commonly grows with us, the 
stipe is furfuraceous with minute scurfy particles. 
44, A. pLATYpHYyLLUs, Pers.—Pileus fleshy-membranaceous, ex- 
planate, obtuse, moist, fibrillose-virgate. Stipe stuffed, equal, soft, 
naked, striate, pallid; the root premorse. Lamelle truncate-attached, 
distant, very broad, white. Spores, .v18x.013 mm. 
In woods, on and about rotten logs, common from spring to autumn. 
Pileus 4-7 in. across, stipe 3-5 in. high, and 4-2 in, thick. The pileus 
is watery, and varies in color from brownish and cinereous to whitish; 
it is sometimes quite wavy and irregular. The stipe is white, very 
stout and biunt at the base, with an abundant white mycelium. Ours 
may be the variety repens figured by Fries in his “ Icones Selecte;” I 
find the stipe sometimes hollow. 
6. Lamelle narrow, close. 
45, A. BuTYRACEUS, Bull.—Pileus fleshy, convexo-expanded, umbon- 
ate, even, glabrous, moist, expallent, the flesh becoming white. Stipe 
somewhat stuffed, cartilaginous-corticate, conic, striate, dark reddish. 
Lamellz nearly free, close, crenulate, white. Spores .0076.0050 mm. 
In woods, not common. Pileus 2-3 in. broad, stipe 24-34 in. high. 
The color of the pileus exceedingly changeable, normally reddish or 
brownish, then passing through ochraceous or alutaceous to pallid or 
whitish. The stipe often twisted and downy or villous at the thick- 
ened base. Our figure and specimens agree well with the figures of the 
species in Dr. Cooke’s illustrations. 
46. A. pryopHitus, Bull.—Pileus somewhat fleshy, rather plane, ob- 
tuse, somewhat depressed, even, glabrous, expallent. Stipe hollow, 
glabrous, reddish or yellowish. Lamelle sinuate-attached, nearly free, 
close, narrow, white or pallid. Spores .006 mm. in length. 
Common in woods from early spring to autumn. Pileus 1-2 in. broad, 
stipe 2-3 in. high. Pileus commonly reddish-brown, sometimes paler, 
of a watery substance, and easily detached from the stipe. Stipe 
of the same color as the pileus, very smooth, often mycelio-enlarged 
at the base. 
47, A. ESTENSIS, n. sp.—Pileus a little fleshy, conic-campanulate, then 
depressed or even revolute, yellowish, with a pallid margin. Stipe
