rous, expallent; the margin thin. Stipe stuffed then hollow, rigid, 
scaly-squarrose, ferruginous-blackish downward. Lamelle adnate- 
decurrent, clos2, rather broad, pallid then cinnamon. Spores brown- 
ferruginous, .011yv.007 mm. 
Upon stumps and fallen trunks, rarely upon the ground. Czspitose; 
pileus 13-24 in. in breadth, stipe 2-3 in. long, though the plant as its 
name indicates is quite variable in size and appearance. Pileus cinna- 
mon, becoming pale when dry, commonly more or less umbonate and ir- 
regular. The stipe in my figures is rather smooth. 
100. A. marGinatus, Batsch.—Pileus a little fleshy, convexo-expand- 
ed, glabrous, moist, hygrophanous; the margin striate. Stipe hollow, 
soft, not scaly, pruinose above the fugacious annulus; the base darker, 
white-velvety. Lamelle adnate, close, narrow, watery cinnamon. 
On ground and wood in a damp ravine; in spring. Pileus 1-14 in. 
across, stipe about 2 in. long. Ofa watery substance; the veil often 
curtained; the stipe somewhat fibrillose or striatulate. Color watery- 
cinnamon, changing to alutaceous or whitish. 
101. A. unicoLor, Fl. D.—Pileus a little fleshy, campanulate then 
convex, somewhat umbonate, glabrous, rather even, hygrophanous. 
Stipe stuffed then hollow, nearly glabrous, concolorous; the annulus 
thin, entire. Lamelle adnate-seceding, broad, somewhat triangular, 
ochraceous-cinnumon. Spores ferruginous, oblong ovoid, .0076X.0056 
mm. 
On fallen trunks and branches in woods, especially along the damp 
ravines; in autumn. Ceespitose or solitary; pileus about 1 in. in di- 
ameter, stipe about 1 in. long. This little plant is very abundant; it 
is well marked by its regular shape, smooth surface and persistent 
annulus. The color is a brownish, ferruginous, drying to paler or 
ochraceous.
