3 in. high; the margin in my figure is thin and striate; the color is 
white, with a sordid or alutaceous cuticle seceding up to the conspicu- 
ous umbo. 
b. Annulus fixed. 
c’. Pileus with reddish or reddish-brown scales. 
12. A. acuTEsQuAMosus, Weinm.—Pileus fleshy, obtuse, at first hirto- 
floccose, then echinate, with erect acute squarrose scales. Stipe stout, 
bulbous. Lamelle approximate, lanceolate, simple. Spores with a 
nucleus on one side, oblong .0042>.0028 mm. 
In woods in rich soil about old stumps. Pileus 2-3 in. broad, red- 
dish-brown, with darker squarrose scales; the stipe 3-4 in. high, the 
bulb sometimes with a crenate margin. Veil clinging to the margin 
” of the pileus, and finally forming an ample annulus. Our plant seems 
to differ from the European one, especially in the nature of the bulb. 
13. A. RUBRO-TINOTUS, Peck.—Pileus fleshy, soft, convex, then expla- 
nate; cuticle reddish, fibrose-lacerate. Stipe hollow, glabrous, some- 
‘what bulbous, tapering upward; annulus persistent. Lamelle free, 
white. f 
Among the old leaves in rich woods. ‘Pileus 14-3 in. broad, stipe 3-4 
in. long. This is a very beautiful plant; the pileus is bright red, and 
the stipe white, smooth and shining, the cuticle bredks up into silky 
fibres, which commonly remain. 
14, A. AMERICANUS, Peck.—Pileus convex, umbonate ; the margin 
obscurely striate. Stipe glabrous, gradually enlarged below into 4 
long sub-ventricose bulb-like base. Lamelle free. 
On lawns and elsewhere on grassy grounds. Pileus 2-3 in. broad, 
stipe 3-4 in. high. The whole plant when handled or in drying changes 
to a dull pinkish-red color. The frail annulus is sometimes carried 
away upon the margin of the pileus. 
d’. Pileus with blackish or blackish-brown scales. 
15, A FuscosquAMEus, Peck.—Pileus convex, rough with erect point- 
ed blackish-brown scalés. Stipe floecose, thickened at the base. 
Lamelle free, white. Spores .0076.0036 mm. 
In rich woods among the leaves. Pileus 14-2 in. broad, stipe 2-3 in. 
long. All parts of the plant somewhat whitish at first turn black in 
handling. 
16. A, FELINUS, Pers.—Pileus fleshy, thin, the umbo and the scales
