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 icith reddish or reddish- broton scales. 



12. A. ACUTESQUAJioscs, Weinui. — Pileus fleshy, obtuse, at first hirto- 

 floccose, then echinate, with erect acute squarrose scales. Stipe stout, 

 bulbous. Lamelloe approximate, lanceolate, simple. Spores with a 

 nucleus on one side, oblong .0042X-0028 mm. 



In woods in rich soil about old stumps. Pileus 2-3 in. broad, red- 

 dish-brown, with darker stjuarrose scales; the stipe 3-4 in. high, the 

 bulb sometimes with a crenate margin. Veil clinofino- to the margin 

 of the pileus, and finall^^ forming an ample annulus. Our plant seems 

 to differ from the European one, especially in the nature of the bulb.

 nate; cuticle reddish, fibrose-lacerate. Stipe hollow, glabrous, some- 

 what bulbous, tapering upward; annulus persistent. Lamellae free, 

 white. 



Among the old leaves in rich woods. Pileus 1^-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 breaks up into silky 

 fibres, which commonly remain. 



14. A. AMERiCANDS, Pcck. — Pilcus couvcx, umbonatc ; tho margin 

 obscurely striate. Stipe glabrous, gradually enlarged below into a 

 long sub-ventricose bulb-like base. Lamellai 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 dr^ang 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 broivn scales. 



15. A FUSCosQUAMEUs, Pcck. — Pilcus convex, rough with erect point- 

 ed blackish brown scales. Stipe floccose, thickened at the base. 

 LamelliC free, white. Spores .0076X-0036 mm. 



In rich woods among the leaves. Pileus li^-2 in. broad, stipe 2-3 in. 

 long. All parts of the plant somewhat whitish at first turn black in 

 handling.
