Leucosporae 



Plant 2-3 in. high. PileilS 1.5-2 in. broad. Stem 3-5 lines thick. Amanita. 

 Grassy ground in open woods. Greenbush. June. 



This species is remarkable for the thin striate-tuberculate margin of 

 the pileus, which causes it to resemble some species of Russula. Peek,

Massachusetts, Francis. 



A. strobilifor mis Vitt. strobilis, a pine-cone, from the shape of 

 the warts. (Plate VIII, fig. 3, p. 18.) Cap 3-10 in. across, convex 

 or nearly plane, white or cinereous, sometimes yellow on the disk, 

 rough with angular, mostly persistent warts which sometimes fall away 

 and leave the pileus nearly smooth ; generally whitish, sometimes tinged 

 with brown; the margin even and extending a little beyond the lamellae. 

 Grills free, rounded behind. Veil large and portions sometimes adhere 

 to margin of cap. .Stem 3-8 in. long, up to i M in. thick, equal or 

 slightly tapering upward, solid, floccose-scaly, white, bulbous, the bulb 

 very large, sometimes weighing a pound, margined above and furnished 

 with one or two concentric furrows, somewhat pointed below, firmly 

 and deeply imbedded in the earth, floccose-mealy when young. 



Spores elliptical, 13-15x8-10^. Peck. 



Open woods and borders. June to October. 



Edible. W. G. Smith, Curtis, Peck. 



This is among the best of species. Its size, solidity, flavor are 

 marked. I have found .specimens weighing a pound and a half. It 

 grows singly, but when one is found several are apt to be neighbors. 

 When young, the cap is but a small knob upon a beet or top-shaped 

 base, which is largely under ground. It cuts like a soft turnip, and has 

 a strong, pungent, unmistakable odor, like chloride of lime, which en- 

 tirely disappears in cooking. As the plant develops the bulb decreases 

 in size. On all the many specimens the author has seen and eaten, the 

 scabs are light brown and reddish-brown. 



A. SOlita'l'ia Bull. growing alone. PileilS convex or plane, warty, 

 white or whitish, even on the margin. Grills reaching the stem, white 

 or slightly tinged with cream color. Stem at first mealy or scaly, equal, 

 solid, white, bulbous, the bulb scaly or mealy, narrowed below into a 

 root-like prolongation. Ring' lacerated, often adhering in fragments to 

 the margin of the pileus and gills. Spores elliptical-oblong, 8-13x6.5^.
