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 lamellæ. Gills free, rounded behind. Veil large and portions sometimes adhere to margin of cap. Stem 3–8 in. long, up to 1¼ 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, 13–15×8–10µ 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 entirely 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´ria Bull.—growing alone. Pileus convex or plane, warty, white or whitish, even on the margin. Gills 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, 8–13×6.5µ.

Plant 4–8 in. high. Pileus 3–6 in. broad. Stem 4–6 lines thick. Peck, 33d Rep. N.Y. State Bot.

Solitary in woods and open places. July to October.
