Cap 2–3 in. across. Stem 2½-3 in. long, up to ¾ in. thick.
New Jersey, oak woods, August and September. McIlvaine.
A. spissa has been reported from but few localities. It is rare in the latitude of Philadelphia. Half a dozen specimens have been found in neighboring New Jersey.
Taste and smell strong, but when cooked the dish is savory and not unlike one of A. rubescens.
A. as´pera Fr.—asper, rough. Pileus 2–3 in. across. Flesh rather thick at the disk, whitish, white or reddish with tints of livid or gray, reddish or brownish under the cuticle; convex then plane, margin thin and even, rough with firmly adnate, minute, closely crowded, angular warts, reddish-brown or livid-brownish, not pure white, unchangeable. Gills free and rounded behind, not striately decurrent, ventricose, white. Stem stuffed, striate above the ring, short at first, ovate, then elongating to 2–3 in., attenuated upward from a wrinkled bulb, squamulose, white without and within. Ring superior, entire.
Spores 8×6µ Massee; 8×6–7µ W.G.S.
The flesh of stem and bulb when eaten by insects is reddish, the bulb when old is a reddish-brown. The large ring and stem become red when touched. In these particulars it resembles A. rubescens. In smell it is somewhat strong, not unlike A. strobiliformis, but not nearly so pungent.
Cooked it is of excellent quality and flavor. I have eaten it since 1885.
A. abrup´ta Pk.—abrupt, of the bulb. Pileus thin, broadly convex or nearly plane, covered with small angular or pyramidal, erect, somewhat evanescent warts, white, slightly striate on the margin. Flesh white. Gills moderately close, reaching the stem and sometimes terminating in slightly decurrent lines upon it, white. Stem slender, glabrous, solid, bulbous, white, the bulb abrupt, subglobose, often coated below by the white persistent mycelium, the ring membranous, persistent. Spores broadly elliptical or subglobose, 8–10×6–8µ.
Pileus 2–4 in. broad. Stem 2.5–4 in. long, 3–4 lines thick.
