=A. spis´sa= Fr.—compact, dense;—of the warts. =Pileus= umber, sooty or gray, fleshy, somewhat compact, convexo-plane, obtuse, smooth, even, but _marked with small, ash-colored, angular, adnate_ warts; margin even, but often torn into fibers. =Flesh= _firm, white, quite unchangeable_. =Stem= 2–3 in. long, as much as 1 in. thick, _solid, turnip-shaped at the base_, somewhat rooting with a globoso-depressed not marginate bulb, curt, firm, shining white, at length _squamulose with concentric cracks_. =Ring= superior, large. =Gills= reaching the stem, _slightly striato-decurrent_, broad, crowded, shining white. _Fries._ =Spores= 14µ _W.G.S._; subglobose, 8–10µ _C.B.P._; 6µ _W.P._; rather pear-shaped, 9–10×6µ _Massee_. =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.
