=A. monticulo´sa= Berk.—mountain, from the warts. =Pileus= 2.5–3 in. across, convex, areolate, with a wart in the center of each areola; those toward the margin consisting of soft threads meeting in a point, but sometimes simply flocculent, the central warts angular, pyramidal, truncate, discolored. =Stem= bulbous, scaly, flocculent, white. =Veil= thick, at length distant. =Gills= free, ventricose, remote, forming a well-defined area around the top of the stem. The warts are not hard and rigid as in A. nitida, and the free remote gills separate it from that and the neighboring species. _Berk._ North Carolina, sandy woods, common. _Curtis._ Properties not known. =A. dau´cipes= B. and M.—_daucum_, a carrot; _pes_, a foot. =Pileus= 2–5 in. broad, hemispherical, globose. =Flesh= white, soft, warts regular, pyramidal, saffron color. =Gills= narrow, reaching the stem, broadest in the middle. =Stem= 5–6 in. high, solid, base bulbous, with a restricted cortina above, squamulose downward. =Veil= fibrillose, extending from the margin of the pileus to the apex of the stem, fugacious. In cultivated fields. Ohio. _Sullivant._ Properties not given. =A. lenticular´is= Lasch.—resembling (the stem) a lentil. Fries places this species in Amanita, in which Stevenson follows him. Cooke and Massee place it in Lepiota, where it will be found. **** _Volva rudimentary, wholly disappearing._ =A. chlorinos´ma= Pk.—smelling like chlorine. (Plate VIII, fig. 1, p. 18.) =Pileus= convex or expanded, warty on the disk, covered on the even margin with a light powdery, at length evanescent substance, white. =Gills= white. =Stem= nearly cylindrical, stout, deeply penetrating the earth. =Spores= broadly elliptical, 7–10µ long. Odor distinct, chlorine-like. =Plant= 6–7 in. high. =Pileus= 4–6 in. broad. =Stem= 1–2 in. thick. _Peck_, Bot. Gaz., Vol. 4. Burnt ground in woods. August. Closter, N.J., _C.F. Austin_; Alabama, _U. and E._; West Virginia, _Nuttall_; New Jersey, _Ellis_; Mt. Gretna, Pa., July, in a cluster of a dozen individuals, and afterward until frost, strong smelling, warts brownish-white. _McIlvaine._ It is edible and equal to A. strobiliformis. =A. calyptra´ta= Pk. =Pileus= fleshy, thick, convex or nearly plane, centrally covered by a large irregular persistent grayish-white fragment of the volva, glabrous elsewhere, striate on the margin, greenish-yellow or yellowish-brown tinged with green, the margin often a little paler or more yellow than the rest. =Lamellæ= close, nearly free, but reaching the stem and forming slight decurrent lines or striations on it, yellowish-white tinged with green. =Stem= stout, rather long, equal or slightly tapering upward, surrounded at the base by the remains of the ruptured volva, white or yellowish white with a faint greenish tint. =Spores= broadly elliptic, 10µ long, 6µ broad, usually containing a single large nucleus. =Pileus= 10–20 cm. broad. =Stem= 10–15 cm. long, 12–20 mm. thick.
