=A. adna´ta= (W.G.S.) Roze—_adnatus_, adnate, of the gills. =Pileus= about 3 in. across. =Flesh= thick, whitish, firm, convex, then expanded, rather moist, pale yellowish-buff, often furnished with irregular, woolly patches of volva; margin even, extending beyond the gills. =Stem= 2–4 in. long, ½ in. thick, cylindrical, rough, fibrillose, pale buff, flesh distinct from that of the pileus, stuffed, then hollow; base slightly swollen. =Volva= adnate, white, downy, margin free and lax, sometimes almost obsolete. =Gills= truly adnate, crowded, with many intermediate shorter ones, white. =Spores= subglobose, with an oblique point, 7–8µ _Massee_. Tender, good flavor, yielding more substance when cooked than any other Amanitopsis. =A. volva´ta= Pk.—possessing a volva. =Pileus= convex, then nearly plane, slightly striate on the margin, hairy or floccose-scaly, white or whitish, the disk sometimes brownish. =Gills= close, free, white. =Stem= equal or slightly tapering upward, stuffed, minutely floccose-scaly, whitish, inserted at the base in a large, firm, cup-shaped, persistent volva. =Spores= elliptical, 10×8µ. =Plant= 2–3 in. high. =Pileus= 2–3 broad. =Stem= 3–4 lines thick. _Peck_, 33d Rep. N.Y. State Bot. The plant is easily recognized by its large, cup-shaped volva and cap, which is not smooth, as is usual in a species with a persistent membranous volva, more or less scaly with minute tufts of fibrils or tomentose hairs. The gills are white in the fresh plant. Professor Peck notes the species as quite rare. Numerous specimens occur in the sandy oak woods of New Jersey, and in oak woods near Angora, Philadelphia. July to October. Care must be taken to determine the absence of an annulus or any trace of one. Tender, delicate, without pronounced flavor. Equal to Amanitopsis vaginata. =A. farino´sa= Schw.—covered with _farina_, meal. =Pileus= nearly plane, thin, _flocculent-pulverulent, widely and deeply striate on the margin_, grayish-brown or livid-brown. =Gills= free, whitish. =Stem= whitish or pallid, equal, stuffed or hollow, mealy, _sub-bulbous_, the volva _flocculent-pulverulent_, evanescent. =Spores= variable, _elliptical ovate or subglobose_, 6–8µ long. =Plant= about 2 in. high. =Pileus= 1 in. to 15 lines broad. =Stem= 1–3 lines thick. July to September. This is our smallest Amanita (now Amanitopsis). It is neither very common nor very abundant when it does occur. It is described by Schweinitz as “solid,” but I have always found it stuffed or hollow. _Peck_, 33d Rep. N.Y. State Bot. =A. pusil´la= Pk.—small. =Pileus= thin, broadly convex or nearly plane, subglabrous, slightly umbonate, even on the margin, pale brown. =Gills= narrow, thin, close, free, becoming brownish. =Stem= short, hollow, bulbous, the bulb margined by the remains of the membranous volva. =Spores= broadly elliptical, 5–6×4µ. =Pileus= about 1 in. broad. =Stem= 8–12 lines long, 1–2 lines thick.
