Ground in open places. Sandlake and Gansevoort. August. _Peck_, 32d Rep. N.Y. State Bot. This is a dangerous species, because containing a deadly poison and resembling the most common forms of Amanitopsis, therefore likely to be mistaken for them. Specimens sent by me to Professor Peck were identified as his species. I add my own description. =Pileus= oval, broadly umbonate, date-brown toward and on umbo, soft, dry, smooth, more or less sulcate on edge. =Flesh= white, thin, except at center. =Stem= tapers rapidly above ring and at base, white-reddish-brown toward middle, narrows toward volva from which it is almost free at the base, hollow, furfuraceous above ring. =Gills= white, crowded, free. =Ring= white, thin, persistent, but at times hard to distinguish because clinging to stem. =Volva= free, fitting close, upper margin thin, lower part quite thick, making stem appear bulbous, which it is not. White forms occur. Not as virulent as A. phalloides, but like it in its POISONOUS effects. It differs from Amanitopsis in having a ring. Grows in woods and on wood-margins. Angora woods, West Philadelphia. On ground in mixed woods, open and grassy places in wood and wood-margins. August to September. _McIlvaine._ =A. recuti´ta= Fr.—having a fresh or new skin. =Pileus= convex then plane, _dry_, smooth, frequently bearing fragments of the volva, margin nearly even. =Stem= stuffed then hollow, attenuated, _silky_, volva circumscissile, becoming obliterated, margin closely pressed to stem; ring distant, white. =Gills= striate-decurrent. In pine woods. Common. No report upon quality. =A. Cæsa´rea= Scop.—king-like. (Called by the Greeks _Cibus Deorum_, food of the gods.) CAUTION. =Pileus= 3–8 in. across, hemispherical, then expanded, free from warts, distinctly striate on the margin, red or orange becoming yellow. =Gills= free, yellow. =Stem= 4–6 in. long, up to ¾ in. thick at base, slightly tapering upward, yellowish, flocculose, stuffed with white fibrils or hollow, with a conspicuous yellowish ring or veil. =Volva= white, large, distinct and membranous. =Spores= elliptical, 8–10µ _Peck_. Open woods, under pines on lawns. July to October. Reported from North Carolina, South Carolina, Massachusetts, Maryland, New Jersey, Ohio, Alabama, Louisiana, Pennsylvania, New York. _Peck_, Rep. 23, 32, 33, 48. This emperor of fungi is the most showy of its race. It grows to 10 in. in height. The cap reaches 8 in. in diameter and the stem over 1½ in. in thickness. In very much smaller specimens about the same proportions occur. The cap is at first ovate, then hemispherical, then expanded. It has no warts or scales upon it. The margin is distinctly striate. The flesh is white, yellow or reddish under the skin; next to the gills it is usually yellow.
