Solitary in woods. Port Jefferson, Suffolk county. July.
The species resembles Amanita verna, from which it is separated by its large persistent annulus, the elongated downwardly tapering bulb of its stem, and especially by its elliptical spores. Peck, 50th Rep. N.Y. State Bot.
I have not seen this species. Its resemblance to A. verna is enough to place the ban upon it until it has been tested.
A. map´pa Fr.—mappa, a napkin. From the volva. Pileus 2–3 in. broad, commonly white or becoming yellow, slightly fleshy, convexo-plane, obtuse or depressed, orbicular, dry, margin for the most part even. Stem 2–3 in. long, 3–5 lines thick, stuffed then hollow, almost equal above the bulb, rather smooth, white. Ring superior, soft, lax, here and there torn. Volva regularly circularly split, somewhat obliterated; the globoso-bulbous base united with the stem, with an acute and distant margin; the portion covering the pileus divided into broad, irregular, somewhat separating scales. Gills annexed, crowded, narrow, shining, white. Fries.
Odor stinking. The color is that of A. phalloides, with which A. virosa exactly agrees, more rarely straw color, lemon-yellow, becoming green.
In mixed woods. Frequent. Stevenson.
Spores spheroid, 7–10µ K.; 8–9×6–8µ B.; subglobose, 7–9µ diameter Massee.
New York woods and fields, common, September to October, Peck, 22d Rep.; North Carolina, Curtis; New England, Frost; Minnesota, Johnson; Ohio, Morgan; District Columbia, Miss Taylor.
POISONOUS.
Probably but a variety of A. phalloides.
