[****] Volva rudimentary, flocculose, wholly disappearing.
A. viro´sa Fr.—virus, poison.
Shining white. Pileus 3–4 in. broad, fleshy, at first conical and acute, afterwards bell-shaped, then expanded, naked, viscous in wet weather, shining when dry, margin always even, but most frequently unequal, turned backward and inflexed. Flesh white, unchangeable. Stem 4–6 in. long, wholly stuffed, almost solid, split up into longitudinal fibrils, cylindrical from the bulbous base, often compressed at the apex, torn into scales on the surface, springing from a lax, wide, thick volva, which bursts open at the apex. Ring close to the top, lax, silky, splitting up into floccose fragments. Gills free, thin, narrow, narrowing at both ends, but a little broader in front, not decurrent on the stem (although the apex of the stem is often striate), crowded, somewhat floccose at the edge. Fries.
The pilei are most frequently oblique, extended and lobed on one side as in Hygrophorous conicus, scarcely ever depressed. The pileus rarely becomes yellow. The fragments of the veil often adhere to the edge of the gills.
