Description

An entirely white, deadly amanita with a conical cap, white gills, a ring, and a sac-like volva.

Identification features

The cap may be irregularly conical and moist, and the stem often floccose. The whole base must be retained.

Identification checklist

The fruitbody is almost entirely white. The young cap is bell- to cone-shaped, gills are white and free, the ring is thin and fragile, and a large sack-like volva at the stem base may be hidden in soil.

White, 8–9 cm, initially almost globose, later conical to bell-shaped, silky-fibrillose and often umbonate.
Hymenophore

Stem
8–15 cm, white, often scaly, with a ragged ring and bulbous base enclosed in a sac-like volva.
Flesh
White and soft.

How to separate similar species

White Agaricus species have pink then brown gills and no sack-like volva. Spring destroying angel is also deadly and very similar. Always excavate and inspect the entire base.

Similar species

Interesting facts

Did you know? With white Amanita species the whole stem base must be exposed because the sac-like volva is an important feature of deadly species.
