Amanita phalloides   (Death Cap Amanita)
North America, Europe
Cap 6-12 cm diameter, stem 7-12 cm tall * 1 - 1.5 cm thick
Lethally poisonous

This is a lethally poisonous, medium to large, fleshy agaric with greenish olive cap, whitish stem, ring, no patches but distinctive volval sheath. As the volva, which may be hidden by leaf litter, is a distinctive and diagnostic feature, it is important to remove some debris to check for it.

Cap at first round to egg-shaped and then flat. Varies greatly in colour from gray-white to green and yellow brown and has dark radial lines from the center. Sometimes with lots of veil remnants. Gills free, close, white, can turn yellow. Stem white with a scattering of grayish-olive scales and with a swollen, ragged, sac-like white volva (base). Ring white or colored like the stem, broad, thin, persistent.

Similar species Some Volvariella species look similar to older speciemens of Amanita phalloides. They are distinguished by a pale pink spore deposit and lack of a stem ring.
