Species Description

Amanita muscaria is an iconic large mushroom, reaching cap sizes that range from 5-25cm in diameter, featuring a red or yellow cap with white warts (remaining veil tissue). These warts can appear yellow on younger specimens, but quickly become white. A skirt-like white ring is found on the upper part of the stalk, and at the base of the stalk are a stack of ruffled rings. The edge of the cap is striated and gills are detached, close, and a white to cream color. Amanita muscaria is classified as poisonous and has dangerous psychoactive effects.
