Amanita phalloides ( AM-ə-NY-tə fə-LOY-deez), commonly known as the death cap, is a deadly poisonous basidiomycete fungus and mushroom, one of many in the genus Amanita. Originating in Europe but later introduced to other parts of the world since the late twentieth century, A. phalloides forms ectomycorrhizae with various broadleaved trees. In some cases, the death cap has been introduced to new regions with the cultivation of non-native species of oak, chestnut, and pine. The large fruiting bodies appear in summer and autumn; the caps are generally greenish in colour with a white stipe and gills. The cap colour is variable, including white forms, and is thus not a reliable identifier.
