Extract from Wikipedia article: Amanita phalloides /æməˈnaɪtə fəˈlɔɪdiːz/, commonly known as the death cap, is a deadly poisonous basidiomycete fungus, one of many in the genus Amanita. Widely distributed across Europe, but now sprouting in other parts of the world, A. phalloides forms ectomycorrhizas 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 (mushrooms) appear in summer and autumn; the caps are generally greenish in colour with a white stipe and gills. Cap colour is variable, including white forms (see Taxonomy below), and thus not a reliable identifier.
