death cap

Amanita phalloides, commonly known as the death cap, is a poisonous basidiomycete fungus, one of many in the genus Amanita. Widely distributed across Europe, A. phalloides associates with various deciduous and coniferous trees. In some cases, death cap has been accidentally introduced to new regions with the cultivation of non-native species of oak, chestnut, and pine. The large fruiting bodies (i.e., the mushrooms) appear in summer and autumn; the caps are generally greenish in colour, with a white stipe and gills.
