Amanita verna, commonly known as the fool's mushroom, destroying angel or the mushroom fool, is a deadly poisonous basidiomycete fungus, one of many in the genus Amanita. Occurring in Europe in spring, A. verna associates with various deciduous and coniferous trees. The large fruit bodies (i.e., the mushrooms) appear in summer and autumn; the caps, stipes and gills are all white in colour.
