Lepiota subincarnata  Lepiota subincarnata is a gilled mushroom of the genus "Lepiota" in the order Agaricales. It is known to contain amatoxins and consuming this fungus can be potentially lethal. First described scientifically by the Danish mycologist Jakob Emanuel Lange in 1940, the species is found in Asia, Europe, and North America. Bon and Boiffard described "Lepiota josserandii" in 1974, which turned out to be the same species.
