Leucoagaricus leucothites

Leucoagaricus leucothites, the white dapperling, or white Agaricus mushroom, is a species of agaric fungus. The species was originally described as Agaricus leucothites by Carlo Vittadini in 1835, and bears similarity to species of that genus.[2] Solomon Wasser transferred it to Leucoagaricus in 1977.[3] While sometimes regarded as edible,[4] the species is suspected of being poisonous due to gastric-upset-causing toxins.[5] It could also be confused with the deadly Amanita ocreata.[4]
