Leucoagaricus nympharum is a species of fungus in the family Agaricaceae.[1] [2]
Originally classified as Agaricus nympharum by the Hungarian mycologist Károly Kalchbrenner in 1873 and reclassified as Leucoagaricus nympharum by the French mycologist Marcel Bon in 1977.
Leucoagaricus nympharum is a large white dapperling mushroom with a distinctive scaly cap which resembles that of Chlorophyllum rhacodes only with a smaller, 4-10cm cap and a more starkly white colour. Despite its distinctive appearance it is seldom recorded and little known.[3]
