puellaris Massee (1893) Lepiota rhacodes subsp.

Moser (1967) Leucoagaricus nympharum is a species of fungus in the family Agaricaceae.

[2][3] 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.

[2] 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.
