Leucocoprinus violaceus is a species of mushroom producing fungus in the family Agaricaceae.

When dry the cap and stem discolour brown whilst the gills turn slightly olive-brown.

Heinemann's study was based on specimens from Zaire, Central Africa (now the Democratic Republic of the Congo)[3] where they were found near Lake Edward and Lake Kivu in tufts on the ground of a plantation containing Grevillea plants.

[5] Whilst the edibility or potential toxicity of this species are unknown, Heinemann notes that the locals did not consume this mushroom.

[4] The specific epithet violaceus is Latin for violet[6] and refers to the purplish scales towards the base of this mushroom.
