Lepiota saponella is a species of agaric fungus in the family Agaricaceae.

[1] The fruit bodies (mushrooms) closely resemble those of the widespread species Lepiota cristata.

L. saponella can be distinguished by its soapy smell, dingy buff-coloured gills, and smaller scales on the cap surface.

Microscopically, its spores are more triangular than those of L. cristata.
