Leucocoprinus fragilissimus, commonly known as the fragile dapperling,[3] is a species of gilled mushroom in the family Agaricaceae.


The species was first documented by French mycologist Narcisse Théophile Patouillard in 1900.[4]


The cap of the fruit body is up to 4.5 cm (1.8 in) wide, bell-shaped when young and growing to convex in maturity. It has a pale yellow colour that fades with age, and white gills. The narrow stalk is between 1 and 3 mm thick and very fragile.[5]

Similar species[edit]

Leucocoprinus magnicystidiosus is a similar mushroom, with a darker disc and larger cheilocystidia.[5]

Habitat and distribution[edit]

Like all Leucocoprinus species, L. fragilissimus is a saprotroph, living on very decayed plant matter (humus or compost). It grows solitarily or sparsely in wooded areas.[6] The species is found in southern North America, South America, southern Europe, Africa, southern and eastern Asia, Australia, and New Zealand.[3]

Toxicity and chemistry[edit]

The toxicity of this mushroom is unknown.[5]
