Flammula is a dark brown-spored genus of mushrooms that cause a decay of trees, on whose bases they often fruit, forming clusters of yellowish brown mushrooms.

For nearly a century, Flammula was considered to be a synonym of Pholiota, a mushroom genus in the Strophariaceae.

Molecular analysis placed it outside of the Strophariaceae[1][2][3] and specifically in the Hymenogastraceae.

[4] As a distinct genus, the name Flammula is currently used.
