Descolea is a genus of fungi in the family Bolbitiaceae.

Described by mycologist Rolf Singer in 1952,[3] the widespread genus contains about 15 species.

[4] It was formerly placed in the family Cortinariaceae because of its limoniform basidiospores and its ectomycorrhizal lifestyle.

[5] A 2013 molecular phylogenetics study by Tóth et al. found it to be closely related to the genus Pholiotina[5] The genus Pseudodescolea, erected for the single Descolea-like species Pseudodescolea lepiotiformis, was formerly considered distinct until a 1990 study found it to be a synonym of Descolea antarctica.

[6] The genus name of Descolea is in honour of Horacio Raúl Descole (1910-1984), who was an Argentine apothecary, biochemist and botanist.
