It was originally described as a subgenus of Mycena by the mycologist Rolf Singer before he moved to its own genus two years later.

[1] It was formerly thought to belong in the family Tricholomataceae, but a molecular phylogenetics study found it to be more closely The genus Cyptotrama in the Physalacriaceae.

[2] Rolf Singer had previously hypothesized these two genera to be closely related based on morphological features in 1986.

[2] It contains five species that are widely distributed in tropical areas.
