[1][2] In 1981 Jörg H. Raithelhuber identified as separate a subgroup having very crowded strongly decurrent gills and spores which are oval in section to almost spherical, including Lepista flaccida and Lepista gilva.

[1][2] Then in 2012 Alfredo Vizzini and Enrico Ercole published a paper which confirmed by DNA sequencing analysis that these mushrooms are a separate clade from other parts of Lepista and Clitocybe.

The paper includes a detailed phylogram covering relevant species.

[2] The new genus is recognized by Species Fungorum,[4] and the Global Biodiversity Information Facility.

"Basionym year" means the date of the original description of the species under its present specific name, whichever genus it belonged to at the time.
