I was going with L. nuda over C. nuda based on IF, though I am not sure there is enough evidence to reliably assert one name over the other… I’ll leave it to the Clitocybe/Lepista pros to sort it out.

Though, I do have a bias preference for the name Clitocybe nuda over Lepista nuda for the same reason I wish Mutinus caninus was still Phallus caninus.
Eehehehe. ;)

Again, syn. Tricholoma lilaceum Quel., I agree. The question is which is the lates name in use.

No “lila” anythings under Lepista in IF, though under Clitocybe there are listings for C. lilaceoalba, C. lilacifolia, C. lilacina, and C. lilacinofusca (though they are not necessarily current species names).
I checked for Tricholoma nudum var. lilaceum, and it is a synonym for L. nuda.

Most of the European books list it as: Tricholoma nudum var. lilaceum

I can’t find this name in Index Fungorum or Google.

What are the macroscopic distinguishing characteristics between Lepista lilaceum and L. nuda? Or is the distinction geographic range??
