There might be two names for this fungus. It seems to be a perfect fit for the keys and the descriptions by both Bigelow and Gregory. Redhead dismisses all species in Bigelow, but fails to state why this one does not match. When I asked Denise Gregory about this species she wrote “Hi Darvin, I don’t believe that Clitocybe scabriuscula is truly a Clitocybe, even though I have it listed in my monograph.” After doing a literature search it seems that Clitocybe scabriuscula has NOT been moved to Omphalina, Contumyces or anything else. It currently remains Clitocybe scabriuscula on both Zip Code Zoo and Index Fungorum and does NOT appear in any Omphalina key, including the lengthy keys in Moser (33 species) or Hanson (27 species). Bigelow keys out at least 45 species of omphalinoid Clitocybes in his book but does NOT include Omphalina rosella.
On the other hand, the two color photos in Antonin and in Dahncke are an excellent fit. The description in Redhead, supported by the opinion of Dr. Desjardin, strongly supports Contumyces rosellus var. vinacea.
