The authors confirm that Rhodocybe xylophila and Omphalina lilaceorosea are conspecific with Omphalia discorosea (Pil.), described from Siberia. They propose the new combination Omphalina discorosea (Pil.) Her. et Kotl., and report new localities from Bulgaria and France. A morphological and geographical overview of the species is included.
