Comment:Hymenogaster purpureus J.W.Cribb not used as the basionym for a combination in Cortinarius due to the existence of Cortinarius purpureus (Bull.) Bidaud, Moënne-Locc. & Reumaux (1994).
Comment:Basionym given as "Protoglossum purpureum (J.W. Cribb) T.W. May" instead of Hymneogaster purpureus J.W.Cribb but new name is valid because full details of the basionym are provided.
