 Joseph Ammirati and Howard Bigelow considered "Cortinarius heliotropicus", described by Charles Horton Peck 1914, to be the same species as "C. iodes" after examining the holotype specimens of both.According to the nomenclatural databases MycoBank and Index Fungorum, however, "Cortinarius iodes" does not have any synonyms.If they are indeed the same species, the name "C. iodes" has priority.
