Contribution to the nomenclature of Cortinarius subgenus Dermocybe

The correct citation of Dermocybe as a subgenus of Cortinarius should be: Cortinarius (Fr.) Fr. subgen. Dermocybe (Fr.) Sam., since it was Saccardo who definitely treated Dermocybe at the subgeneric level under the genus Coriinarius . According to the rules of nomenclature, the type species of Dermocybe must be Coriinarius cinnamomeus (L.: Fr.) Fr. Cortinarius croceus (Schaeff.: Fr.) H˜jiland is invalidly combined, and the new combination Cortinarius croceus (Schaeff.) Heiland is proposed. A neotype for Cortinarius croceus is also proposed. Hydrocybe palustris Moser is invalidly published since the author simultaneously published an alternative name, Cortinarius palusiris Moser. Therefore the combinations Dermocybe palustris (Moser) Moser and Coriinarius palusiris (Moser) Nez‐dojminogo are invalid. The earliest legitimate name of the taxon is Cortinarius huronensis Ammirati & Smith. Cortinarius sphagneti Orton is a later homonym of Cortinarius shagneti Sing. The earliest legitimate name of the former taxon is Cortinarius tubarius Ammirati & Smith.
