'', or '' Hemipholiota''. Modern molecular evidence suggested recognition of a separate genus when sequences of a collection first identified as ''Pholiota oedipus'', now reclassified in ''Meottomyces'', revealed a unique branch. Subsequently, that species was studied by Holec and later as ''Phaeogalera oedipus'' was shown to be distinct from ''
