ABSTRACT: Mycena viscidocruenta is presently known only from the Antipodes. Collections from far eastern Russia were shown to be closely related both by morphology and by sequence homology. Phylogenetic analyses based on ribosomal LSU and ITS sequences show that the M. viscidocruenta clade is sister to Panellus stypticus and Panellus (Dictyopanus) pusillus, two laterally stipitate taxa, in the panelloid clade. Resinomycena rhododendri, the type species of Resinomycena is basal to this group. A new genus, Cruentomycena, is proposed to accommodate C. viscidocruenta (typus generis) and a new species, C. kedrovayae.
