Abstract A new species, Cyptotrama fagiphila, sp. nov., and a noteworthy species recently described from China, Cibaomyces glutinis, are reported from Europe. Their systematic position was confirmed by DNA sequence analyses of the ITS and partial 28S regions of the nuclear rDNA cistron. Based on these data, an emendation of Rhizomarasmius is also proposed to encompass the alpine species Oudemansiella oreina and the marasmioid species Marasmius setosus, and the appropriate combinations Rhizomarasmius oreinus comb. nov. and R. setosus comb. nov. are introduced. The position of Laccariopsis (Oudemansiella) mediterranea is also discussed. Unpublished data on the holotypes of the extra-European species Cyptotrama hygrocyboides, C. platensis, and C. songolarum are provided along with sequence data that
