We provide a taxonomic revision of the Rhizoscyphus ericae aggregate, an ecologically important species complex. We show that the prominent mycorrhizal fungus Rhizoscyphus ericae is conspecific with the bryophilous Hyaloscypha hepaticicola and, more generally, that the sexual Hyaloscypha and the asexual Meliniomyces are congeneric. This finding brings new perspectives to mycorrhizal research and sheds new light upon the taxonomy of the long-standing problematics of the Rhizoscyphus ericae aggregate. We describe a new species and report H. bicolor sporulating in vitro for the first time. The mycological and mycorrhizal sides of the same coin have never been formally associated, mainly because the sexual and asexual morphs of these fungi have been studied in isolation by different research communities. We stabilized the taxonomy of a widespread and ecologically well-studied group of root-associated fungi and link their various life-styles including saprobes, bryophilous fungi, root endophytes as well as fungi forming ericoid mycorrhizae and ectomycorrhizae.
