    Samenvatting

    The rare apothecial, cupulate fungus Geopora pellita (Pyronemataceae) is characterized by a uniquely bright yellow-orange excipulum. We here re-examine its affiliations by use of morphological, molecular phylogenetic and ultrastructural analyses. G. pellita appears as phylogenetically rather isolated, being the sister group of a clade comprising Phaeangium, Picoa, the majority of the Tricharina species, and the remaining Geopora species. Based on its phylogenetic position and its unique combination of morphological characters, we assign G. pellita to Hoffmannoscypha, gen. nov., as H. pellita, comb. nov. As in a previous study, analyses of both large subunit (LSU) and internal transcribed spacer (ITS) ribosomal DNA suggest that the remaining genus Geopora is paraphyletic, with the hypogeous, ptychothecial type species more closely related to Picoa and Phaeangium than to the greyish-brownish cupulate and apothecial Geopora spp., indicating that the latter should be reassigned to the genus Sepultaria. The current study also shows that ITS confirm LSU data regarding the polyphyly of Tricharina. © 2012 German Mycological Society and Springer-Verlag Berlin Heidelberg.
