Three European species of Hypocreawith reddish brown stromata and green ascospores

The European species Hypocrea epimyces(Hypocreales, Ascomycota, Fungi) is redescribed based on the holotype including the drawing on its envelope by Saccardo and freshly collected material. The holomorphs of two closely related species, H. alniand H. brunneoviridis, are described as new species of the genus. They are characterized with morphological and molecular methods, including culture studies and phylogenetic analyses with internal transcribed spacers 1 and 2 as a part of the ribosomal RNA gene cluster, calmodulin, endochitinase, intron 4 of the translation elongation factor 1-alpha gene, and a part of the RNA polymerase II subunit B gene as phylogenetic markers. All species described here have green ascospores. Although phylogenetically closely related to H. lixii, they form reddish brown instead of green to black stromata. Except for H. brunneoviridis, forming nearly gliocladium-like conidiophores, the anamorphs of these species are similar to each other but vary in the angles of conidiophore branches and phialides, in phenotypic arrangement of conidiation on growth plates and in growth rates of cultures.
