Hypocrea voglmayrii sp. nov. from the Austrian Alps represents a new phylogenetic clade in Hypocrea/Trichoderma.
The holomorph of the new species Hypocrea voglmayrii (Hypocreales, Ascomycota, Fungi) is described by a combined approach, using morphology of the teleomorph, morphology of the anamorph, culture studies and phylogenetic analyses of ITS1 and 2, ech42 and rpb2 gene sequences. Its anamorph Trichoderma voglmayrii is described as a new anamorph species. Unlike most other species of Hypocrea the teleomorph of H. voglmayrii occurs on dry standing trunks and exhibits well defined black ostioles. Although exclusively collected at higher altitudes, this species grows at 35 C in culture. Hypocrea voglmayrii develops pale yellowish to greenish conidia, a yellowish pigment and a coconut-like odor on CMD. Phylogenetically, H. voglmayrii forms a distinct, isolated branch between the section Trichoderma and the H. pachybasioides clade but does not associate with any of these clades in different gene trees.
