Holomorph of Trichoderma tongrenense sp. nov. (Hypocreales, Ascomycota) with green ascospores from China

The holomorph of Trichoderma tongrenense sp. nov. with green ascospores is described from Guizhou, China. Phylogenetic analyses based on sequences of the translation elongation factor 1 alpha (tef1) and RNA polymerase II second largest subunit (rpb2) genes indicated its position within the Harzianum lineage of Trichoderma (Hypocrea), together with its internal transcribed spacer RNA (ITS) sequence and morphology, suggest that it is a new species.
