| Stromata of Trichoderma species having green ascospores were collected in various regions of China. Based on morphology of the sexual and asexual morph, culture characteristics, and sequence analyses of rpb2 and tef1 genes, 17 species with green ascospores were identified. Among them, Trichoderma rosulatum, T. rufobrunneum and T. stipitatum are described as new species, and seven other species are reported for the first time from China. Trichoderma rosulatum produces small bright yellow or pale greenish stromata with dense dark green ostioles and gliocladium-like conidiophores, shows a close relationship to T. thelephoricola, and belongs to the Chlorospora clade. Trichoderma rufobrunneum, which typically forms reddish brown stromata, is recognised as a... |
