| Based on type studies and freshly collected material we here re-instate the genus Thyronectria (Nectriaceae, Hypocreales). Species of this genus were recently for the most part classified in the genera Pleonectria (Nectriaceae) or Mattirolia (Thyridiaceae), because Thyronectria and other genera had been identified as members of the Thyridiaceae due to the presence of paraphyses. Molecular phylogenies based on several markers (act, ITS, LSU rDNA, rpb1, rpb2, tef1, tub) revealed that the Nectriaceae contain members whose ascomata are characterised by long, more or less persistent, apical paraphyses. All of these belong to a single genus, Thyronectria, which thus has representatives with hyaline, rosy, green or even dark brown and sometimes distoseptate... |

| The circumscription of the genus Acremonium (Hypocreales) was recently reviewed on the basis of a DNA phylogenetic study. Several species were subsequently transferred to Sarocladium, but the relationships between both genera remained unresolved. Based on multilocus phylogenetic inferences combined with phenotypic data, we have revised the species concepts within Sarocladium and some genetically related species of Acremonium. As a result of these studies, six species are described as new, viz. S. bifurcatum, S. gamsii, S. hominis, S. pseudostrictum, S. subulatum and S. summerbellii. In addition, the new combinations S. implicatum and S. terricola are proposed for A. implicatum and A. terricola, respectively. Sarocladium attenuatum is confirmed as synonym... |

| 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... |
