The Hypocrea schweinitzii complex and Trichoderma sect. Longibrachiatum

Hypocrea schweinitzii and related sexual and apparently strictly asexual Hy pocrea (Trichoderma) species form a monophyletic lineage known as the H. sc hweinitzii complex. The anamorphs correspond to Trichoderma sects. Longibra chiatum and Saturnisporum. The H. schweinitzii complex includes six holomor phic (Hypocrea + Trichoderma) and four anamorphic (Trichoderma) species. Th e following new species are proposed: Hypocrea andinensis, H. orientalis, H . novaeze-landiae, H. pseudokoningii and Trichoderma konilangbra. Trichoder ma parceramosum is found to be a later synonym of T. ghanense. The anamorph of H. pseudokoningii is T. pseudokoningii; the anamorph of H. schweinitzii is T. citrino-viride; the anamorph of H. jecorina is T. reesei. Hypocrea o rientalis and T. longibrachiatum are genetically very close to each other: differing in 1-5 bp in the ITS region of the rDNA gene; they differ from ea ch other in phenotypic characters. Trichoderma longibrachiatum is considere d to be a clonal derivative of H, orientalis or a similar Hypocrea species. No teleomorphs are known for the following species: T. ghanense, T. konila ngbra and T. saturnisporum. Keys to the species through their anamorphs and teleomorphs, and descriptions and illustrations are provided.
