The Hypocrea schweinitzii complex and Trichoderma sect. Longibrachiatum. 1998. (Studies in Mycology, 41). illus. 54 p. 4to. Paper bd.

Hypocrea schweinitzii and related sexual and apparently strictly asexual Hypocrea (Trichoderma) species form a monophyletic lineage known as the H. schweinitzii complex. The anamorphs correspond to Trichoderma sects. Longibrachiatum and Saturnisporum. The H. schweinitzii complex includes six holomorphic (Hypocrea + Trichoderma) and four anamorphic (Trichoderma) species. The following new species are proposed: Hypocrea andinensis, H. orientalis, H. novaezelandiae, H. pseudokoningii and Trichoderma konilangbra. Trichoderma 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. citrinoviride; the anamorph of H. jecorina is T. reesei. Hypocrea orientalis 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 each other in phenotypic characters. Trichoderma longibrachiatum is considered to be a clonal derivative of H. orientalis or a similar Hypocrea species. No teleomorphs are known for the following species: T. ghanense, T. konilanghra and T. saturnisporum. Keys to the species through their anamorphs and teleomorphs, and descriptions and illustrations are provided.
