The first large-scale survey of sexual and asexual Trichoderma morphs collected from plant and fungal materials conducted in Southern Europe and Macaronesia including a few collections from French islands east of Africa yielded more than 650 specimens identified to the species level. Routine sequencing of tef1 revealed a genetic variation among these isolates that exceeds previous experience and ca. 90 species were recognized, of which 74 are named and 17 species newly described. Aphysiostroma stercorarium is combined in Trichoderma. For the first time a sexual morph is described for T. hamatum. The hitherto most complete phylogenetic tree is presented for the entire genus Trichoderma, based on rpb2 sequences. For the first time also a genus-wide phylogenetic tree based on acl1 sequences is shown. Detailed phylogenetic analyses using tef1 sequences are presented in four separate trees representing major clades of Trichoderma. Discussions involve species composition of clades and ecological and biogeographic considerations including distribution of species.

在南欧和马卡罗尼西亚对植物和真菌材料中收集的有性和无性木霉的形态进行了首次大规模调查，其中包括从非洲东部法国岛上收集的一些样本，得到了鉴定到物种水平的650多个标本。常规测序TEF1透露这些菌株超过以往的经验和之间的遗传变异CA。确认了90种，其中74种被命名，新描述了17种。在木霉属中合并无形螨属的stercorarium 。首次报道了T. hamatum的性形态。为整个属提出了迄今为止最完整的系统发育树木霉属，基于rpb2序列。首次也显示了基于acl1序列的全属系统发育树。使用tef1序列进行的详细的系统发育分析呈现在代表木霉主要进化枝的四个不同的树中。讨论涉及进化枝的物种组成以及生态和生物地理因素，包括物种分布。
