To date 75 species of Hypocrea/Trichoderma forming teleomorphs are recognised in Europe. The 56 hyaline-spored species are here described in detail and illustrated in colour plates, including cultures and anamorphs. This number includes 16 new holomorphs, two new teleomorphs and nine anamorphs of species previously described as teleomorphs. Phylogenetic placement and relationships of the species are shown on the strict consensus tree, based on sequences of RNA polymerase II subunit b (rpb2) and translation elongation factor 1 alpha (tef1) exon, comprising 135 species of the genus Hypocrea/Trichoderma. All available holotypes of species described from Europe including some from North America have been examined. A dichotomous key to the species is provided primarily utilising ecological and morphological traits of the teleomorphs and, where necessary, morphology of the anamorphs and cultures, and growth rates. Species descriptions are subdivided among five chapters, arranged primarily according to the larger phylogenetic clades, viz. section Trichoderma with 13 species, the pachybasium core group with 13 species including four species with stipitate stromata (‘Podostroma’), species forming large effused stromata with 10 species including the section Hypocreanum, 9 species of the Brevicompactum, Lutea and Psychrophila clades, and 11 residual species of various smaller clades or of unknown phylogenetic placement. Finally, a list comprising dubious names and species excluded from Hypocrea that are relevant for Europe, or species claimed to occur in Europe by other authors is provided. Hypocrea minutispora is by far the most common species in Europe. For H. moravica, H. subalpina and H. tremelloides the anamorphs are newly described. The anamorphs of the latter two species and H. sambuci produce hyaline conidia on unusual structures new to Trichoderma. These three species form a new subclade of the morphologically strikingly different section Longibrachiatum, which is currently only represented by H. schweinitzii in Europe as a holomorph. The subclade is not named yet formally due to low statistical support. H. fungicola f. raduli is described as the new species H. austriaca, while H. hypomycella was found not to belong to Hypocrea. The typification of H. pilulifera, H. tremelloides and H. lutea has been clarified. Gliocladium deliquescens, the anamorph of H. lutea, is combined in Trichoderma. Species are epitypified where appropriate. Anamorph names are established prospectively to avoid numerous new combinations in future when they may be possibly used as holomorphic names if the ICBN is altered accordingly.

Hypocrea的欧洲物种第二部分：具有透明子囊孢子的物种。

迄今为止，欧洲已识别出75 种Hypocrea / Trichoderma形成的有形动物。此处详细描述了 56 种具有透明孢子的物种，并以彩图说明，包括培养物和无形体。这个数字包括 16 种新的全形动物、两种新的有目的动物和 9 种以前被描述为有目的动物的无形动物。基于 RNA 聚合酶 II 亚基 b ( rpb2 ) 和翻译延伸因子 1 α ( tef1 ) 外显子的序列，物种的系统发育位置和关系显示在严格的共有树上，包括 135 种Hypocrea /木霉属. 已经检查了从欧洲描述的所有可用物种的正型模型，包括一些来自北美的物种。主要利用有形动物的生态和形态特征，必要时，无性动物和培养物的形态和生长速率提供了该物种的二分法关键。物种描述分为五个章节，主要根据较大的系统发育进化枝排列，即。木霉科13 种，厚皮纲核心群 13 种，其中有具柄基质的 4 种（' Podostroma '），形成大型渗出基质的物种有 10 种，包括Hypocreanum部分，Brevicompactum、Lutea和Psychrophila进化枝和各种较小进化枝或未知系统发育位置的 11 种残留物种。最后，提供了一份清单，其中包含与欧洲相关的可疑名称和被排除在Hypocrea之外的物种，或其他作者声称在欧洲出现的物种。Hypocrea minutispora是迄今为止欧洲最常见的物种。对于H. moravica、H. subalpina和H. tremelloides无形体是新描述的。后两个物种和H. sambuci的无形体在木霉属新发现的不寻常结构上产生透明的分生孢子。这三个物种形成了形态截然不同的部分的新亚群Longibrachiatum，目前在欧洲仅由H. schweinitzii代表为全形体。由于统计支持不足，该子分支尚未正式命名。H. 真菌f. raduli被描述为新物种H. austriaca，而H. hypomycella被发现不属于Hypocrea。H. pilulifera、H. tremelloides和H. lutea的分类已经明确。Gliocladium deliquescens是H. lutea的无形体，在木霉中结合. 适当时对物种进行表型化。Anamorph 名称是前瞻性建立的，以避免将来在 ICBN 相应更改时它们可能用作全纯名称时出现大量新组合。
