Morphological studies and phylogenetic analyses of DNA sequences from the internal transcribed spacer (ITS) regions of the nuclear ribosomal gene repeat, a partial sequence of RNA polymerase II subunit (rpb2), and a partial sequence of the large exon of tef1 (LEtef1) were used to investigate the taxonomy and systematics of nine Hypocrea species with anamorphs assignable to Trichoderma sect. Hypocreanum. Hypocrea corticioides and H. sulphurea are reevaluated. Their Trichoderma anamorphs are described and the phylogenetic positions of these species are determined. Hypocrea sulphurea and H. subcitrina are distinct species based on studies of the type specimens. Hypocrea egmontensis is a facultative synonym of the older name H. subcitrina. Hypocrea with anamorphs assignable to Trichoderma sect. Hypocreanum formed a well-supported clade. Five species with anamorphs morphologically similar to sect. Hypocreanum, H. avellanea, H. parmastoi, H. megalocitrina, H. alcalifuscescens, and H. pezizoides, are not located in this clade. Protocrea farinosa belongs to Hypocrea s.s.

九种 Hypocrea 的分类学和系统发育关系,具有可归属于 Trichoderma 部分 Hypocreanum 的无型态。

来自核核糖体基因重复序列的内部转录间隔区 (ITS) 区域的 DNA 序列、RNA 聚合酶 II 亚基 (rpb2) 的部分序列和 tef1 大外显子的部分序列 (LEtef1) 的形态学研究和系统发育分析是用于研究具有可归属于木霉属的无型态的九种 Hypocrea 物种的分类学和系统学。下垂。Hypocrea corticioides 和 H.sulfurea 被重新评估。描述了它们的无形木霉,并确定了这些物种的系统发育位置。根据对模式标本的研究,Hypocreasulfurea 和 H. subcitrina 是不同的物种。Hypocrea egmontensis 是旧名称 H. subcitrina 的兼性同义词。Hypocrea 具有可归属于木霉属的无定形。Hypocreanum 形成了一个良好支持的进化枝。五个物种的变形与 sect. 形态相似。Hypocreanum、H. avellanea、H. parmastoi、H. megalocitrina、H. alcalifuscescens 和 H. pezizoides 不在这个进化枝中。Protocrea farinosa 属于 Hypocrea ss
