Abstract

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.

摘要

采用核核糖体基因重复内部转录间隔区（ITS）区域的 DNA 序列、RNA 聚合酶 II 亚基（rpb2）的部分序列和 tef1 大亚外显子（LEtef1）的部分序列进行形态学研究和系统发育分析，以调查具有 assignable Trichoderma sect. Hypocreanum 无性型的九个 Hypocrea 种的分类学和系统发育。重新评估 Hypocrea corticioides 和 H. sulphurea。描述了它们的 Trichoderma 无性型，并确定了这些物种的系统发育位置。Hypocrea sulphurea 和 H. subcitrina 是根据对模式标本的研究确定的不同物种。Hypocrea egmontensis 是较旧名称 H. subcitrina 的兼性同义词。具有可归为 Trichoderma sect. Hypocreanum 的无性型的 Hypocrea 形成了一个支持良好的分支。五个具有与 sect. Hypocreanum 形态相似的无性型的物种，Hypocrea avellanea、H. parmastoi、H. megalocitrina、H. alcalifuscescens 和 H. pezizoides，不在这个分支中。Protocrea farinosa 属于 Hypocrea s.s.
