A new species, Hypocrea atroviridis, is described for the teleomorph of Trichoderma atroviride. Based on sequences of ITS-1, 5.8S, and ITS-2 regions of the rDNA complex and translation-elongation factor (EF-1α), T. atroviride and H. atroviridis form a well-supported clade within Trichoderma sect. Trichoderma. The conserved anamorphic phenotype of T. atroviride, observed for both conidial and ascospore derived cultures, was only found within that clade. In contrast, the teleomorph phenotype of H. atroviridis was morphologically indistinguishable from H. rufa, the teleomorph of T. viride. This Hypocrea phenotype may, therefore, be considered to be plesiomorphic within Trichoderma sect. Trichoderma, suggesting that genes controlling the expression of the teleomorph and anamorph evolve at different rates and that the genes controlling expression of the teleomorph are more conserved than are those controlling the expression of the anamorph.
一种新的物种，Hypocrea atroviridis，被描述为 Trichoderma atroviride 的有性型。基于核糖体 DNA 复合物的 ITS-1、5.8S 和 ITS-2 区域以及翻译延伸因子 (EF-1α) 的序列，T. atroviride 和 H. atroviridis 在 Trichoderma sect. Trichoderma 内形成了一个支持良好的分支。T. atroviride 的保守无性表型，无论是在分生孢子还是子囊孢子衍生的培养物中都观察到，仅存在于该分支中。相比之下，H. atroviridis 的有性型表型在形态上与 T. viride 的有性型 H. rufa 无法区分。因此，这种 Hypocrea 表型在 Trichoderma sect. Trichoderma 中可能被认为是原始的，这表明控制有性型和无性型表达的基因以不同的速度进化，并且控制有性型表达的基因比控制无性型表达的基因更保守。
