The new stipitate species of Hypocrea, H. seppoi; is described, based on material freshly collected in Finland. Characterization of this species includes morphology of teleomorph and anamorph, culture studies and molecular phylogeny. H. seppoi is compared to the other European soil-inhabiting, stipitate Hypocrea species. It is characterized by small stromata, thin fibrous stipe, perithecia decurrent on the stipe, and by conidia that are smaller than those of H. leucopus and H. nybergiana. In addition, this work confirms the congenerity of Podostroma and Podocrea with Hypocrea on molecular phylogenetic grounds using sequences of the nuclear genes coding for RNA polymerase II subunit b (rpb2), translation elongation factor 1 alpha (tef1), and endochitinase (chi15-8).
基于在芬兰新采集的材料，描述了肉座菌属的新柄生种——塞波肉座菌（Hypocrea seppoi）。该物种的特征包括有性型和无性型的形态、培养研究以及分子系统发育。将塞波肉座菌与其他欧洲土壤栖息的柄生肉座菌物种进行了比较。其特征为子座小、菌柄纤细呈纤维状、子囊壳沿菌柄下延，且分生孢子比白肉座菌（Hypocrea leucopus）和尼氏肉座菌（Hypocrea nybergiana）的分生孢子小。此外，本研究利用编码RNA聚合酶II亚基b（rpb2）、翻译延伸因子1α（tef1）和内切几丁质酶（chi15 - 8）的核基因序列，从分子系统发育角度证实了柱孢肉座菌属（Podostroma）和柄孢肉座菌属（Podocrea）与肉座菌属的同宗关系。
