摘要

摘要结合形态特征和分子证据，提出了一个新的双锥虫属（双锥虫科，木聚亚目）——耿氏双锥虫。来自内蒙古一个倒下的被子植物分支的二锥虫，其特征是有3-14个包被在基质中，多孔的腹水和子囊孢子呈尿囊状，轻微弯曲，无菌和亚耶鲁状。根据ITS和β-微管蛋白序列的组合数据推断了锥虫科的系统发育。系统发育树表明，根和D.genheensis与另外两个多孔物种（D.betulaceicola和D.larissae）属于一个分支。在系统发育树中，耿河D.genheensis与Diatrype的其他采样物种明显分离。

Diatrype genheensis sp. nov. – a new wood-inhabiting species of Diatrypaceae (Xylariales, Ascomycota) from China

Abstract A new species of Diatrype (Diatrypaceae, Xylariales), D. genheensis, is proposed based on a combination of morphological features and molecular evidence. Diatrype genheensis, from a fallen angiosperm branch in Inner Mongolia, is characterized by having 3–14 perithecia embedded within a stroma, polysporous asci and ascospores that are allantoid, slightly curved, aseptate and subhyaline. The phylogeny of Diatrypaceae was inferred from a combined dataset of ITS and β-tubulin sequences. The phylogenetic tree indicated that D. genheensis belongs to a clade with two other polysporous species, D. betulaceicola and D. larissae. In the phylogenetic trees, D. genheensis was clearly separated from other sampled species of Diatrype.

期刊介绍： Canadian Journal of Plant Pathology is an international journal which publishes the results of scientific research and other information relevant to the discipline of plant pathology as review papers, research articles, notes and disease reports. Papers may be submitted in English or French and are subject to peer review. Research articles and notes include original research that contributes to the science of plant pathology or to the practice of plant pathology, including the diagnosis, estimation, prevention, and control of plant diseases. Notes are generally shorter in length and include more concise research results. Disease reports are brief, previously unpublished accounts of diseases occurring on a new host or geographic region. Review papers include mini-reviews, descriptions of emerging technologies, and full reviews on a topic of interest to readers, including symposium papers. These papers will be highlighted in each issue of the journal and require prior discussion with the Editor-in-Chief prior to submission.
