乌兹别克斯坦山区的一项微型真菌调查发现了几个葫芦科类群的标本。本文描述了南瓜属一新种，包括形态观察和分子系统学研究。对采集的南瓜属(Cucurbitaria)已知种的性别形态(子囊、子囊和子囊孢子)进行了比较，并进行了LSU、ITS、rpb2和tef1-α等多个基因座的系统发育分析。南瓜属(Cucurbitaria berberidicola sp.)11月在形态上与Cucurbitaria berberidis(属型)和C.oromedterranea密切相关。基于序列的分析证实了一个明显的区别，因此支持新物种的引入。
A survey of microfungi in the mountain areas of Uzbekistan revealed several specimens of cucurbitaria-like taxa. In this paper, one new species of Cucurbitaria is described based on a polyphasic approach, including morphological examination and molecular phylogeny. We compared the sexual morph (ascomata, asci, and ascospores) of the specimens collected with known species of Cucurbitaria and carried out multi loci (LSU, ITS, rpb2 and tef1-alpha) phylogenetic analyses. Cucurbitaria berberidicola sp. nov. is morphologically closely related to Cucurbitaria berberidis (the generic type) and C. oromediterranea. The sequence-based analyses verified a clear distinction, hence supporting the introduction of the new species.
