Species of Gnomoniopsis are leaf- and stem-inhabiting pyrenomycetes that infect plants in Fagaceae, Onagraceae and Rosaceae. Morphology and analyses of DNA sequences from three ribosomal DNA and protein coding regions, namely β-tubulin, translation elongation factor 1α (tef-1α) and the ITS region including ITS1, 5.8S rDNA and ITS2, were used to define species in Gnomoniopsis. Secondary structural alignment of the ITS region across four genera in Gnomoniaceae was used to increase the potential number of homologous positions in the ITS alignment. Ascospore isolates were grown from newly collected specimens. Type specimens were compared with these specimens to determine their identity. In this paper a recent concept of Gnomoniopsis is confirmed with phylogenetic resolution of additional species. Four new combinations and one new species are proposed. Nine species are described and illustrated, and a key is provided to the 13 species currently recognized in Gnomoniopsis.
格姆尼奥皮斯属物种是叶栖和茎栖的外囊菌，感染壳斗科、柳叶菜科和蔷薇科的植物。形态学和三个核糖体 DNA 及蛋白质编码区（β-微管蛋白、翻译延伸因子 1α（tef-1α）和包括 ITS1、5.8S rDNA 和 ITS2 的 ITS 区）的 DNA 序列分析用于定义格姆尼奥皮斯属中的物种。在格姆尼奥皮斯科的四个属中对 ITS 区的二级结构比对，增加了 ITS 比对中同源位置的潜在数量。从新采集的标本中分离出子囊孢子。将模式标本与这些标本进行比较以确定其身份。本文通过附加物种的系统发育分辨率，确认了格姆尼奥皮斯属的最新概念。提出了四个新的组合和一个新种。描述和说明了 9 个种，并提供了 13 种目前在格姆尼奥皮斯属中公认的种的关键特征。
