摘要

皮菌科属于皮菌纲，皮菌纲，共有14属。本研究通过形态学观察和多位点系统发育分析，将Pseudoxenochalara gen. nov引入皮科新属。分析了微管蛋白(BenA)、核糖体聚合酶II第二大亚基(RPB2)、28S rDNA (LSU)和内部转录间隔段rDNA区域(ITS1-5.8S-ITS2)的部分序列。该属包括一个新种，P. grumantiana，从巴伦支堡(斯瓦尔巴群岛)定居点附近的北极苔原土壤中分离出来。描述了绿豆豆的无性形态。序列数据以及宏观和微观形态特征将P. grumantiana与所有已知的皮科物种区分开来。

Pseudoxenochalara gen. nov. (Dermateaceae, Helotiales), with P. grumantiana sp. nov. from the Svalbard archipelago

The family Dermateaceae belongs to the Helotiales order, the class Leotiomycetes, and consists of 14 genera. In this study, we introduce the new genus Pseudoxenochalara gen. nov. to the Dermateaceae family, which is supported by morphological observations and multilocus phylogenetic analysis. Partial sequences of the loci encoding ?-tubulin (BenA), ribosomal polymerase II second largest subunit (RPB2), 28S rDNA (LSU) and internal transcribed spacer rDNA region (ITS1-5.8S-ITS2) were analysed. This genus comprises one new species, P. grumantiana, isolated from the soil of the Arctic tundra near the settlement of Barentsburg (the Svalbard archipelago). The asexual morph of P. grumantiana was described. The sequences data, as well as the macroand micromorphological characteristics distinguish P. grumantiana from all known species in the Dermateaceae family.
