摘要

基于形态学和系统发育证据，本文描述了 Delibuti 科 Cortinarius 属的三个新种，即 C. fibrillososalor、C. pseudosalor 和 C. subtropicus。Cortinarius pseudosalor 在形态上与 C. salor 极为相似，但与后者的区别在于后者的基部孢子较小，呈粗疣状。Cortinarius fibrillososalor 的纤维状绒毛很容易区分。与 Delibuti 部分的其他成员相比，C. subtropicus 的绒毛在成熟时变成棕色，没有淡紫色。系统进化分析使用了 ITS 和 LSU 序列的组合数据集。Delibuti节的系统发育重建结果显示，这三个新种分别聚类并形成了完全支持的独立世系。本研究提供了 Delibuti 节三个新种及相关种的检索表。

Three new species of Cortinarius section Delibuti (Cortinariaceae, Agaricales) from China

Three new species of Cortinarius section Delibuti, namely C. fibrillososalor, C. pseudosalor, and C. subtropicus are described as new to science based on morphological and phylogenetic evidences. Cortinarius pseudosalor is extremely morphologically similar to C. salor, but it differs from the latter by smaller coarsely verrucose basidiospores. Cortinarius fibrillososalor can be easily differentiated by its fibrillose pileus. The pileus of C. subtropicus becomes brown without lilac tint at maturity comparing with other members of section Delibuti. A combined dataset of ITS and LSU sequences was used for phylogenetic analysis. The phylogenetic reconstruction of section Delibuti revealed that these three new species clustered and formed independent lineages with full support respectively. A key to the three new species and related species of section Delibuti is provided in this work.
