This study is based on the phylogenetic framework of ConocybesectionPilosellae and incorporates materials from Jilin Province. A systematic phylogenetic tree was constructed using maximum likelihood and Bayesian analyses of internal transcribed spacer region (ITS) and nuclear large subunit ribosomal DNA (nrLSU), and translation elongation factor 1-alpha () sequences. As a result, three new species were discovered in Jilin Province: , which emerges in broad-leaved forests during spring; , characterized by angular and submitriform or slightly hexagonal basidiospores; and , with basidiomata displaying a reddish hue when fresh and a bluish hue when dry. Additionally, a new record for China, was identified, characterized by the lack of distinct pubescence on the pileus and slightly hexagonal basidiospores, increasing the total number of species within sect. Pilosellae to 22. Key for sect. Pilosellae is provided, accompanied by morphological descriptions and line drawings for the new species and a new record for China.
本研究基于毛柄小皮伞组的系统发育框架,并纳入了来自吉林省的材料。利用内部转录间隔区(ITS)、核糖体DNA大亚基(nrLSU)和翻译延伸因子1-α()序列的最大似然法和贝叶斯分析构建了系统发育树。结果,在吉林省发现了3个新物种:春季出现在阔叶林中的 ;以角形和近方形或稍六边形的担孢子为特征的 ;新鲜时担子果呈红色、干燥时呈蓝色的 。此外,还鉴定出中国新记录种 ,其特征是菌盖无明显绒毛且担孢子稍呈六边形,使毛柄小皮伞组的物种总数增加到22种。提供了毛柄小皮伞组的检索表,并附有新物种和中国新记录种的形态描述及线条图。
