Abstract

Cortinarius species are widely distributed in the world and constitute a diverse group of ectomycorrhizal fungi that are associated with a broad range of plant hosts. The species diversity of this genus has been investigated in China, but it remains poorly understood, especially in the subtropical region. In this study, one new section, six novel species, one new combination, one new name, and one new record of Cortinarius are reported from subtropical China based on the morphological and molecular evidences. Cortinarius lilacinicarpus, C. sinocalaisopus, C. sinosalor, C. vividus spp. nov., C. orientisalor nom. nov., and C. illibatus are typical species of the section Delibuti. Cortinarius macroflavicapus sp. nov. belongs to Macroflavicapi sect. nov., a new section in the subgenus Dermocybe. Cortinarius tianbaoyanensis sp. nov. and C. dryadicola comb. nov. belong to the section Spilomei. Detailed descriptions, basidiocarps, and microscopic photographs are provided for these species. In addition, C. leptospermorum comb. nov. in the section Pauperae and subgenus Dermocybe is proposed.

标题中国亚热带新分类群——褐藻的新认识。

天竺葵属真菌在世界上分布广泛，是一种与多种植物寄主有关的外生菌根真菌。该属植物的种类多样性已在中国进行了调查，但对其了解甚少，特别是在亚热带地区。根据形态学和分子生物学证据，在中国亚热带地区报道了一新科、六新种、一新组合、一新名和一新记录。淡紫色金丝桃、中国金丝桃、中国金丝桃、鲜木金丝桃、东方金丝桃和中国金丝桃是金丝桃科的典型种。大黄皮虫属大黄皮虫亚属新分支。天宝雁海棠和黄翅海棠。11月属于斯皮尔梅节。提供了这些物种的详细描述、担子果和显微照片。此外，细尾草梳。11 .在鸭鳃亚属中提出了鸭鳃亚属。
