Russula subsection Amoeninae is morphologically defined by a dry velvety pileus surface, a complete absence of cystidia with heteromorphous contents in all tissues, and spores without amyloid suprahilar spot. Thirty-four species within subsection Amoeninae have been published worldwide. Although most Russula species in South Korea have been assigned European or North American names, recent molecular studies have shown that Russula species from different continents are not conspecific. Therefore, the present study aims to: 1) define which species of Russula subsection Amoeninae occur on each continent using molecular phylogenetic analyses; 2) revise the taxonomy of Korean Amoeninae. The phylogenetic analyses using the internal transcribed spacer (ITS) and multilocus sequences showed that subsection Amoeninae is monophyletic within subgenus Heterophyllidiae section Heterophyllae. A total of 21 Russula subsection Amoeninae species were confirmed from Asia, Australia, Europe, North America, and Central America, and species from different continents formed separate clades. Three species were recognized from South Korea and were clearly separated from the European and North American species. These species are R. bella, also reported from Japan, a new species described herein, Russula orientipurpurea, and a new species undescribed due to insufficient material.

来自韩国的红菇小节的分类学修订

芸苔小节Amoeninae在形态上定义为干燥的天鹅绒般的绒毛表面，在所有组织中完全不存在具有异质含量的孢子虫，以及没有淀粉样上皮斑的孢子。在世界范围内，Amoeninae子节中的34种已被发表。尽管韩国的大多数红菇物种已被赋予欧洲或北美名称，但最近的分子研究表明，来自不同大陆的红菇物种并不是同种的。因此，本研究的目的是：1）通过分子系统发育分析，确定每个大陆上存在哪一种红菇亚种。2）修改韩国Amoeninae的分类法。使用内部转录间隔区（ITS）和多基因座序列的系统发育分析表明，Amoeninae子在杂种亚科异种亚科内是单系的。来自亚洲，澳大利亚，欧洲，北美和中美洲的总共21种红菇亚种被确认，不同大陆的物种形成了不同的进化枝。从韩国认识到了三种，并与欧洲和北美的物种明显分开。这些物种是日本也报道过的R. bella，本文所述的新物种Russula Orientipurpurea和由于材料不足而未描述的新物种。来自不同大陆的物种形成了不同的进化枝。从韩国认识到了三种，并与欧洲和北美的物种明显分开。这些物种是日本也报道过的R. bella，本文所述的新物种Russula Orientipurpurea和由于材料不足而未描述的新物种。来自不同大陆的物种形成了不同的进化枝。从韩国认识到了三种，并与欧洲和北美的物种明显分开。这些物种是日本也报道过的R. bella，本文所述的新物种Russula Orientipurpurea和由于材料不足而未描述的新物种。
