Lethal amanitas (Amanita sect. Phalloideae) cause many casualties worldwide. Recent molecular phylogenetic studies revealed diverse lethal Amanita spp. in China. Here a 5-gene phylogeny (nuc rDNA region encompassing the internal transcribed spacers 1 and 2 with the 5.8S rDNA, the D1-D3 domains of nuc 28S rDNA, and partial RNA polymerase II second largest subunit, translation elongation factor 1-α and β-tubulin genes) is used to investigate the phylogenetic lineages and species delimitation in this section. Thirteen species are recognized, including four new species, namely A. griseorosea, A. molliuscula, A. parviexitialis, and A. subfuliginea They are documented with morphological, multigene phylogenetic, and ecological evidence, line drawings, and photographs and compared with similar species. A key to the Chinese lethal Amanita species is provided.
剧毒鹅膏菌（鹅膏菌属毒伞亚属）在全球范围内造成了许多人员伤亡。最近的分子系统发育研究揭示了中国境内多种剧毒鹅膏菌物种。在此，利用一个包含5个基因的系统发育树（核糖体DNA区域，包括内部转录间隔区1和2以及5.8S核糖体DNA、核糖体28S DNA的D1 - D3结构域，以及部分RNA聚合酶II第二大亚基、翻译延伸因子1 - α和β - 微管蛋白基因）来研究该亚属的系统发育谱系和物种界定。共识别出13个物种，包括4个新物种，即灰玫瑰色鹅膏菌、软质鹅膏菌、小致死鹅膏菌和近烟色鹅膏菌。文中通过形态学、多基因系统发育和生态学证据、线条图及照片对这些物种进行了记录，并与相似物种进行了比较。还提供了一份中国剧毒鹅膏菌物种的检索表。
