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-alpha and beta-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.
