本研究对东亚地区致死鹅膏菌的形态特征和分子系统发育关系进行了研究。结果表明，至少有9个系统发育类群存在于该地区。其中5个与已知的形态分类群相同，包括A. exitialis，A. fuliglidae，A. subjunquillea、拟野牡丹A. subjunquilleavar.albaandA. virosa; 3个新分类群，A. fuligrandides，A. rimosaandA. pallidorosea的描述和说明在这里。剩下的一个被标记为“A.sp. 1”，因为没有发现强有力的形态学证据将其与A区分开来。subjunquilleavar.alba. A.病毒蛋白东亚，一个著名的致命有毒蘑菇最初描述来自欧洲，被证实的ITS序列和形态。另一种原产于欧洲的致命物种，A。phalloides与A.从形态学的角度来看，鹅膏菌属（Amanita oberwinklerana）属于鬼笔亚科（Phalloideae）组，但从ITS区序列和核糖体RNA基因大亚基序列分析来看，鹅膏菌属（Amanita oberwinklerana）似乎属于石竹柏组（Lancellae）。本文还讨论了东亚鬼笔亚科的分布特点及其与欧洲和北美鬼笔亚科的亲缘关系。编制了东亚鬼笔组植物种检索表。
This study investigated the morphological characteristics and molecular phylogenetic relationships among lethalAmanitaspecies occurring in East Asia. The results revealed that at least nine phylogenetic taxa exist in the region. Among them, five were identical to previously known morphological taxa includingA. exitialis,A. fuliginea,A. subjunquillea,A. subjunquilleavar.albaandA. virosa; three new taxa,A. fuligineoides,A. rimosaandA. pallidoroseawere described and illustrated here. The remaining one was labeled “A.sp. 1” because no robust morphological evidence was found to distinguish it fromA. subjunquilleavar.alba. The occurrence ofA. virosain East Asia, a well-known lethally poisonous mushroom originally described from Europe, was confirmed by both ITS sequences and morphology. Another lethal species native to Europe,A. phalloides, was determined as closely related toA. subjunquilleafrom East Asia.Amanita oberwinkleranawas treated in sectionPhalloideaefrom a morphological point of view, but appeared to be a member of sectionLepidellaby the analyses of sequences from both the ITS regions and the large subunit of nuclear ribosomal RNA gene. Distribution features of East AsianPhalloideaeand the phylogenetic relationships of these species with their counterparts from Europe and North America were also discussed. A key to species of sectionPhalloideaein East Asia is furnished.
