Abstract

European members of the species-rich sect. Vaginatae of the genus Amanita are studied focusing on Central (Austria, Hungary, N Italy and Romania), Western (France) and North European (Norway) collections. The combination of a 4-locus (nrDNA ITS, nrDNA LSU, RPB1 and TEF1-α) molecular phylogenetic analysis and a morphological approach resulted in the discovery of three new species: Amanita deflexa and A. griseofulva from stirps Fulva and A. opaca from stirps Coryli. Furthermore, the albinotic white forms of A. griseofulva (f. albida) and A. opaca (f. cettoi) are formally named. As a result of the comprehensive taxonomic revision of Amanita sect. Vaginatae, 370 newly generated sequences are deposited to GenBank, and 17 species new to Hungary are reported. This study provides another step towards understanding the taxonomy and diversity of Amanita section Vaginatae in Europe.

系统发育和形态学研究揭示了欧洲姬松茸科（Amanita sect.来自欧洲的姬松茸（姬松茸科，担子菌纲

物种丰富的天南星科的欧洲成员。研究的重点是中欧（奥地利、匈牙利、意大利北部和罗马尼亚）、西欧（法国）和北欧（挪威）的藏品。结合 4 个位点（nrDNA ITS、nrDNA LSU、RPB1 和 TEF1-α）的分子系统学分析和形态学方法，发现了三个新物种：A. griseofulva 和 A. opaca。此外，A. griseofulva（f. albida）和 A. opaca（f. cettoi）的白化白色形态也被正式命名。由于对 Amanita sect.Vaginatae 的全面分类修订，370 个新生成的序列被存入 GenBank，并报告了 17 个匈牙利的新物种。这项研究为了解欧洲天南星科（Amanita section Vaginatae）的分类和多样性又迈进了一步。
