Abstract

The phylogeny and taxonomy of powdery mildews, belonging to the genus Erysiphe, on Lonicera species throughout the world are examined and discussed. Phylogenetic analyses revealed that sequences retrieved from Erysiphe lonicerae, a widespread powdery mildew species distributed in the Northern Hemisphere on a wide range of Lonicera spp., constitutes a complex of two separate species, viz., E. lonicerae (s. str.) and Erysiphe ehrenbergii comb. nov. Erysiphe lonicerae occurs on Lonicera spp. belonging to Lonicera subgen. Lonicera (= subgen. Caprifolium and subgen. Periclymenum), as well as L. japonica. Erysiphe ehrenbergii comb. nov. occurs on Lonicera spp. of Lonicera subgen. Chamaecerasus. Phylogenetic and morphological analyses have also revealed that Microsphaera caprifoliacearum (≡ Erysiphe caprifoliacearum) should be reduced to synonymy with E. lonicerae (s. str.). Additionally, Erysiphe lonicerina sp. nov. on Lonicera japonica in Japan is described and the new name Erysiphe flexibilis, based on Microsphaera lonicerae var. flexuosa, is introduced. The phylogeny of Erysiphe ehrenbergii and E. lonicerae as well as other Erysiphe species on honeysuckle is discussed, and a survey of all species, including a key to the species concerned, is provided.

金银花属金银花复合体的分类与系统发育。
对世界各地忍冬属丹毒属粉霉菌的系统发育和分类学进行了研究和讨论。系统发育分析表明,从分布在北半球广泛的忍冬属植物上的广泛分布的白粉菌中检索到的序列构成了两个独立物种的复合体,即E.lonicerae(s.str.)和Erysiphe ehrenbergii comb。新报道金银花发生在忍冬属忍冬亚属忍冬属植物上。忍冬属(=Caprifolium亚属和Periclymenum亚属),以及L.japonica。Erysiphe ehrenbergii梳。nov.发生在忍冬亚属的忍冬属上。Chamaecerasus。系统发育和形态学分析还表明,应将细孢细孢与金银花(s.str.)简化为同义词。此外,还介绍了日本金银花上的细孢细胞菌(Erysiphe lonicerina sp.nov.),并在细孢细蜂变种flexuosa的基础上引入了新名称“细孢弹性”。本文讨论了浙江丹毒和忍冬属丹毒以及金银花上其他丹毒物种的系统发育,并对所有物种进行了调查,包括相关物种的关键。引文:Bradshaw M,Braun U,Götz M,Takamatsu S(2020)。忍冬上丹皮-忍冬复合体的分类和系统发育。真菌系统学和进化7:49-65。doi:10.3114/fuse.2021.07.03。
