ABSTRACT Podosphaera tridactyla (s. lat.) is a powdery mildew species occurring on a wide range of Prunus spp. almost worldwide. We have investigated the phylogeny of the Po. tridactyla complex, with special emphasis on potential aspects of cryptic speciation. The results suggested that Po. tridactyla represents a species complex consisting of at least 12 different species. Based on detailed morphological examinations and molecular sequence analyses, we propose dividing Po. tridactyla s. lat. into 10 species, encompassing 7 new species (Po. ampla, Po. pruni-avium, Po. pruni-cerasoidis, Po. prunigena, Po. pruni-lusitanicae, Po. prunina, and Po. pruni-japonicae) and 3 known species (Po. longiseta, Po. salatai, and Po. tridactyla s. str.). Oidium passerinii on Pr. laurocerasus is confirmed as a synonym of Po. tridactyla s. str. Epitypes are designated for Po. tridactyla and Oidium passerinii.

形态系统发育分析表明 Podosphaera tridactyla 构成一个物种复合体

摘要 Podosphaera tridactyla (s. lat.) 是一种白粉病菌，广泛存在于李属属植物上。几乎全世界。我们已经研究了 Po 的系统发育。tridactyla 复合体，特别强调神秘物种形成的潜在方面。结果表明，Po。tridactyla 代表由至少 12 个不同物种组成的物种复合体。基于详细的形态学检查和分子序列分析，我们建议划分 Po。三趾动物 s. 纬度 分为10种，包括7个新种（Po. ampla、Po. pruni-avium、Po. pruni-cerasoidis、Po. prunigena、Po. pruni-lusitanicae、Po. prunina和Po. pruni-japonicae）和3个已知种（Po. longiseta、Po. salatai 和 Po. tridactyla s. str.）。Oidium passerinii 上 Pr。laurocerasus 被确认为 Po 的同义词。三趾动物 s. 海峡 表型是为 Po 指定的。tridactyla 和 Oidium passerinii。
