The classification and physiology of the zoosporic plant-pathogen Olpidium brassicae and its relationships with the closely-related species are often confusing. This review focuses on these species and intends to differentiate them based on the literatures published since the discovery and establishment of the species by Woronin in 1878 under the name of Chytridium brassicae to current molecular era. The goal of this review is to help researchers better understand the taxonomy, the host range, and the potential role in plant health of O. brassicae-related species. To reach the goal, we reviewed the rationales behind the creation or reduction in synonymy of the different names for O. brassicae and its allied species in order to elucidate the evolution of the species concept on them based on the traditional morphological studies. Furthermore, the studies by molecular biology methods improve our knowledge and perspectives on O. brassicae and its host specificity. In particular, we clarify the differences between O. brassicae and Olpidium virulentus, and propose potential new research avenues. We therefore hope that this review will give a better perspective on Olpidium spp. and their potential role in the root microbiome of plants in natural environments and in agricultural settings.
游动孢子植物病原菌芸苔油壶菌的分类、生理学及其与近缘物种的关系常常令人困惑。本综述聚焦于这些物种，旨在依据自1878年沃罗宁以芸苔壶菌之名发现并确立该物种以来直至当前分子时代所发表的文献对它们进行区分。本综述的目的是帮助研究人员更好地理解芸苔油壶菌相关物种的分类学、寄主范围及其在植物健康中的潜在作用。为实现这一目标，我们审视了为芸苔油壶菌及其近缘物种创造或减少同义词背后的基本原理，以便基于传统形态学研究阐明关于它们的物种概念的演变。此外，通过分子生物学方法进行的研究增进了我们对芸苔油壶菌及其寄主特异性的认识和见解。特别是，我们阐明了芸苔油壶菌与致病油壶菌之间的差异，并提出了潜在的新研究途径。因此，我们希望本综述能为油壶菌属及其在自然环境和农业环境中植物根际微生物群落中的潜在作用提供更好的视角。
