Abstract

The phylogeny and taxonomy of Podosphaera filipendulae (including P. filipendulensis, syn. nov.) have been examined. Asian, European and North American collections were examined and the nucleotides sequences of their partial rDNA region were determined. In particular, the relationship between P. filipendulae and P. spiraeae was analysed. The results confirmed P. filipendulae and P. spiraeae as two separate, morphologically similar species. The phylogenetic analysis revealed a similar phylogeny to that of the host genera. Although ITS sequences retrieved from Asian, European and North American specimens of P. filipendulae on various Filipendula spp. are identical to sequences from P. macularis on hop, there is consistently one base substitution at the 5'-end of 28S rRNA gene between the species. This result provides evidence that the hop powdery mildew and P. filipendulae are biologically and morphologically clearly distinguished, and should be maintained as two separate species.

重新审视 Podosphaera filipendulae（菊科）的系统发育和分类。

对Podosphaera filipendulae（包括P. filipendulensis, syn.对亚洲、欧洲和北美的采集物进行了研究，并确定了其部分 rDNA 区域的核苷酸序列。特别是分析了 P. filipendulae 和 P. spiraeae 之间的关系。结果证实，P. filipendulae 和 P. spiraeae 是两个形态相似的独立物种。系统发育分析表明其系统发育与宿主属的系统发育相似。虽然从亚洲、欧洲和北美的 Filipendulae P. 在各种 Filipendula 属植物上的标本中检索到的 ITS 序列与在酒花上的 macularis P. 的序列相同，但这两个物种之间在 28S rRNA 基因 5'-end 处有一个碱基替换。这一结果证明，酒花白粉病和丝核菌在生物学和形态学上有明显的区别，应作为两个独立的物种。

期刊介绍： Mycoscience is the official English-language journal of the Mycological Society of Japan and is issued bimonthly. Mycoscience publishes original research articles and reviews on various topics related to fungi including yeasts and other organisms that have traditionally been studied by mycologists. The research areas covered by Mycoscience extend from such purely scientific fields as systematics, evolution, phylogeny, morphology, ecology, physiology, biochemistry, genetics, and molecular biology, to agricultural, medical, and industrial applications. New and improved applications of well-established mycological techniques and methods are also covered.
