Powdery mildew was found on () in Jiangsu Province and Shandong Province, China. This fungus is characterized by having long conidiophore foot-cells which are straight or curved at the base, and chasmothecia with numerous appendages. Phylogenetic analysis using internal transcribed spacer sequences showed that five sequences on determined in this study and two sequences retrieved from sp. on formed an independent cluster within the clade with 58% bootstrap support. This powdery mildew differs from allied species of the clade in producing longer conidia and conidiophores with longer foot-cells, which are often curved at the base. Morphological observations and molecular phylogenetic analysis revealed a new powdery mildew species, described as .
在中国江苏省和山东省的()上发现了白粉病。这种真菌的特征是具有长的分生孢子梗基部细胞,基部直或弯曲,以及具大量附属丝的闭囊壳。使用内部转录间隔区序列进行的系统发育分析表明,本研究中测定的()上的五个序列和从()上检索到的两个序列在()分支内形成了一个独立的聚类,自展支持率为58%。这种白粉病与()分支的近缘种不同,其分生孢子和分生孢子梗更长,基部细胞通常弯曲。形态学观察和分子系统发育分析揭示了一种新的白粉病物种,被描述为()。
