Abstract

A powdery mildew was found on () in China. Phylogenetic analyses using a combination of internal transcribed spacer and 28S rDNA sequences showed that this species, which clusters as sister to , is allied to , , and . This species differs from the closely allied in the number and size of asci (3-10 asci, 55-75 × 20-40 µm versus 16-32 asci, 40-60 × 20-30 µm). This species is morphologically very similar to , but clearly differs from this species in having larger chasmothecia and colorless appendages. Therefore, the powdery mildew on is described as sp. nov.

摘要

在中国，在（）上发现了一种白粉菌。使用内部转录间隔区和28S rDNA序列组合进行的系统发育分析表明，该物种聚类为与（某物种）的姐妹群，与（其他几个物种）相关。该物种与密切相关的（另一物种）在子囊的数量和大小上有所不同（3 - 10个子囊，55 - 75×20 - 40微米，而另一物种为16 - 32个子囊，40 - 60×20 - 30微米）。该物种在形态上与（又一物种）非常相似，但在具有更大的闭囊壳和无色附属丝方面明显不同于该物种。因此，在（某植物）上的白粉菌被描述为新种（新物种名称）。
