发现于叶下珠、苦叶下珠和叶下珠的叶、枝和茎上的白粉菌。结果表明，网状真菌是一种形态独特的真菌。添加了一种新的萌发模式的光学显微镜照片，以讨论与白粉病的其他四种萌发模式的差异。在叶下珠中发现了真菌的rDNA序列(28S和18S区)。在18S+28S树上形成了一个由Bootstrap(100%)支持的明显的单系分支，这表明该真菌是部落水平上的一个孤立的真菌类群。由于我们无法找到这种真菌的同形状态，因此提出了一种新的微孢子菌亚属来适应这种微生物。
Powdery mildew fungi found on leaves, shoots, and stems ofPhyllanthus acidus,P. amarus, andP. reticulatusproved to be a fungus having morphology unique in the Erysiphaceae. Light micrographs of a new germination pattern are added to discuss differences to other four germination patterns of the powdery mildews. The rDNA sequences (28S and 18S regions) of the fungi found onPhyllanthusspp. form a distinct monophyletic clade strongly supported by bootstrap (100%) in 18S + 28S trees, which indicates that the fungus is an isolated fungal group among the Erysiphaceae in tribal level. Because we cannot find the teleomorphic state of this fungus, a new subgenusMicroidiumof anamorphic genusOidiumis proposed to accommodate this organism.
