Japanese bladdernut shrub, Staphylea bumalda (Staphyleaceae), was found infected by a fungus in Prefectures of Ibaraki and Tochigi, central Japan. The fungus produced telia beneath the host epidermis and basidiospores on metabasidia emerging from the sori on the abaxial leaf surface. Probasidia were single-celled, sessile, short-cylindrical, thin-walled, and laterally free. A four-celled metabasidium arose from a probasidium by apical elongation. Apparent biotrophic nature and the basidium morphology of the Staphylea fungus suggested its taxonomic affinity to the rust genus Ochropsora. Molecular phylogenetic analyses of D1/D2 region of LSU rDNA showed that two collections of the fungus were grouped with Ochropsora ariae (type species of the genus) and O. nambuana but formed an independent clade. The fungus under consideration was, therefore, classified in Ochropsora, and a new name, O. staphyleae, was proposed for it.

在日本中部茨城县和To木县发现一种日本栗灌木灌木Staphylea bumalda（Staphyleaceae）被一种真菌感染。真菌在寄主表皮下面和从背面叶片上的sori出来的后生基底上的担子孢子下产生茎突。前鞭毛体为单细胞，无柄，短圆柱形，薄壁且侧向游离。通过根尖的伸长从前基质中产生了四细胞间基质。表观活体营养性质和的担子形态沽真菌建议其对锈属分类学亲和力Ochropsora。LSU rDNA D1 / D2区的分子系统发育分析表明，该真菌的两个集合与菜纲（该属的类型物种）和O. nambuana，但形成了一个独立的进化枝。因此，所考虑的真菌被归类为Ochropsora，并为其提议了新名称O. staphyleae。
