在泰国和越南对商业葡萄栽培品种、野生葡萄科和楝科（Sabiaceae）上的锈菌进行了调查，这些品种是葡萄叶锈病（GLR）真菌的潜在替代宿主。使用内转录间隔区2和大亚基rRNA基因（D1/D2区域）进行的分子系统发育分析和形态学检查证实，分布于东南亚和澳大利亚的GLR真菌与东亚和美洲涉及GLR的新泡霉属物种不同。因此，东南亚-澳大拉西亚GLR真菌被认定为新藻类新种，命名为N.热带。泰国Meliosma种的两种真菌是Neophysopella种的无性变型。 M 上的一种寄生。单叶和M. simplicifoliasubsp.fordii 以前被命名为 Aecidium wareoense，新名称为 N. wareoensis，是为此提出的。另一个关于M。泰国的 arnottiana 在系统发育和形态学上与所有其他 Meliosmarust 真菌不同，因此，它被认为是一个新物种，N。斯里普门西斯。泰国蛇葡萄科(Ampelocissus araneosa)上的一种真菌在形态上与喜马拉雅山爬山虎(Parhencissus semicordata)(葡萄科)的Phakopsora cronartiiforms相似。然而，前者的真菌与后者的不同之处在于产生具有迷宫状表面结构和圆锥形突起的特征性尿孢子。因此，它被认为是一个新物种，N。多伊普亚种。
Rust fungi on commercialVitiscultivars, wild Vitaceae, andMeliosma(Sabiaceae), potential alternate hosts of a grapevine leaf rust (GLR) fungus, were surveyed in Thailand and Vietnam. Molecular phylogenetic analyses using the internal transcribed spacer 2 and the large-subunit rRNA gene (D1/D2 region) and morphological examinations confirmed that the GLR fungus distributed in Southeast Asia and Australasia is distinct fromNeophysopellaspecies involved in GLRs in East Asia and the Americas. Therefore, the Southeast Asian-Australasian GLR fungus is recognized as a newNeophysopellaspecies and named asN. tropicalis. Two fungi onMeliosmaspecies in Thailand were aecial anamorph ofNeophysopellaspecies. One parasitic onM. simplicifoliaandM. simplicifoliasubsp.fordiiwas previously named asAecidium wareoense, and a new name,N. wareoensis, is proposed for it. Another onM. arnottianain Thailand was phylogenetically and morphologically distinct from all otherMeliosmarust fungi, and, therefore, it is recognized as a new species,N. sriphumensis. A uredinial-telial fungus onAmpelocissus araneosa(Vitaceae) in Thailand was morphologically similar toPhakopsora cronartiiformisonParthencissus semicordata(Vitaceae) in the Himalayas. However, the former fungus was distinct from the latter in producing characteristic urediniospores with labyrinthiform surface structure and cone-shaped projections. It is, therefore, recognized as a new species,N. doipuiensis.
