(, ) is a monotypic genus with a previously unknown systematic position. In this report, two new species are proposed, and These new taxa are proposed based on morphological characteristics evident via light microscopy and molecular data. Multi-locus phylogenetic analyses (ITS rDNA, nrLSU rDNA, , and ) show that specimens recently collected in Yunnan Province, China are closely related to . Both new species and known species were discovered repeatedly in their asexual developmental form exclusively on twigs of spp. (). This indicates a host specificity of spp. for species of .
（ ）是一个单型属，其系统位置以前未知。在本报告中，提出了两个新物种， 和 。这些新分类单元是基于通过光学显微镜和分子数据明显可见的形态特征提出的。多位点系统发育分析（ITS rDNA、nrLSU rDNA、 和 ）表明，最近在中国云南省采集的标本与 密切相关。新物种和已知物种均仅在 属植物（ ）的嫩枝上以无性发育形式反复被发现。这表明 属植物对 属物种具有宿主特异性。
