Triblidiaceae (Rhytismatales) currently consists of two genera: and . is the type genus and is characterised by melanized apothecia that occur scattered or in small clusters on the substratum, cleistohymenial (opening in the mesohymenial phase), inamyloid thin-walled asci and hyaline muriform ascospores. Before this study, only the type species, , had DNA sequences in the NCBI GenBank. In this study, six specimens of were collected from China and France and new ITS, mtSSU, LSU and RPB2 sequences were generated. Our molecular phylogenetic analysis and morphological study demonstrated three new species of , which are formally described here: , and . Additionally, our results indicated that that was considered to be distinct from because of its elongated, transversely-septate ascospores, is congeneric with . Therefore, we have placed in synonymy under , rendering Triblidiaceae a monotypic family.
三叉叶科(座囊菌目)目前包含两个属:[属名1]和[属名2]。[属名1]是模式属,其特征为黑色子囊盘,散生或成小簇生于基质上,具封闭子实层(在中层子实层阶段开口),无淀粉质薄壁子囊和透明砖格状子囊孢子。在本研究之前,NCBI基因库中仅有模式种[种名]的DNA序列。在本研究中,从中国和法国采集了6份[属名1]标本,并获得了新的ITS、mtSSU、LSU和RPB2序列。我们的分子系统发育分析和形态学研究表明,[属名1]有3个新物种,在此正式描述为:[新种名1]、[新种名2]和[新种名3]。此外,我们的结果表明,因具细长的横向分隔子囊孢子而被认为与[属名1]不同的[种名],与[属名1]同属。因此,我们将[种名]置于[属名1]的异名之下,使三叉叶科成为单型科。
