is presented in this study as a new genus and new species based on morphological and phylogenetic evidence. This new taxon is characterized by resupinate, smooth and membranaceous basidiomata, monomitic hyphal system with clamps, colorless dendrohyphidia, variable presence of cystidia, and ellipsoid to ovoid basidiospores measuring 5-7 × 3.2-5.2 μm. The phylogenetic analyses based on the ITS1-5.8S-ITS2 (ITS) + nuclear 28S rDNA (28S) dataset of Corticiales indicated that the new taxon is nested in Punctulariaceae, separated from other genera with strong support values. Descriptions, specimen photo, and illustrations of the new taxon are provided in this study. A morphological comparison of the four genera of Punctulariaceae is given.
基于形态学和系统发育学证据，本研究将其作为一个新属和新物种进行了描述。这个新分类单元的特征是平伏、光滑且膜质的担子果，具锁状联合的单系菌丝系统，无色的树状菌丝，囊状体的存在情况多变，以及椭圆形至卵形的担孢子，大小为5-7×3.2-5.2μm。基于皮层菌纲的ITS1-5.8S-ITS2（ITS）+核28S rDNA（28S）数据集进行的系统发育分析表明，这个新分类单元嵌套在点盘菌科中，与其他属分离，支持值很高。本研究提供了该新分类单元的描述、标本照片和图示。还对点盘菌科的四个属进行了形态学比较。
