Shiraiaceae is an important family in Pleosporales (Dothideomycetes), which includes medical fungi and plant pathogens. Two hypocrellin-producing taxa, and a novel genus , typified by are treated in this article. Maximum likelihood analysis, generated via RAxML (GTR+G model), using a combined SSU, LSU, TEF1 and RPB2 sequence dataset, shows that is close to and belongs to the family Shiraiaceae. Descriptions, illustrations and a taxonomic key are provided for the genera in Shiraiaceae. morphologically differs from in having small and dark ascostromata and filiform ascospores. Production of the ascostromatal metabolites, hypocrellin A and B, were examined by HPLC and spectrophotometer. The content of hypocrellin A and B of specimen HKAS 102255 () is twice that produced by HKAS 102253 (). To clarify the relationship between and , type material of the latter was examined and provided the illustration.
银耳科是格孢腔菌目（座囊菌纲）中的一个重要科，其中包括医学真菌和植物病原体。本文研究了两个产竹红菌素的类群以及一个以[具体种名]为模式种的新属。通过RAxML（GTR+G模型）使用合并的SSU、LSU、TEF1和RPB2序列数据集进行的最大似然分析表明，[新属名]与[近缘属名]接近，属于银耳科。本文提供了银耳科各属的描述、图示和分类检索表。[新属名]在形态上与[近缘属名]不同，具有小的深色子囊座和丝状子囊孢子。通过高效液相色谱法和分光光度计检测了子囊座代谢产物竹红菌素A和B的产生情况。标本HKAS 102255（[新属名具体种名]）中竹红菌素A和B的含量是HKAS 102253（[近缘属名具体种名]）产生量的两倍。为了阐明[新属名]与[近缘属名]之间的关系，对后者的模式材料进行了检查并提供了图示。
