Tar spot is a prevalent fungal disease characterized by shiny black spots on the leaves, stems, and fruits of various plants. It is typically caused by members of the family Phyllachoraceae, which consists of biotrophic and obligate plant parasitic fungi. During field investigations of tar spot fungi in Sichuan Province, China, 70 fungal samples associated with tar spots belonging to the family Poaceae were collected from 13 different locations. Through morphological studies and multi-locus phylogenetic analysis of combined ITS, SSU, and LSU datasets, the collected samples were classified into eight species. Among these, five were identified as new species (, , , , and ), and two represented new host records (, ). The new species are accompanied by descriptions and illustrations, while their characteristics are discussed in relation to comparable taxa. Additionally, is synonymized under . These findings enhance our understanding of tar spot fungi in Sichuan and, given that species are important pathogens of plants in the Poaceae family, establish a foundation for further research to better understand their potential impacts on agriculture and the local ecology.
煤炱病是一种常见的真菌病害，其特征是在各种植物的叶片、茎和果实上出现有光泽的黑色斑点。它通常由格孢腔菌科的成员引起，该科由活体营养型和专性植物寄生真菌组成。在中国四川省对煤炱病菌进行田间调查期间，从13个不同地点采集了70个与禾本科植物煤炱病相关的真菌样本。通过对ITS、SSU和LSU数据集进行形态学研究和多位点系统发育分析，将采集的样本分为8个物种。其中，5个被鉴定为新物种（、、、、和）和2个代表新的寄主记录（、）。新物种附有描述和插图，并与可比类群讨论了它们的特征。此外，被归为的异名。这些发现增进了我们对四川煤炱病菌的了解，鉴于物种是禾本科植物的重要病原体，为进一步研究以更好地了解它们对农业和当地生态的潜在影响奠定了基础。
