Pine trees play a crucial role in the forests of Sichuan Province, boasting rich species diversity and a lengthy evolutionary history. However, research and investigation on fungi associated with pine trees are insufficient. This study investigated the diversity of hyphomycetes fungi associated with pine trees in Sichuan Province, China. During the survey, we collected five specimens of hyphomycetes from branches and bark of species of . Five barcodes were selected for study and sequenced, including ITS, SSU, LSU, , and . Morphological examination and multi-locus phylogenetic analyses revealed three new species, viz. sp. nov. within Teratosphaeriaceae, sp. nov. within Kirschsteiniotheliaceae, sp. nov. within Junewangiaceae, and two known species, and within Paradictyoarthriniaceae, which are the new host records from species. , distinguished from other species in the genus by its unique morphology, has three conidial morphologies: small terminal helicoconidia, scolecoconidia with many septa, and phragmoconidia conidia. has longer spores when compared to the other species in the genus. According to phylogenetic analysis, formed an independent clade sister to and , distinguished by differences in conidial size.
松树在四川省的森林中起着至关重要的作用，拥有丰富的物种多样性和悠久的进化历史。然而，对与松树相关真菌的研究和调查并不充分。本研究调查了中国四川省与松树相关的丝孢纲真菌的多样性。在调查过程中，我们从 的树枝和树皮上采集了五个丝孢纲真菌标本。选择了五个条形码进行研究和测序，包括 ITS、SSU、LSU、 和 。形态学检查和多位点系统发育分析揭示了三个新物种，即球腔菌科内的 新种、基氏腔菌科内的 新种、June 王科内的 新种，以及类网节孢科内的两个已知物种 和 ，它们是 物种的新寄主记录。 因其独特的形态与该属其他物种相区别，具有三种分生孢子形态：小型末端螺旋分生孢子、具许多隔膜的蠕虫状分生孢子和节状分生孢子。与该属其他物种相比， 的孢子更长。根据系统发育分析， 形成了一个独立的分支，与 和 为姐妹分支，以分生孢子大小的差异为特征。
