Popis: 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 Pinus. Five barcodes were selected for study and sequenced, including ITS, SSU, LSU, TEF1, and RPB2. Morphological examination and multi-locus phylogenetic analyses revealed three new species, viz. Catenulostroma pini sp. nov. within Teratosphaeriaceae, Kirschsteiniothelia longisporum sp. nov. within Kirschsteiniotheliaceae, Sporidesmiella sichuanensis sp. nov. within Junewangiaceae, and two known species, Paradictyoarthrinium diffractum and P. hydei within Paradictyoarthriniaceae, which are the new host records from Pinus species. Catenulostroma pini, 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. Kirschsteiniothelia longisporum has longer spores when compared to the other species in the genus. According to phylogenetic analysis, Sporidesmiella sichuanensis formed an independent clade sister to S. aquatica and S. juncicola, distinguished by differences in conidial size.
