Abstract

The fungal family Botryosphaeriaceae, which includes genera such as , , and , comprises species commonly associated with woody plants such as endophytes, pathogens, and saprophytes. The Xizang Autonomous Region of China, known for its rich forest resources, harbors significant fungal diversity. However, limited research has been conducted on plant-disease-associated fungi in this region. In this study, we employed morphological characteristics and molecular phylogenetic analyses of the internal transcribed spacer region of rDNA (ITS), the ribosomal large subunit (LSU), the translation elongation factor 1-alpha () gene, and the partial beta-tubulin () gene to identify fungal species. As a result, two new species, sp. nov. and sp. nov., are proposed and described herein. Additionally, . , . , . , . , . , . comb. nov., and . are reported for the first time in Xizang. Our findings contribute to advancing the knowledge of fungal biodiversity in Xizang's high-altitude ecosystems.

摘要

葡萄座腔菌科真菌家族，包括如、和等属，包含通常与木本植物相关的物种，如内生菌、病原体和腐生菌。中国西藏自治区以其丰富的森林资源而闻名，拥有丰富的真菌多样性。然而，该地区与植物病害相关的真菌研究有限。在本研究中，我们利用核糖体DNA的内部转录间隔区（ITS）、核糖体大亚基（LSU）、翻译延伸因子1-α（）基因和部分β-微管蛋白（）基因的形态特征和分子系统发育分析来鉴定真菌物种。结果，本文提出并描述了两个新物种，新种和新种。此外，、、、、、、新组合，以及在西藏首次被报道。我们的研究结果有助于增进对西藏高海拔生态系统中真菌生物多样性的了解。
