During a survey of hypoxylaceous fungi in Medog county (Tibet Autonomous Region, China), three new species, including , , and , were described and illustrated based on morphological and multi-gene phylogenetic analyses. is characterized by its yellow-brown stromatal granules, light-brown to brown ascospores, and frequently indehiscent perispore. is morphologically and phylogenetically related to but differs in having larger ascospores with straight spore-length germ slit and conspicuously coil-like perispore ornamentation. shows morphological similarities to but differs in having Amber (47), Fulvous (43) and Sienna (8) KOH-extractable pigments and larger ascospores with straight spore-length germ slit. The multi-gene phylogenetic analyses inferred from the datasets of ITS-RPB2-LSU-TUB2 supported the three new taxa as separate lineages within . A key to all known species from China and related species worldwide is provided.
在对中国西藏自治区墨脱县的缺氧真菌进行调查期间,基于形态学和多基因系统发育分析,描述并图示了三个新物种,包括[物种名称1]、[物种名称2]和[物种名称3]。[物种名称1]的特征在于其黄褐色的基质颗粒、浅棕色至棕色的子囊孢子以及通常不开裂的周壁。[物种名称2]在形态学和系统发育上与[物种名称1]相关,但不同之处在于其具有更大的子囊孢子,孢子长度方向的萌发缝为直的,且周壁有明显的螺旋状纹饰。[物种名称3]与[物种名称1]在形态上有相似之处,但不同之处在于其具有琥珀色(47)、黄褐色(43)和赭色(8)的氢氧化钾可提取色素,以及更大的子囊孢子,孢子长度方向的萌发缝为直的。从ITS-RPB2-LSU-TUB2数据集推断的多基因系统发育分析支持这三个新分类单元为[属名]内的独立谱系。提供了中国所有已知[属名]物种及世界范围内相关物种的检索表。
