摘要：Lignicolous freshwater fungi are an important ecological group that are involved in the material cycle and energy flow in freshwater ecosystems. They break down lignocellulose and soften submerged decaying wood, while their mycelium provides food for aquatic animals. This study explores the diversity of lignicolous freshwater fungi in the karst landscapes of Yunnan Province, focusing on Bamei Town, Wenshan Zhuang and Miao Autonomous Prefecture. Using both morphological examination and multi-gene analysis, this research identifies 14 new species, viz., Ascolacicola minispora, Dictyocheirospora appendiculata, Faiciphoriella hyalina, Kirschsteiniothelia distoseptata, K. longiconidiophora, Occultibambusa clavata, Ophioceras aseptatum, O. cylindrosporum, Pseudorobillarda multiguttulata, Sporidesmium filiforme, S. guttulatum, Tetraploa longiappendiculata, Thysanorea fusiformis, and Wongia flava alongside introducing four new combinations, viz., Ascolacicola coffeae (= Ascotaiwania coffeae), Ascol. mitriformis (= Ascot. mitriformis), Ascol. sawadae (= Ascot. sawadae), and Ascol. uniseptata (= Triadelphia uniseptata). The sexual morph characteristics of Faiciphoriella are also provided. Furthermore, the study reports on eight new geographical records for China and identifies four species encountered in freshwater habitats for the first time. This study through detailed morphological and DNA analyses to investigate the species diversity of lignicolous freshwater fungi in karst regions, which will help us understand the microfungal diversity and carry out conservation efforts in these unique ecosystems.
