Freshwater fungi consist of a highly diverse group of organisms in freshwater habitats worldwide. During a survey of fungal diversity in freshwater habitats across different regions of Jiangxi Province, China, four freshwater fungi were collected. To study their phylogenetic relationships, the internal transcribed spacer (ITS1-5.8S-ITS2), large subunit (28S, LSU), small subunit (18S, SSU), and RNA polymerase II subunit () genes were selected for phylogenetic analyses. Based on morphology coupled with phylogenetic analysis, these strains were confirmed to belong to , , and . Among them, three fungi were confirmed as the new species, namely, (Pleurotheciaceae), (), and (Pseudodactylariaceae). One species was identified as (Pleurotheciaceae), a new record of this species in China. All species were compared with other similar species, and detailed descriptions, illustrations, and phylogenetic data were provided.
淡水真菌是全球淡水生境中一类高度多样化的生物。在中国江西省不同地区的淡水生境真菌多样性调查中，采集到了四种淡水真菌。为研究它们的系统发育关系，选择了内转录间隔区（ITS1 - 5.8S - ITS2）、大亚基（28S，LSU）、小亚基（18S，SSU）和RNA聚合酶II亚基（）基因进行系统发育分析。基于形态学并结合系统发育分析，这些菌株被确认为属于、和。其中，三种真菌被确认为新物种，即（侧盘菌科）、（）和（拟指孢霉科）。一种物种被鉴定为（侧盘菌科），是该物种在中国的新记录。所有物种都与其他相似物种进行了比较，并提供了详细的描述、插图和系统发育数据。
