Three Parallel Rivers is one of the world's biodiversity hotspots. However, the research on myxomycetes diversity is scarce in this area. Random sampling was used to investigate myxomycetes' diversity and distribution characteristics in this area. One hundred and seventeen species, including three varieties, were obtained, belonging to 28 genera, nine families, and six orders, with Arcyria cinerea and Physarum viride being the dominant species. Moreover, four species and one variety were first reported in China. Twenty-six species and one variety were first reported in Yunnan Province. The species' most commonly utilized substrate for fruiting bodies was decaying wood, and Cribraria was the dominant genus. The species diversity was most abundant in mixed broadleaf-conifer forests. Species similarity between coniferous and broad-leaved forests was much higher than the pairwise comparison of other forest types. NMDS analysis shows that substrate and forest types had insignificant effects on myxomycetes communities, while river valley had a significant effect. The myxomycetes community similarity between river valleys is unrelated to geographical proximity.
三江并流地区是世界生物多样性热点地区之一。然而，该地区对黏菌多样性的研究较少。本研究采用随机采样方法，调查了该地区黏菌的多样性及其分布特征。共获得黏菌 117 种，包括 3 变种，隶属于 28 属、9 科、6 目，其中优势种为绒泡菌和发网菌。此外，有 4 种在中国、26 种在云南省为首次报道。子实体最常利用的基质是腐朽木材，优势属为网褶菌属。物种多样性在针阔混交林最为丰富。与其他森林类型相比，针叶林和阔叶林之间的物种相似性更高。NMDS 分析表明，基质和森林类型对黏菌群落没有显著影响，而河谷对其有显著影响。河谷间黏菌群落的相似性与地理邻近度无关。
