The paper deals with phytoepiphyton taxomonic composition in the Ros River and its tributaries in June 2023. A total of 132 species were identified, represented by 134 infraspecific taxa including the nomenclature species type, from 69 genera, 45 families, 29 orders, 12 classes and 6 phyla. The species number varied from 20 to 65 across the observation sites on the main riverbed and the tributaries. Bacillariophyta prevailed at all sites, their portion in taxomonic diversity varied within 70–83%. At the level of families, Gomphonemataceae and Naviculaceae dominated at all sites. Among the leading genera, Gomphonema, Navicula, and Cocconeis were represented by the highest number of species. The Sørensen similarity coefficient between epiphytic algal communities from different sites on the Ros River and its tributaries varied between 0.26 and 0.62. The lowest coefficient was recorded for the tributaries the Kamianka River and the Protoka River, which differ significantly in aquatic vegetation patterns and human impact. The highest Sørensen similarity was observed between the unregulated section of the Ros River and the section of Bila Tserkva Middle Reservoir within the Arboretum Oleksandriia. The phytoepiphyton in the Ros River and its tributaries is marked by high taxonomic diversity and heterogeneous spatial distribution due to various effects of abiotic and biotic factors.
