The distribution of epiphyton algae over higher aquatic plants of different ecological groups occurring in the lake section of the Kanev Reservoir was studied for the first time. A total of 215 species of algae represented by 221 infraspecific taxa, including those containing nomenclatural types of species of 6 divisions, 13 classes, 28 orders, 49 families, and 97 genera was registered as a result of the performed investigations. It has been found that the distribution of epiphyton algae species over higher aquatic plants belonging to different ecological groups is non-uniform. On submerged plants, the number of algae species and their infraspecific taxa, their genera, families, orders, and classes, as well as the quantitative indices of phytoepiphyton development were essentially higher than those on plants belonging to the other ecological groups.
