The distribution of epiphyton algae over higher aquatic plants of different ecological groups occurring in the river section of the Kanev Reservoir was investigated. A total of 206 species of algae represented by 215 infraspecific taxa, including those containing nomenclatural types of species of 7 divisions, 14 classes, 29 orders, 45 families, and 78 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 was essentially higher than that on plants belonging to the other ecological groups.
