The morphological study of 22 populations of the complex Handmannia comta (Ehrenb.) Kociolek et Khursevich/ H. radiosa (Grunow) Kociolek et Khursevichfrom water bodies of different types, geographic location, and trophic status has shown a significant variability in the majority of quantitative (the valve diameter, size of central area, number of striae and marginal fultoportulae in 10 mm, number of satellite pores of central fultoportulae, number of thin costae in alveoli, number of rings of central fuloportulae, number of rimoportulae, number of punctuate rows in striae) and qualitative (the relief of central area, presence of granules on valve and branching costae among alveoli, arrangement of central processes and rimoportulae, size of alveoli, orientation of rimoportulae slit) morphological characteristics (19) and their overlapping. The obtained results have allowed the author to add to information on H. comta of H. comta, refer H. radiosa and Cyclotella balatonis Pant. to its synonymy as well as specify the ecology and distribution of H. comta.

Keywords: Bacillariophyta, Centrophyceae, complex Handmannia comta / H. radiosa, morphology, taxonomy, ecology
