Abstract

Sexual reproduction and mating system of the freshwater diatom Ulnaria acus (Bacillariophyta) was described for the first time. Mating system of the species includes, apparently, only heterothallic way of reproduction: during the three-year observation period neither male nor female clones have shown the ability to reproduce homothallically. The type of sexual reproduction is cis-anisogamous; in many details it similar with reproduction of closely related species Ulnaria ulna, Tabularia fasciculata, and Tabularia tabulata
