A new locality of Chara rudis has been found in the Ivano-Frankivsk Region (Ukrainian Carpathians) in summer 2008. It forms charophyte single-species meadows in a freshwater pond at a depth of 0.3–0.5 up to 1 m on silt but on solid substrate with a surface cover of 75–95%. It is the first finding of this alga in Ukraine. The specimens are described; distribution and ecology of C. rudis as well as its taxonomical status are discussed.

Keywords: Chara rudis, Charales, Ukrainian Carpathians, Ukraine
