For the first time Anabaena sedovii KossInsK.(Nostocales, Cyanobacteria) is recorded from the lower of Yenissei River near Igarka city (East Siberia) and isolated to monospecific culture.Morphological studies were performed on short-term cultures.The size and shape of vegetative cells, size akinetes and heterocytes as well as position of akinetes of our isolate under culture conditions almost correspond to features of nature populations as described by Kosinskaya.New further diacritical features such as double and triple adjacent intercalar heterocytes, terminal heterocytes, short distance between heterocytes and occurrence of gas vesicles observed in this study extended our knowledge on taxonomy and distribution of the member of subgenera Dolichospermum.
