The freshwater cyanobacterium Raphidiopsis raciborskii is an invasive species that was originally described as tropical and now widely distributed in temperate regions. current taxonomic position established based on a multilevel approach with the morphological description of natural populations well their ultrastructural, physiological molecular characterization. practical problem identifying this morphology trichome environment can vary considerably during population growth. aim study to investigate variability R. its blooming floodplain lake Middle Danube (Europe). In both cases, only straight trichomes were found. Young one or two acuminate ends without heterocytes, referred primary filaments, be exclusively monodominant at beginning bloom formation remain dominant throughout year, leading confusion. mature populations, different forms secondary filaments may differ size number akinetes heterocytes formed trichomes. correct identification early detection freshwaters extremely important for successful control spread potentially toxic species.
