Instead, such cells were covered with a layer of rod-shaped bacteria. In clonal cultures, the cells gradually acquired siliceous coverings typical for this species and retained them in next generations. Phylogenetic position of R. pallida was clarified with SSU rDNA-based molecular phylogenetics, and its placement within the genus Raphidocystis despite unusual coverings structure was confirmed.
