Radaisia is a genus of coccoid cyanobacterium comprising about 10 identified species.[1] It is a colonial cyanobacterium, the bacteria initially forming a round to irregularly shaped flat group of gelatinous or crustose cells attached to the substrate from which arise rows of pseudofilamentous cells in mucilagionous sheaths perpendicular to the initial colony.[1][2] Apical cells of the pseodofilamentous sheaths are elongate compared to proximal cells in the sheath.[1] Cell division in the genus is notably irregular, although usually perpendicular to the axis in the pseudofilament.[1] The cells are light blue-green to reddish purple in color.[1]
