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 mucilaginous 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]
Some species currently in this genus include:
