Diagnosis:
Type species: Gloeobacter violaceus Rippka et al., 1974. - Monospecific genus.
Descriptions:
Komárek & Anagnostidis (1998): Cells solitary or aggregated in irregular groups, widely oval or rod shaped, surrounded by narrow, delimited gelatinous envelopes, containing one or more ensheathed cells. Cells non motile.
Komárek (1992): Unicellular; cells solitary or in irregular groups, rod- shaped or widely oval up to almost spherical, with thin, fine and indistinct or multilayered sheaths around the cells and helding sometimes more cells together. Immotile. Cells with almost colour less content and solitary granules, in masses violet. Thylakoids and phycobilisomes absent, a cytoplasmatic membrane, which follows the contour of the cell wall, is the only unit membrane system in the cell. GC-content of the DNA = approx. 65 mol. percent. Without involution cells.

data:
Reproduction strategies, life cycles,
cell division:
Komárek & Anagnostidis (1998): Cell division by simple binary transverse fission, perpendicular to the long axis of the cell. Reproduction
probably by liberation of solitary ensheathed cells or small groups of cells.
Komárek (1992): Reproduction by the simple binary transverse fission, perpendicularly to the long axis of cells.
