Pleurocapsales

Dermocarpa sp, with largest cells showing internal fission, from Phycokey.

Belongs within: Cyanobacteriia.

The Pleurocapsales are blue-green algae reproducing via multiple fission of a parental cell to form small, spherical cells (baeocytes) that are released en masse via rupture of the parent’s fibrous outer wall (Castenholz 2001).
