Spirotaenia condensata Brébisson in Ralfs 1848
Spirotaenia condensata, a species with a single ribbon-shaped parietal chloroplast which is twisted into a helix. This is in contrast to Tortitaenia which has a central chloroplast with radiating spiral ridges. Focus plane on the periphery of the cell which gives the impression that there are two chloroplasts. Some pyrenoids are visible. The bacteria-free space around the cell gives evidence for a mucous sheath around the cell.
