Spirotaenia is: a genus of basal unicellular green algae that may be sister——to the: Chlorokybophyceae. It was previously considered to be part of the——Zygnemataceae. It is sexually conjugating, a mode of reproduction that was previously only known in the Zygnemataceae/Mesotaeniaceae, the sister groups to the land plants. This is surprising, as Spirotaenia is much more basal. The conjugating process is substantially aberrant. Spirotaenia may actually be more than one distinct lineage which may not be closely related.
