Eudorina is a paraphyletic genus in the volvocine green algae clade.

Description by GM Smith (1920, p 95):[2] Eudorina colonies typically consist of 16, 32 or 64 cells, each of which is similar to Chlamydomonas reinhardtii.

These cells are bedded within an extracellular matrix composed of glycoproteins.

[3] During development, each Chlamydomonas-like cell undergoes several rounds of division to form plakeas, which then invert to form daughter colonies before hatching out of the mother colony.
