The lemon-shape above is the most common shape for this species of Oocystis, although they can also be seen as ovoid or ellipsoid. Cells are colonial (2-16 cells) within enlarged parental cell. Two or three generations of cells may be enclosed in this parental cell, which will enlarge to the point on appearing to be a gelatinous sheath. Cells measure 12-20µ in diameter, 16-28µ long.
