Images are not scaled. An individual that looks bigger than its neighbors might actually be smaller. See approximate size via the Observations section below. All images were made to fit within an area of 360px high and 200px wide.
Observations

|---|---|
| Biovolume/cell | 69.63 |
| Length: | 6-8 µm |
| Width: | 6-8 µm |
Description:
Cells are typically round and green but can be more oval in shape. Organelles are visible. 1-2 flagella may or may not be visible.
Notes:
Green Lakes: Morphotype E. In Green Lakes, might later combine with taxon #2086 into a new Chlamydomonas spp. taxon?

Secondary Description
Author: Wehr, J. D. and Sheath, R. G., (eds.), 2003
Secondary Description:
Cells are spherical, ovoid or ellipsoidal, with a cell wall, two equal flagella at the anterior pole and two contractile vacuoles at the base of the flagella. The chloroplast is single and fills much of the cell, with a single or several pyrenoids. Stigma is generally single. Asexual reproduction is by zoospore formation within the mother cell wall. Sexual reproduction is isogamous, anisogamous, or oogamous. Flagella not attached in an apical gullet but arising from blepharoplasts; eye-spot usually evident.
