Chlorococcum Meneghini

From Greek chloros, "green"

Both ultrastructural and molecular data have revealed that Chlorococcum is polyphyletic. The morphology of the chloroplast and zoospore cell walls are different from those of other nonmotile, single-celled green algae.

Chlorococcum is unicellular with spherical or slightly oblong cells of varied size. The cells

may be solitary or in irregular clumps, sometimes forming films on moist or submerged surfaces.

The mucilage is thin and inconspicuous. Each

cell has a single cup-shaped, parietal chloroplast with a single pyrenoid.
