Dimorphococcus is a genus of fresh water green algae in the family Scenedesmaceae.

[2] It is found as a component of the phytoplankton of freshwater ponds, lakes, and peat bogs.

[1] Dimorphococcus is usually found in small colonies of multiples of four cells, surrounded by a gelatinous mass.

[1] Dimorphococcus reproduces asexually via autospores, with four spores produced per mother cell.

The phycologist Chin Chih Jao considered it to have a different structure than other species of Dimorphococcus; accordingly, he placed it into a new genus, Dimorphococcopsis.
