Dimorphococcus is a genus of freshwater green algae belonging to the family Scenedesmaceae. It is commonly found in the phytoplankton of freshwater ponds, lakes, and peat bogs, although it is typically not very abundant. Dimorphococcus forms small colonies composed of multiples of four cells, which are enveloped in a gelatinous mass. These cells are connected to each other by mucilaginous strands originating from the mother cell wall. They exhibit a kidney-shaped to heart-shaped morphology, ranging from 10 to 25 μm in length and 3 to 8 (occasionally up to 15) μm in width. Each cell contains one nucleus and a parietal chloroplast with one or more pyrenoids. The algae reproduce asexually through the formation of autospores, with four spores produced per mother cell. These autospores are released through a lateral tear in the mother cell wall. After release, the empty cell wall gradually breaks down.
