Tetrasporaceae
The Tetrasporaceae are a family of green algae, specifically of the Chlamydomonadales. They are found in freshwater habitats.
Algae in the Tetrasporaceae are distinguished by having two or more pseudocilia per cell, which are described as "rigid cytoplasmic processes" that project outwards. Cells are borne in microscopic or macroscopic colonies, and these colonies typically consist of a gelatinous matrix in which the cells are embedded near the periphery, typically in twos, fours, or eights.
Colonies may grow when their cells divide into two, four, or eight new cells. Asexual reproduction occurs by the formation of zoospores.
