Polyedriopsis is a genus of green algae in the order Sphaeropleales. As of February 2022 [update], it contained a single species, Polyedriopsis spinulosa. [1] It is found worldwide in freshwater habitats as phytoplankton, but is rare. [1]
Polyedriopsis spinulosa consists of solitary or sometimes clustered cells, 12–25 μm in diameter. They are four- or five-sided with concave sides; the corners are rounded off and bear a tuft of 3-10 thin tapering spines, 25–50 μm long. Cells are uninuclate (with one nucleus and contain a single parietal chloroplast with one pyrenoid. [1] [2]
Polyedriopsis spinulosa reproduces asexually via the formation of zoospores, of which 4 to 8 are produced per cell. Zoospores are ovate, with two flagella and a stigma. [1]
