Description
Cells 16-27 x 18-22 nm, broad rounded to cylindrical to oviform, cell wall thin with a small rounded papilla, with two flagella about as long as the cell. Chloroplast cup-shaped, parietal and massive, the chloroplast surface with fine ridges mostly parallel to the cell axis, 3-8 discontinuous pyrenoids, irregularly distributed; eyespot pale red, elliptic to narrowly elongate in an anterior position; many (up to 20) contractile vacuoles, distributed over the cell surface, nucleus in central or slightly anterior position. Asexual reproduction by four (rarely two or eight) zoospores, first division true transverse without prior rotation of the protoplast. Sexual reproduction by oogamy, homothallic, proterandric; all cell divisions in gametangium successive, 16 spermatozoids formed in gametangium; spermatozoids 4-6 x 3-5 nm, teardrop-shaped, without cell wall, with two flagella nearly 1.5 times as long as the cell, with two apical contractile vacuoles, chloroplast reduced, pale green, with a distinct eyespot, without pyrenoid.
