Description
Single vegetative cells spherical to oblong, 5.5-18 µm wide in mature cultures; dividing cells to 22 µm. Flat and raised packets of cells formed by vegetative division which produces 2-4 (rarely 8) daughter cells which often adhere in small groups; several generation of cells sometimes visible inside a single cell wall. One (rarely 2) chloroplast which can be lobed or asteroid; one (rarely 2) pyrenoids with large starch grains covering the hull. No extracellular matrix is present. Naked zoospores are dorsal-ventrally flattened and are of varying sizes (2-4 µm wide by up to 12 µm long); some are very flexible. Typically 4-8 zoospores produced per sporangium. Zoospores have a round posterior and either a round or pointed anterior; a small stigma, nucleus and 2 contractile vacuoles are positioned at the anterior end; no pyrenoid was observed. No caroteniod pigment was observed.
