: This species is unicellular, nonmotile, and spherical to slightly tetrahedral or elliptical in shape. The cell wall appears to radiate, and has a thick layer of platelet-like calcite crystals imbedded in a gelatinous sheath. A chloroplast located in center of the cell contains a pyrenoid. The cells are 20-30 μm in diameter.
