Cosmocladium is a colonial organism, consisting of usually up to 16 cells. Colonies may be free-floating or attached to filamentous algae. The cells are typically quite small, consisting of two identical halves called semicells, and are constricted at the isthmus where the semicells are joined. Cells are connected to each other by thin strands (bundles of microfibrils) secreted by special pores near isthmus, forming a branched network. Semicells are ellipsoid or elongate-oval in apical view, with one chloroplast per semicell each containing a central pyrenoid. The cell wall is smooth. A single nucleus is found in the center of each cell.
