''Coelastropsis'' consists of coenobia of cells. Cells are borne in irregular spheroidal clusters of 2, 4, 8, or 16, not surrounded by a layer of mucilage. Cells are surrounded by a thick cell wall which are covered in longitudinal ribs. The cell contains a single parietal chloroplast, with one pyrenoids.<ref name=AlgaeBase/>

''Coelastropsis'' reproduces asexually by producing autospores, where each spore develops into a cell of the new coenobium. Flagellated stages and sexual reproduction have not been observed.<ref name=AlgaeBase/>
