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

''Coelastropsis'' reproduces [asexually](/source/asexual_reproduction) by producing [autospore](/source/autospore)s, where each spore develops into a cell of the new coenobium. Flagellated stages and sexual reproduction have not been observed.<ref name=AlgaeBase/>
