''Pectodictyon'' consists of colonies of cells which are tetrahedral or cubic in shape. Each colony has four or eight cells in the corners, covered with mucilage and connected to each other by mucilaginous threads. These colonies may themselves be connected to other colonies to form compound colonies. The cells themselves are spherical or tetrahedral, with parietal chloroplasts with pyrenoids. Asexual reproduction occurs by the formation of autospores, which arrange themselves into the shape of the colony.<ref name=KomarekFott1983/> Sexual reproduction or flagellated life stages have not been observed in this genus.<ref name=AlgaeBase/>
Two species are known: * ''Pectodictyon cubicum'' * ''Pectodictyon pyramidale'' They can be identified by the shape of the shapes of the cells and colonies.<ref name=KomarekFott1983/>
