''Deasonia'' is a single-celled organism. Young cells are ellipsoidal or ovoid, while mature cells are consistently spherical with a smooth, thickened cell wall. In young cells, the chloroplast is cup-shaped and parietal, with an off-center [pyrenoid](/source/pyrenoid); in mature cells, the chloroplast may have bifurcations and indentations and eventually forms an irregular network, with the pyrenoid in the center. Mature cells are multinucleate.<ref name=Shubert2014/>
