Deasonia is a genus of green algae, in the family Actinochloridaceae.[1] It is found in soils.[2]

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; 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.[2]
