Staurastrum Meyen

Cells are always solitary, radially symmetrical and divided in 2 semicells. In end view cells are tri-pluriradiate, rarely biradiate. Cell wall porous and smooth or ornamented with spines, granules, teeth or verrucae. Cells often surrounded by spherical, mucilaginous envelope, especially in planktic species.
