Synura Ehrenberg (ref. ID; 1618)

Synuraceae (ref. ID; 7657)

Synonym Synuropsis Schiller

[ref. ID; 1618]
Spherical or ellipsoidal colony composed of 2-50 ovoid individuals arranged radially; body usually covered by short bristles; 2 chromatophores lateral; no stigma; asexual reproduction of individuals is by longitudinal division; that of colony by bipartition; cysts spherical; fresh water. (ref. ID; 1618)

[ref. ID; 3490]
The cells are ovoid to be rounded broadly in the anterior end without an eye-spot and are radially united to form a spherical or ovoid colony with a gelatinous substance. The periplast of the cell is covered with siliceous scales having minute spines. (ref. ID; 3490)
