Microspora is a genus of green algae in the family Microsporaceae. Microspora was first named by Gustave Thuret in 1850. The name was used by Arthur Hill Hassall earlier in 1843, for another genus, but Thuret's genus has been conserved over Hassall's.
Description
Microspora consists of uniseriate, unbranched filaments. Cells are cylindrical, quadrate or slightly swollen. The cell wall consists of two overlapping, "H-shaped" halves, often visible at the end of filaments where cells have broken off. The cell contains a single, parietal chloroplast which is perforated to form a fine or coarse net; the chloroplast has no pyrenoids.
Reproduction occurs asexually and sexually, via biflagellate zoospores or isogametes.
