Sphaerozosma is a genus of green algae, specifically of the Desmidiaceae. It occurs in acidic, oligotrophic freshwater habitats and is found worldwide.
==Description== Sphaerozosma consists of cells which are flattened (and thus biradiate in apical view); the cells are attached end-to-end to form short or long filaments. At the apex of each cell there is a pair of obliquely placed, small rod-like processes; cells are attached to each other via these processes. The cell wall has pores arranged in horizontal or oblique lines. Cells are deeply constricted at the middle, forming two halves (called semicells). Each semicell has a single chloroplast with a central pyrenoid. The nucleus is at the isthmus where the two semicells are joined.
