Trichosarcina polymorpha is a species of alga. Its life cycle includes a uniseriate Hormidium-like phase; a pluriseriate stage and finally a chain of sarcinoid packets which may dissociate. The cells are uninucleate with a parietal chloroplast and single pyrenoid. Quadriflagellate zoospores are produced by cells of the pluriseriate and sarcinoid stages.
