Genus: Cell body elongated spindle in shape, straight or curved, sharply pointed at both ends;
(Guide book to the "Photomicrographs of the Freshwater Algae", 1998).
Species: Cell body spindle-shaped, moderately curved, with blunt ends, 8-17 μm long, 1.5-3.5 μm wide; a chloroplast parietal with a naked pyrenoid (invisible under photomicroscope); cell division produces 4 or 8 "autospores" (Photomicrographs of the Freshwater Algae, 1997). |

Monoraphidium litorale Hindak: Cells singular, fusiform, often attached to a subtrate or to mother cell wall remnant with one end by means of a mucous target; 22-43 micron long, 2-6 micron wide; a chloroplast pariental, trough-shaped, with a naked pyrenoid (without starch-envelope); cell division produces 4, 8 or 16 autospores (daughter cells) releasing by crosswise rupture of mother cell wall (Phtomicrog. Freshw. Alg. 16: 56, 1996)
