Description
Size: Diameter 25-90 µm.

Color: Yellow brown.

Girdle view: Cells in close set chains; cells straight or slightly curved. Bands distinct and collar shaped. Valves flat or slightly concave. Chloroplasts rounded; more or less lobed or cleft plates each with a distinct pyrenoid.
Valve view: Valve structure visible with LM; process distinct; external part a curved tube, one end connected with a labiate-shaped internal part and the other end in touch with the external valve surface (EM). Indentation close to the process probably giving space for process of adjacent cell. It is a phytosynthetic species.

Reproduction is general for group: both sexual and asexual.
