Chain

Description
Size: Diameter (apical axis) 25-78 ┬Ám.

Cells are cylindrical with a broad elliptical cross-section. They are connected to straight chains with larger elliptical to hexagonal apertures between the cells. Valves are flat to slightly concave with a short mantle and a small central process. External part of central process laterally flattened; internally visible as a slit. Setae arise a bit inside of the valve margin at the apical poles. They have a short basal part and then are joined with those of the adjacent cell. They are quadrangular in cross-section with tiny spines at the edges. Setae are usually bent towards the nearest end of the chain. One part of the setae is almost parallel to the apical axis whereas the other part is strongly diverging so that it is nearly parallel to the transapical axis. Cells contain numerous small chloroplasts which are also present within the strong setae. Resting spores are formed inside lateral auxospores.
