Ehrenberg ex Kützing 1844 Category: Araphid
TYPE SPECIES: Tabellaria fenestrata (Lyngbye) Kützing
Tabellaria valves are elongate with capitate ends. The valves are generally wider at the center than at the ends. A rimoportula is present in the center of the valve face. Septae are present on the numerous copulae (girdle bands). Pseudoseptae may also be present. Cells form zig-zag colonies joined by mucilage pads secreted from apical porefields.
Tabellaria is considered a close relative of Oxyneis. The two genera share the presence of septae, which may be detached in some preparations. Species within the genus are found in a range of water types, from acidic to alkaline waters.
