Marthea is a genus of green algae in the family Characiaceae, containing the single species Marthea tetras. [1] It is an extremely rare genus; it has only been recorded once, [1] as freshwater phytoplankton from its original locality in the Bohemian Forest region of the Czech Republic. [2]
Marthea tetras consists of cells in colonies of four in a cross shape. Cells are spindle-shaped, with the base attached to a central mass of mucilage, while the apex of the cells are pointed. The cell wall is smooth. Cells contain one nucleus and a single, parietal chloroplast with one pyrenoid. [1]
Marthea reproduces asexually by autospores. [1] Four autospores form from one protoplast. Unusually, the autospores show amoeboid movement for some time, before settling in their usual shape and being released from the sporangium. [3]
