Pseudoparenchymatous Algae

It is a thallus where the filaments are repeatedly branched and the branches are in close aggregation, giving an appearance of a parenchymatous organization. Such a thallus with a single large central (axial) filament is called uniaxial (e.g, Batrachospennun) and those with several axial filaments is known as multiaxial (e8, Polysiphonia).
