Diagnostic features

Unbranched filamentous chlorophyte with cell walls consisting of overlapping H-shaped sections of variable thickness (can be difficult to see in some species). Each cell contains a single, net-like, deep green chloroplast. Red pigment is commonly visible in a lens-like cavity between cells.  Cells wider, greener and more square than in Tribonema.
