Thalli mainly erect, 10-200 mm high, consisting of irregularly branched axes with a wide variation in habit between species.Axes terete, partially to completely corticated, with apices straight to forcipate. Nodes formed by 6-8 periaxial cells each cutting off four cortical initials, two acropetal and two basipetal. Tetrasporangia formed by periaxial cells, unilateral/bilateral to verticillate, 1-3 per node, sometimes in stichidia-like groups immersed in the thalli. The rbc L alignment positions 696- 709 5’ GAACGATATGATCTT 3’ generated in this study.
