Description
Size: The plants grow erect to a height of 7 cm.

The plants grow attached to stones by means of a holdfast which is irregularly cylindrical. In the upper half, the plant branches densely, sometimes about five branches arising from a single middle segment. Further branching is mostly dichotomous, trichotomy being occasional. While the lower segments are heavily calcified. the intensity of calcification decreases towards the upper segments. The lower 2 or 3 segments are cylindrical or subcuneate, while the other segments are trapezoidal. The uppermost 1 or 2 segments are comparatively much smaller and cylindrical or cuneate in appearance.

Anatomically there is a central medulla composed of vertically running medullary filaments from which arise lateral cortical filaments. Medullary filaments branch both dichotomously and trichotomously. Cortical filaments are made of 2 to 3 layers of utricles. The secondary utricle bears 2 to 4 peripheral utricles. After decalcification peripheral utricles remain adherent without any separation. They are angular in surface view. At the nodal region, three filaments fuse together for a long distance before branching. Thus they exhibit an extended type of fusion.
