Plants display a reddish or red-brown hue, forming tufted and densely branched structures with an intricate base and upright branches that generally do not extend prominently beyond the rest. The branches are cylindrical and adorned with delicate, spiny twigs that tend to point perpendicularly to the main branch. These plants attach themselves using small, disk-like structures. Their growth pattern is uniaxial, with a prominent apical cell and a discernible central filament extending through the core, and a medulla that spans 2 to 3 cells in width.
