This is a marine species.
Plants light rosy-red, with prostrate and erect axes 140-210 µm in diam. and to 2 cm tall (Schneider et al. 2015: fig. 6A); branching pattern pseudodichotomous, rarely with a branch forming in the notches of main branches at apices (Schneider et al. 2015: fig. 6B); branches forming at intervals of 11-12 axial cells on the main axes, branches erect with straight to slightly forcipate apices (Schneider et al. 2015: fig. 6B); adventitious branches occasionally developing from periaxial cells in lower portions; uniseriate, multicellular rhizoids issued in profusion from prostrate axes and lower portions of erect axes; 0-3 straight, 2-celled spines formed at axial cell nodes and in the notches of branches, one almost always found in notches of dichotomous branches, 12-14 µm diam. and 33-39 µm long (Schneider et al. 2015: fig. 6D); distal ends of axial cells cutting off 10-12 periaxial cells, these remaining at the nodes during axial cell elongation (Schneider et al. 2015: fig. 6C); except for the first abaxial periaxial cell, periaxial cells cutting off two cortical initials acropetally and one basipetally (Schneider et al. 2015: fig. 8D); the first cortical initial cutting off one spine and one elongate cortical cell, one gland cell and one elongate cortical cell, or two elongate cortical cells; the second cortical initial cutting off one elongate acropetal cortical cell and one basipetal cortical filament; the third cortical initial cutting off one basipetal filament; basipetal filaments made up of 8-9 cortical cells in tiered files, the cells isodiametric to short rectangular in surface view, the smallest 7-8 µm diam. and 10-13 µm long, the largest 5-14 µm diam. and 20-25 µm long, these completely corticating axial cells from node to node (Schneider et al. 2015: fig. 6D & E); gland cells ovoid; gametangia and tetrasporangia not seen.
