Chamaedoris auriculata Børgesen 1933: 5-9, figs. 3-5

Plants dark green, erect, brush-like, 3-8 cm tall, often in groups. A single-celled stipe with annular constrictions bears a flat, auriculate (ear- or fan-shaped) capitulum made up of many adherent filaments; basal capitulum cells 120-250 µm in diameter, apical capitulum cells (45-) 60-110 (-140) µm in diameter.. Structure similar to C. delphinii, but see Leliaert et al. (2007) for details.
