Species:

Note: The species nearly always grows as an epiphyte on Ascophyllum. It is very dark red (blackish) and normally grows to between 5 and 10 cm. It is densely branched in a pseudo-dichotomously way with relatively stiff branches, making it look bushy. The axes have relatively short and wide segments with 12-24 periaxial cells, and with no cortex. Normally the central cell axis, composed of round cells, is visible through the periaxial cell cover
