Branches: Few and separated to profuse and crowded; ~7 mm across, usually >50% colony height. Morphotype plantaginea with branches 20-25 cm long, 3-5 mm across.
Apertures: Hemispherical with lower lip; calices recognizable by diagonally upward protrusion. Rows of calices sometimes spiral along branches.
Mucus: Absent.
Color: Ochre. Dries dark brown to tan. Light brown polyps.
Sclerites: Polyp armature: small flattened rods. Axial layer: purple spindles 0.13-0.5 mm long, with simple to laterally deformed ornaments. Middle layer: large transparent spindles to 2 mm long and usually thin, 0.09-0.2 mm across. Surface layer: dense torch-like clubs 0.13-0.35 mm long.
