Colonies have thin (up to 5 mm diameter), straight compact branches. Corallites are crowded and uniformly spaced on branch sides and ends. They have a slight development of hoods towards branch ends. They have small style-like columellae and six primary septa which are fused with the columellae. The coenosteum is covered by fine spinules. Tentacles are not extended during the day.
Uniform tan, sometimes with pinkish branch bases.
