Hydroid stage: The main stem and alternating, primary side branches are very robust. The side branches define a single plane. The color is grey-brown. The polyps grow in pairs on both sides (subalternate) of the stem and branches. The colonies may grow to a height of 10 cm. This species may be confused with Sertularella gayi. The main difference is that the latter has alternating polyps, rather than subalternating.
Medusa stage: No information.
This hydroid seems to prefer hard rock bottom on current exposes locations.
This species is widespread on both sides of the North Atlantic ocean as well as the Mediterranean.
