Climate / Range
Colonies formed by a mass of stems and branches up to 13 cm in diameter. Branching frequent and irregular, with frequent anastomoses, giving the colony a compact appearance. Hydrothecae arranged in decussate pairs, forming four longitudinal rows. Hydrotheca small, with a small part immersed into the branch, cylindrical, more or less abcaudally directed. Adcauline hydrothecal wall adnate to internode for ca seven-eighths to one-half of its length. Free adcauline wall straight, or slightly concave or convex. Abcauline hydrothecal wall concave or straight. Hydrothecal aperture laterally depressed, resulting in the presence of both an adcauline and an abcauline cusp; the latter sometimes much better developed than the former. Hydrothecal diaphragm mushroom-shaped.
Eurybathic species found on bottoms of small rocks with red algae, formed by bryozoans, hydrozoans, sponges, alcyonarians and ascidians; bottoms of pebble and gravel, mud with stones (Ref. 7414). Found in gonothecae in January, February and December. Fertile colonies were found in January to March and May to June (Ref. 7414).
