Monosiphonic colonies composed of a mass of branches and stems, irregularly branched in several planes and with anastomoses, up to 90mm in diameter, with the appearance of closely knitted net. Hydrothecae arranged in decussate pairs forming four longitudinal rows of hydrothecae. Hydrothecae immersed into the branches for approximately one-quarter of their volume and strongly curving outwards. Adcauline hydrothecal wall with a considerable free portion, adnate to internode for ca half or slightly more of its length. Free part of adcauline wall straight or slightly convex; abcauline wall concave. Hydrothecal aperture circular and tilted downwards; rim even and usually with numerous renovations. Female and male gonothecae present, both inserting individually at hydrothecal base. Female gonotheca urn-shaped; basal part ovoid, widening distally, apex contracted into a short neck bearing the aperture. Male gonotheca fusiform, with a distal, cone-shaped neck provided with a small, circular aperture.
Gonothecae with a few striae at base of neck.
Species had been found at depths 15 to 640 m on stony bottoms (Ref. 7414). Fertile colonies are found in February (Ref. 7414).
