Short description Morfologi

5 cm high. Erect stem arising from disk-shaped hydrorhiza. Stem stiff, thickest basally and gradually thinning toward the apex, up to half its length or slightly more polysiphonic, distal part monosiphonic. Branching alternate over irregular distances or quite irregular. Principal branches polysiphonic at their base, the remaining branches are monosiphonic’ (Ref. 7417). The present fragmented state of the colony does not allow the re-description of its general appearance. The colony has a discoid hydrorhiza and the stem is polysiphonic at least in the first 3 cm (the three basal most fragments of 1.4, 0.8 and 0.8 cm are polysiphonic). Polysiphonic stolons thick, more or less as main stem. Hydrothecae alternately arranged, approximately in one plane, hidden by polysiphonic development at basal part of stem. One hydrotheca per internode. Hydrotheca almost cylindrical, slightly abcaudally directed, adnate to internode for approximately two-thirds of its length. Free portion of adcauline hydrothecal wall slightly convex. Abcauline wall straight or slightly concave, mainly at its distal part. Hydrothecal aperture upwardly directed. Cusps sharp and separated by deep embayments. Rim of hydrothecal aperture with frequent and numerous renovations. Gonothecae oval, inserting at hydrothecal base. Gonothecal wall ringed, with 10 to 12 spirally arranged rings. Apical part of gonotheca with a long tube, widening distally and clearly surpassing the last ring.

Biologi     Ordlista (t.ex. epibenthic)

Known at depths of 8 to 195 m on bottoms of boulders, stones and sand. Epibiothic on holothurians and epilithic on stones (Ref. 7416).
