Morphological description (show/hide)
| Mass of anastomosing tubes, each about 1mm diameter, dense coormus with some space between tubes (<2mm), cushion shaped, 2x3cm | | yellowish | | beige | | No oscules visible macroscopically | | Soft | | Smooth | | Tangential layer of triactines, irregularly orientated, forming walls of tubes. Actines of the tangentially orientated triactines sometimes overlap, so that a few triactines appear to be stacked above each other, but not more than five. Tube walls are 20-40 um thick. Only rarely are the actines of triactines aligned parallel to each other, in which case they form sub-hexagonal to hexagonal pattern. Triactines are not densely arranged in the tube wall. The skeleton is uniform throughout the cormus. | | The spicular skeleton consists only of one type of regular cylindrical triactines (actines: 114-(159.6)-200x14-(16.3)-20um), with no zonation and/or differentiation within the cormus observed. Actines of the triactines are sometimes slightly undulated in their distal part and some possess blunt tips. A few triactines show a bent tip on one of their actines. Numerous smaller triactines, with more conical actines and sharp, pointed tips, are irregularly scattered between larger triactines. These small triactines are young, growing spicules. |
