Diagnostic characters. Surface cortex (including calyx surface) containing small, ornate, radiate sclerites (6, 7, and 8 rays); predominantly 6 radiates with distinctive, labyrinthlike, groove markings in the radiate projections or ornamentations (Figs. 7 C–D and 8C–D). Description. Robust treelike colonies up to several meters in height with bubblelike concentrations of autozooids (Fig. 6). Complete specimens exhibiting dense and regular accumulations of autozooid nodules or bulbs on distal or lateral branches, whereas the distal main stem and branches are usually without nodules (Fig. 6 A). Internodular surface with numerous and uniformly distributed tiny siphonozooid apertures giving the colony a granular texture (Fig. 6 D). Medulla perforated by 5–7 main stem canals in terminal ... |
