The last two fibrous zones differ only in coloration, but show the same orientation of fibers or even their continuation. Generally, fibers are perpendicular to the dRAF zone, as in TD region in other corals discussed here (

). Similarly, as in the longitudinal sections of the above described corals, the undulating course of the RAF in radial and longitudinal directions makes the dRAF visible only in some surfaces. In higher magnification, extremely fine (ca. 2 µm long), regular constrictions of “strands” are visible; however, perhaps because of the standard (not ultrathin) thickness of the section, it cannot be clearly stated whether constrictions correspond to regular alternations of transparent colorless and more opaque brownish layers as in other corals. Also inconclusive in this respect were observations in MFM, however, similarly as in other corals investigated, only the areas of brownish “strands” exhibited bright greenyellow fluorescence (

In the longitudinal direction “strands” show the alternation of zones more and less susceptible to etching. In places this alternation is very dense and regular (every 2 µm), and occasionally are less regular with wider zones more susceptible to etching (ca. 10 µm and more).

At higher magnifications, fibers that form ridges or are visible on the bottom of hollows exhibit a lumpy texture. Polished (but not etched) sections prepared for use in AFM, show very small and shallow grooves, difficult to discern under low magnification of a dissection scope. AFM images of these hollows reveal aggregations of grains that are ca.
