FIGURE 7. Orectopora flabellum n. gen., n. sp. Details of colony morphology. A, B, E, H, holotype colony; C, D, F, G, I, J, specimen GLD4–08, Stn 151. A, B, E, apical, oblique-abfrontal and abfrontal views, respectively, of middle lobe (fascicle) in Fig. 7E, showing apparent roof forming in axil between what will become two fascicle lobes; note relatively large pseudopores in neanic calcification of abfrontal wall in B and E; C, F, two views of a small fascicle showing autozooidal apertures adjacent to concave frontal face of lobe (on right), between which are larger developing chambers (either autozooidal or reproductive), and, along convex abfrontal face (on left), a row of mostly kenozoidal openings (and perhaps some incipient autozooid buds); D, G, J, magnified sequence of images showing the largest developing chamber in C and F, and ultrastructural wall fabric; H, reversed (frontal) view of fascicle tip in E; I, frontal view of chamber in D, G, J. Scale bars: A, B, E, H, 200 µm; C, F, 150 µm; D, I, 50 µm; G, J, 20 µm.
