Figure 24 in Taxonomic classification of the reef coral family Mussidae (Cnidaria: Anthozoa: Scleractinia)

Figure 24. Favia, Diploria, and Pseudodiploria microstructure (transverse thin section): left column, whole corallite; middle column, wall; right column, columella. Favia, Diploria, and Pseudodiploria all have septothecal walls (w). In Pseudodiploria, there are also trabeculothecal components, and Pseudodiploria strigosa has abortive septa. Clusters of calcification centres (c) are well defined in Favia, moderately well defined in Diploria, and weak in Pseudodiploria; however, Pseudodiploria has better defined medial lines. Carinae are well developed in Favia, but not in the other two genera; thickening deposits are moderately developed in all three genera. A–C, Favia fragum (Esper, 1795); figured specimen = SUI122816 (FA1065), Bocas del Toro, Panama. D–F, Favia gravida (Verrill, 1868); figured specimen = YPM9085, Rio Formoso, Pernambuco, Brazil. G–I, Diploria labyrinthiformis (Linnaeus, 1758); figured specimen = SUI122810 (FA1061), Bocas del Toro, Panama. J–L, Pseudodiploria strigosa (Dana, 1846); figured specimen = SUI122813 (FA1062), Bocas del Toro, Panama. M–O, Pseudodiploria clivosa (Ellis & Solander, 1786); figured specimen = SUI122807 (FA1060), Bocas del Toro, Panama.
