| Foliage is spindly and very upright, often being a darker green than normal and slightly rugose. |
| It is not known whether rugose corals had symbiotic photosymbiotic zooxanthellae as modern corals do. |
| The leaf texture is quilted, or rugose, because the veins are depressed below the surface. |
| Grain is orbicular to ovate, concavo-convex, red-brown, and transversely rugose. |
| Domal stromatoporoids are present, as are solitary and colonial rugose corals. |
| With their thicker shells and distinctive internal septae, small solitary rugose corals are easier to see. |
