Monticulipora sp. in longitudinal (left) and tangential (right) sections. Field of view is 1.0 mm. SMH collection.
Monticulipora can have a wide range of colony morphologies, including encrusting, hemispherical, massive, frondose, and ramose. Monticules are typically present and are conical to elongated, and they typically have clusters of styles and mesozooids. Zooecia contain both diaphragms and cystiphragms, with cystiphragms in both endozone and exozone. Cystiphragms are typically radially arranged around monticules, on the sides of zooecia closest to monticules, rather than on the far side of the monticule as in Prasopora (this is most easily seen in tangential section). Styles are generally short and limited to thick-walled regions, but may be rare or absent in some species. Mesozooids may be common to absent.
