Description
Zoarium encrusting or massive, rarely ramose. Monticules elevated or flush, central cluster of vesicles and ring of larger zooecia with lunaria pardy to altogether radially arranged, on side of zooecia nearest monticular center. Autozooecia long, tubular, with closely spaced planar or curved diaphragms; parrially to completely isolated by vesicular tissue; micro- structure granular or granular-prismatic. Lunaria through endozone and exozone, granular or gran- ular-prismatic; radius of curvature shorter than that of autozooecial wall. Vesicles moderately large, angular; thin granular or granular-pris- matic walls and roofs; rarely boxlike, commonly polygonal or subquadrate blisters. Local zone of thicker vesicle roofs at zoarial surface. (Many species in this large genus are in need of restudy. Early species tend to have larger, more boxlike vesicles, whereas many late Paleozoic species have smaller, polygonal or cystlike vesicles. Cucumulites tuberculatus GURLEY, 1884 is the type species of Cucumulites GURLEY, 1884, by original designation. The holotype is silicified and has not been sectioned, Its apparent syn- onym, C. triearinatus GURLEY, 1884, though mostly silicified and poorly known, has features that are most similar to those of Fistulipora, and Cueumulites is tentatively placed in synonymy with Fistulipora.}
