Diagnosis Test free, discoidal, large, up to 1 cm in diameter, microspheric test with early planispiral coil, rapidly becoming peneropliform, reniform, and finally with cyclic chambers, macrospheric test with protoconch and deuteroconch followed by cyclic chambers, up to fifty cyclic chambers in the adult, test up to 0.3 mm in thickness near the periphery, sutures slightly depressed, periphery broadly rounded; wall microgranular, calcareous, agglutinated, with imperforate epidermis, no exoskeletal partitions, and chamber interior undivided in early stage, later cyclic chambers with one or more endoskeletal pillars arising from a median position at the floor to extend radially from one septum to the next, pillars may bifurcate and fuse to give an irregular appearance in section (this chamber subdivision gives a superficial but erroneous appearance in section of two layers of chambers, and was so described originally; the anastomosing pillars also have been described as an undulating median partition); aperture multiple, with round openings on the peripheral surface. U. Cretaceous (Cenomanian to U. Santonian); France. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
