Diagnosis Test of porcelaneous high magnesium calcite, of fine randomly oriented rodlike crystals, 1.5 µm to 2.0 µm in length and 0.24 µmin diameter, seen only with the electron microscope, the random crystal orientation refracting light in all directions to result in the milky opacity or porcelaneous appearance in reflected light, wall appears brown and glassy in transmitted light, may have surface layer of variously arranged tabular rhombohedral crystals, commonly with organic lining and may have added adventitious material; true pores may occur in protoconch of some, generally imperforate in post embryonic stage, but may have pseudopores; may have flexostyle or spiral passage between proloculus and later chambers; sexual reproduction in some known to involve many inequally biflagellate gametes with characteristically long blepharoplast and axostyle that are freed in the water column. Carboniferous to Holocene. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]
