Diagnosis Test attached, up to 27 mm in height, early stage planispirally coiled, later chambers spiralling upward to form a large cylindrical upright and terminally branching structure, large chambers on the branches communicating by open passages, central core formed by irregular vertical tubes that spiral up the trunk and branches, to open distally on the branches; wall calcareous, hyaline, with irregularly scattered coarse perforations that result from outward fusion of the finer pores at the inner wall surface, inner septal walls imperforate, surface lacking both the areolae of Homotrema and the pillar-pores of Miniacina; early upright spiralling chambers with terminal aperture that remains as a foramen connecting successive chambers, an additional opening leads into the axial network of stolons that in turn open to the exterior at the ends of the branches. Eocene to Holocene; cosmopolitan in warmer waters. (Loeblich & Tappan, 1987, Foraminiferal Genera and Their Classification) [details]Grammatical gender ICZN 30.1.2. a genus-group name that is or ends in a Greek word transliterated into Latin without other changes takes the gender given for that word in standard Greek dictionaries;
The suffix -trema comes from the Greek τρῆμᾰ (neuter): hole, aperture, perforation.
Hickson (1911, p. 452) indicates: "Of the genus Sporadotrema I recognise two species, S. cylindricum (Carter) which is fully dealt with in this paper and S. mesentericum (Carter)." Hickson clearly considers his genus to be neuter. [details]
