Description
Corallum ramose, small, corallites cylindrical but closely attached, in places becoming prismatic, walls a thin stereozone, without mural pores or connecting processes, septa thin, sometimes discontinuous laminae, tabulae horizontal; increase calicular, up to five offsets initially within wall of parent. {See STASINSKA, 1967, p. 101. The possibility that this genus is of the subclass Tabulata (?Auloporina), as suggested by STASINSKA (1967, p. 101), must not be overlooked; study of calice is required to establish trabecular nature of septa and whether minor septa are present; epithecal furrows should be studied to establish manner of septal insertion.]
