Description
Corallum ramose with cylindrical or slightly compressed branches, corallites curving gently away from axial longitudinal direction and opening obliquely to surface on small branches, perpendicularly on large branches, calices may show septal ridges. Walls thin in axial region, thickening to become wide stereozones distally, with distinct growth lamellation; corallites polygonal in section but tabularium cylindrical distally because of wall thickening; mural pores common; septal spines may project into lumen; tabulae complete; new corallites originate in one of two positions, either near axis of branch or near boundary between inner thin-walled and outer thick-walled zones; the latter do not produce new corallites. [Many Paleozoic species have been referred to Striatopora but now require revision in light of OLIVER'S precise study of type species (OLIVER, 1966, p. 448).]
