Corallum consisting of heavy, creeping, extensive base with stout, usually arcuate branches produced at edges. Base 2.8 cm to 4.4 cm thick, both surfaces irregular, nodulous.
Branches stout, tapering – one branch 4.4 cm high, 2.2 cm across base; another 5.2 cm high, 2 cm diameter at base. Corallites crowded, prominent on upper surface of base and branches; distant, even or subimmersed on lower surface.
Axial corallites 3 mm across, very slightly exsert; wall moderately thick, very porous. Radial corallites on upper surface of various heights and diameters, crowed, mixed together. Height ranging from even with surface but for a low ring circumscribing calice to 3-3.5 mm, the latter just below apex of branches where they are tallest. Diameter ranges from 0.6 for lowest corallites to slightly over 1 mm across mouth of tallest one. Prominent corallites perpendicular to surface, tall ones towards apex slightly appressed but appear vertical being reflexed; spout-shaped, dimidiate; distal wall slightly above general surface, lower wall very high, thin or slightly thickened at edge; distinctly costate, very porous. Lower lip of smaller radials ligulate or acuminate oriented in any direction. Corallites on lower surface distant, subimmersed or plush with surface so this side appears smooth; some corallites obsolescent.
Primaries of axial corallites broad plates extending almost to center of calice, edge smooth or finely dentate; secondaries very narrow, often not complete cycle. In radial corallites, septa underdeveloped, often only one or both directives recognizable while others represented by few scattered spines; completely absent in small radials.
Intercalicinal areas distinctly reticulate, laxly echinulate; echinules low, unevenly disposed. Lower side looks denser, reticulum close, echinules even in disposition and height.
