Corallum light, caespitose, 27 x 19 cm across, 10-11 cm high; a confused but not very crowded mass of branches and branchlets. Branches arise from narrow, short base, only 1.5 cm across; lax, very proliferous, distantly coalescent, slightly attenuate, cylindrical; one branch 14.5 cm long, 6.5 mm across at base, 4.5 mm about a cm below apex; more than half of length towards base covered with distant subimmersed corallites and occasional projecting or verruciform ones; remaining distal region bears prominent corallites mixed with low ones, just as on terminal branchlets. Lower surface of peripheral, almost horizontal branches has more dispersed, mostly verruciform corallites. Branchlets spiciform, 2-2.5 cm long, 3-4 mm diameter, usually almost at right angle to branch, projecting in all direction so that corallum has tangled appearance.
Axial corallite cylindrical, around 2-2.5 mm diameter, distinctly exsert; wall about half calinical diameter in thickness, porous, costate, rim not rounded. Septa in 2 complete cycles. Primaries short of radius midpoints, directives only slightly distinguishable. Secondaries slightly narrower than primaries.
Radial corallites rather distant on distal portion gradually decreasing in height towards apexl; prominent ones nariform, projecting 1.5 mm, up to 1.5 mm across, rim horizontal so oval calice faces upward; few taller tubular ones bearing buds found here and there. Wall thin, delicate, lacelike, very porous; costate, some older corallites may have few spines. Mixed with tall corallites are low ones, also nariform, becoming flush or subimmersed towards base where they are most abundant. Septa irregularly developed; directives always prominent, confluent at base of fossa of tall radials; other septa (including occasional secondaries) very narrow, represented by rows of spines.
Intercalicinal areas rough; reticulum irregular with ridges bearing distant, foliate or slender spinules; meshes diffused. On younger portion, threads prominent, continuous calicular wall as costae.
