Corallum explanate, foliate, plicate (specimen with attachment broken off); edge c. 3 mm thick, serrate, each tooth the free end of a ridge; broken inner edge c. 10 mm thick.
Lower surface non-epithecate, very fine-grained, with few low conical elevations; few widely scattered corallites indistinguishable without lens. Entire surface looks like an uninterrupted close reticulum with evenly disposed fine spinules, the few calices distinguishable only under the microscope by their 6 septa not very different from threads of reticulum.
Upper surface marked all over with ridges extending up to edge of corallum, wider (3-4 mm) toward central region, narrower (2-2.5 mm) close to periphery; width variable; mostly cut across by shallow depressions into elevated segments or rounded mounds but courses of ridges generally not completely interrupted; summits of ridges well rounded out. Intervening valleys narrow (much narrower than adjoining ridges), containing series of corallites recognizable as tiny pits.
Corallites on upper surface found exclusively within valleys, unequally distant, set in tiny depressions c. 0.8 mm across. Septa not uniform, some calices have 6 primaries equally thin and reaching radius midpoints or beyond, others have 2 or more primaries shorter and thinner, some have 1 or 2 tiny secondaries, most do not have any. All have very wide loculi because of thinness of septa; loculi continue into perithecal reticulum because of absence of circumcalicinal ring.
Peritheca wide; reticulum uniform all over on ridges and in valleys, coarser on upper surface than on lower surface; spines apparently trimmed to even heights, tips truncate.
