Colony irregularly pulvinate, 15 cm longest diameter, about a third of which carries many dead corallites and a few others whose living portion occupies only upper cm or so; bigger portion of colony bear olive corallites standing 2.5-4 cm above surface.
Corallites slightly sinuous, mostly turbinate, 0.5-1 cm apart. Turbinate corallite 2.5 cm high, 0.5 cm across at base, 0.8 cm across just below calicinal rim; one not turbinateand without bud 3.5 cm high, 0.6-1 cm across at base, 0.5-1 cm across just below calicinal wall. Many corallites produce as many as 5 to 7 lateral buds on their upper region.
Calices oval, elliptical, or very compressed, the latter common among older corallites so that fossa reduced into very narrow slit. A compressed calice measures 2 x 12 mm. A few calices appear to be split by constriction across their middle.
Septa up to 48; principal ones conspicuously thickened especially toward calicinal wall; others thin. Septal edges entire; septal surface very finely, very sparingly granulate. All septa exsert but only at most 1-2 mm over wall; thin septa only slightly exsert.
Costae conspicuous just below calicinal rim, lower downward, finally lost on lower half of calicular column; edges very finely denticulate.
Columella absent. Peritheca covered with numerous small, closed vesicles.
The species differs strikingly from others in the genus by the production of lateral buds and the taller corallites mostly with much compressed calices.
