Two pieces with the same number, one of them has a polished surface. The non polished syntype shows another corallite with a lamellar columella but not a cardinal septum. It should be discarded.
(From the syntype) Probably phaceloid corallum (the polished syntype shows on one side a single corallite and on the other face, in correspondence, a set of three corallites not yet separated) Epitheca ?, no costae. Radial elements are compact, free, attenuated, smooth, straight, curved or sinuous, unequal. A cardinal septum thicker and longer than others. Inner edge attenuated or slightly clavate, lateral faces smooth, no pali. Microstructure unknown. Hexameral symmetry absent, bilateral symmetry strongly marked by the cardinal septum. Endotheca not observed , columella absent (but a columellar septum), synapticulae absent, wall peripheral and thick (sparitized on the syntype)
