Dimensions. c-c= 5–10 mm; s=36–60, in late budding stages the number of septa may be larger; s/mm=6–7/2; size of the colony= 7 cm in diameter.

Description. The massive and thamnasterioid colony has slightly protuberant calices, which appear to be subplocoid. Increase in corallites is due to intracalicinal gemmation. Costosepta are subcompact or porous, confluent or subconfluent, nearly equal in thickness, and have pennulae and spiniform or coarse, rounded granules laterally. Their inner ends have the tendency to fuse. About 20 septa reach the centre of the calice. The columella is spongy-papillose, well-developed. Paliform structures can be frequently observed. Synapticulae are irregularly disposed. There is no wall between the corallites. Endotheca is formed by numerous vesicular or subtabulate dissepiments. Septal microstructure is made of thick monaxial and polyaxial trabeculae.

Type locality of species. Upper Santonian of Austria (Gosau Group) .

Distribution.?Senonian of Georgia (in Caucasia), Santonian-Campanian of Austria (Gosau Group), Upper Campanian of Bulgaria, Middle-Upper Maastrichtian of the UAE / Oman region,?Danian of France (Vigny).
