Dimensions. d (series, min.)= 3–11 mm; d (series, max.)= 13–35 mm; s/mm=18–30/10.

Description. Phacelo-flabellate colony with corallites arranged in short series of up to 6 calices; monocentric corallites compressed; septa straight, S1–S3 nearly equal in thickness, often regularly alternate in length; according to their length 4 septal orders can be distinguished.

Remarks. In the type material of E. karstica from the Montian of Slovenia, the wall seems to be parathecal and the number of endothecal dissepiments appear to be much more numerous than in E. calyculata . However, in several places the presence of a septothecal wall can be seen in E. carstica (see Plate 21, Fig. 2b, upper margin of central corallite series). In addition, in the upper surface view of the colony of E. calyculata the presence of numerous vesicular dissepiments, which correspond to the endothecal development in E. carstica , can be seen (Plate 21, Fig. 5a, e.g., lower right corallite and corallite on the left). Therefore, their synonmy is suggested.

Type locality of species. Oligocene of Italy (Monte Grumi) .

Distribution. Upper Danian of Pakistan, Montian of Slovenia, Middle-Upper Eocene of Spain (Catalonia), Oligocene of Italy.
