Miscellosmilia Eliášová, 1976 View in CoL
Type species. Miscellosmilia famosa Eliášová, 1976 View in CoL Description Solitary turbinate or cylindrical coral with a circular outline. Septa compact. Microstructure of smallsized trabeculae, septa with a median dark line. Septa in cross section externally slightly thicker, becoming slightly thinner towards the centre. Symmetry of septa radial and regularly hexameral. Cycles of septa subregular. Septal cycles differ in length and thickness. First two or three septal cycles extend to the corallite centre, later cycles are shorter. Septa occasionally connected to each other close to the corallite centre. Septal distal margin unknown, lateral face with numerous thorns, inner margin smooth. Pali absent. Some septa may be attached to the columella. Short costae are present. Synapticulae absent. Columella lamellar. Endotheca consists of numerous thin tabulae. Wall absent. Epitheca present .
Remarks Te genus was thoroughly described by Eliášová (1976).

Description Solitary cylindrical corals with a circular outline. Septa compact. Microstructure not preserved. Septa in cross section externally slightly thicker, becoming slightly thinner towards the centre. Symmetry of septa radial and regularly hexameral. Cycles of septa subregular; there are three complete septal cycles and the beginning of a fourth cycle. Septal cycles differ in length and thickness. Te first two cycles cannot be distinguished; they extend to the corallite centre, the third cycle reaches halfway around the corallite radius. Te septa of the beginning fourth cycle are still shorter than those of the third cycle. Septa not connected to each other. Septal distal margin unknown, lateral face with thorns, inner margin smooth. Pali absent. Some septa of the first or second cycle are attached to the columella. Costae not visible. Synapticulae absent. Columella lamellar. Endotheca consists of thin tabulae. Wall absent. Epitheca present.
Remarks Te genus is monospecific and the present two specimens compare well in corallite dimensions and septal counts to the holotype of Miscellosmilia famosa .
