DESCRIPTION

Solitary, discoid to fungiform corallum (the diameter exceed the height of the corallum) showing a circular adhesion scar on its lower face. Radial elements are subcompact, straight, free costosepta with stylophyllid septal structure that produce periodical fluctuations in width of septa in transverse section and sometimes project in the axial space at the inner edge. Endotheca made of rare peripheral dissepiments. No synapticulae observed. A concentrically wrinkled epitheca s.l. covers the external part of the corallum.

Calicular diameter: 20 to 33 mm – Number of septa: 60 to 70 – Septal density: 4 to 5 per 5 mm.

SIMILARITIES AND DIFFERENCES

This species differs from the other Triassic and Liassic ones of the genus by its ratio between number of septa and diameter and/or by its very specific shape, wider than high.
