Description

provided by World Register of Marine Species
Lamellar, dome-shaped, hummocky or ramose thamnasterioid corallum. Variation from isotropic to stretched thamnasterioid. Epitheca present. Intracalicular increase. Radial elements are compact biseptal sheets, anastomosed, often sinuous and subequal. Distal edge with regular small teeth, lateral faces covered of small horizontally flattened dentate expansions never turned upward and not alternating from a septum to the neighboring one. Acute granules also present. Granules with a tendancy to be aligned in two perpendicular directions on the lateral faces. Inner edge attenuated or rhopaloid often attached to the columella with a trabecular lobe for the longer septa. Microstructure made of simple to compound trabeculae. In transverse section of thick septa, the trabecular axes are not strictly aligned. Hexameral symmetry generally not deciphered, bilateral symmetry generally marked by the anastomosing pattern. Endotheca made of dissepiments close of the distal edge, a little deeper around the styliform columella. Synapticulae or adtrabecular bars present, especially in the peripheral region of corallites, wall absent.
