DESCRIPTION

Small massive plocoid colony (8 to 30 mm) with well calibrated circular calices separated by a wide porous coenosteum. The free, straight and smooth septa sometimes look like small spines on the inner edge of the calice. During their growth, calices tend to modify their trajectory, giving a wavy aspect to the lumen in longitudinal sections. No columella nor endotheca. Wall porous, synapticulothecal. The budding seems to be extracalicular.

Calicular diameter: 0.4 to 1 mm – Distance between calices centers: 1.5 to 3 mm – Number of septa: 6 to 8.

SIMILARITIES AND DIFFERENCES

Differs from Plagiosolenacis laffittei Alloiteau, 1957 and Paleomillepora liasica Gabilly & Lafuste, 1957 by the presence of welldeveloped septa.Differs also from Etallonasteria Roniewicz,1987 and Alveopora Blainville, 1830 by its smaller and more spaced calices and by the total lack of endothecal structures.In addition, the species under the genus Alveopora generally present a welldeveloped columella and teeth along the inner edges of septa.
