Genus FISTULIPORA M’Coy, 1849

Type species. Fistulipora minor M’Coy, 1849 , by original designation. Mississippian (Lower Carboniferous) ; England.

Diagnosis. Massive, encrusting, or ramose colonies. Cylindrical autozooecia with thin walls and complete diaphragms. Apertures rounded, possessing horseshoe-shaped lunaria. Autozooecia separated by the extrazooidal vesicular skeleton.

Remarks. Fistulipora M’Coy, 1849 differs from Eridopora Ulrich, 1882 in having rounded, horseshoe-shaped lunaria instead of triangular ones. Furthermore, Eridopora develops persistently encrusting colonies, whereas Fistulipora may also develop massive and ramose colonies. Fistulipora differs from Dybowskiella Waagen and Wentzel, 1886 , in the shape of lunaria, whose ends do not inflect autozooecial chambers.

Occurrence. Ordovician to Permian; worldwide.
