Colonial, massive, thamnasterioid. Budding extracalicular. Septa compact with occasionally perforated axial ends, laterally granulate and carinate. Columella well-developed, spongy-papillose. Synapticulae present. Endothecal dissepiments thin, subtabulate. Wall synapticulothecal, generally incomplete.


Fungiid forms are generally characterized by fairly porous and coarsely granulated septa. Despite its commonly fungiid appearance, the genus Astraeofungia Alloiteau is characterized by compact septa (with occasionally perforated axial ends) and rather delicate septal ornamentations (Baron-Szabo, 2002 and 2014). Specimens having perforated septa and rather coarse septal ornamentations have been erroneously placed in the genus (see Schöllhorn, 1998, p. 94). Recently, the genus Astraeofungia has been described as having "no wall" (Baron-Szabo, 2014, p. 63), which represents a typing error. The wall of this genus is a synapticulotheca, complete or, more often, incomplete.
