Genus Phyllastraea de Fromentel, 1879

TYPE SPECIES. — Phyllastraea hippuritorum de Fromentel, 1879 (by monotypy).

REMARKS

The type of the type species is available (MNHN.F. M03765 ) but without thin sections. Thin sections found in the MNHN labelled as Phyllastraea hippuritorum , but without number, are poorly preserved and do not correspond to the type of the species. Phyllastraea is a plocoid colony with elliptical calices and compact and poorly ornamented septa with T-shaped inner margins. The costae are non-confluent. The wall is septothecal. The columella is lamellar. Ficariastraea Alloiteau, 1952 is an objective synonym. Baron-Szabo (2003) included Phyllastraea hippuritorum in the synonymy of Agathelia asperella Reuss, 1854 . Both species differ in many features (ornamentation of septa, presence of a columella, thickness and formation of the wall) and are not identical.
