Type species: Flustra coriacea Esper, 1791
Gray proposed the genus Micropora, with Flustra coriacea as the only species. The material he was using was that identified by Johnston (1847), as Flustra coriacea (Esper, 1791). Harmer (1926) argued that Esper's species was actually not published until 1806-1816, and also was a synonym of Cellepora nobilis Esper, 1796 (now Calpensia) and thus was not a valid species. Harmer proposed that the material that Johnston misidentified be accepted as the type species of Micropora, as Flustra coriacea Johnston (not Esper), nevertheless admitting that this was not in strict accordance with the Rules of Zoological Nomenclature.
