Depressiogeodia Cárdenas, Rapp, Schander & Tendal, 2010: 106 .

This ‘genus’ was erected under the rules of the Phylocode, which does not recognize ranks or type species. The ‘definition’ of Depressiogeodia is quoted from the original paper: ‘(nomen cladi novum): (stem-based) the most inclusive clade containing Geodia barretti Bowerbank, 1858 and not Geodia gibberosa Lamarck, 1815 and Geodia cydonium (Jameson, 1811) ’. The ‘genus’ name is here considered unavailable, even though encompassing at least two named species, Geodia barretti and G. hentscheli Cárdenas et al. 2010 . These species are to be reverted to genus Geodia . Phylocode and Linnean classifications show fundamental differences. The WPD and WoRMS have committed themselves to the latter.
