Spongia agaricina subsp. corlosia (sic) var. fusca Hyatt, 1877

Spongia agaricina subsp. corlosia var. fusca Hyatt, 1877: 524 , pl. 15 fig. 11, pl. 16 fig. 31.

Euspongia officinalis var. rotunda ; Von Lendenfeld 1889: 269.

Spongia (Spongia) fuscoides Van Soest & Hooper, 2020 (in Van Soest et al. 2020: 31, case 46)

Hyatt’s name is not an available name (as it has a fourth name, ICZN art. 45.5). Apart from Von Lendenfeld’s assignment of this to Euspongia officinalis var. rotunda ( Hyatt, 1877 as Spongia officinalis subsp. tubulifera var. rotunda , cf. below), Van Soest et al. 2020 erroneously erected a new name ( Spongia fuscoides , cf.below)for this taxon as a junior homonym of Spongia communis fusca Lamarck, 1814 . Because Hyatt’s name is not available it cannot come into homonymy with an available name (ICZN art. 54.1). Hyatt was apparently unaware that Duchassaing & Michelotti corrected the name corlosia to coelosia in the Errata at the end of their book (p. 122). Thus, in accordance with ICZN art. 32.5.1.1 the name must be spelled coelosia . The WPD lists Spongia (Spongia) coelosia as ‘accepted’ but it is incertae sedis (see below). I propose to assign Hyatt’s material from Florida provisionally, but in accordance with Von Lendenfeld’s suggestion, to Spongia (Spongia) tubulifera Lamarck, 1814 until it has been re-examined (see also below Spongia (Spongia) fuscoides Van Soest & Hooper, 2020 ).
