Taxonomy Phymatolithon tenue has incorrectly been associated with the name Leptophytum leave, a heterotypic synonym of Phymatolithon lenormandii. Complex nomenclatural issues are involved. Düwel & Wegeberg (1996) concluded from a study of relevant type specimens and other material that Phymatolithon tenue was a distinct species, that the designated epitype of Leptophytum laeve Adey (1966) was conspecific with the type of Phymatolithon lenormandii, and that Adey's (1966) concept of Leptophytum laeve was in full accord with Phymatolithon tenue (also see Woelkerling et al. 2002). The holotype of L. leave, a Strömfelt specimen originally described as Lithophyllum laeve (Strömfelt 1886), was considered by Düwel & Wegebrg (1996) to be demonstrably ambiguous and not critically identifiable for purposes of the precise application of a name to a taxon, necessitating designation of an epitype. The interpretation (Athanasiadis 2007: 485) that Phymatolithon tenue is a heterotypic synonym of Leptophytum laeve stems from the arguments (Adey et al. 2001) that the designated epitype and the holotype of L laeve differ taxonomically and that the designated epitype is in serious conflict with the protologue. Based on these arguments, Athanasiadis & Adey (2003) proposed the formal conservation of the name Lithophyllum laeve Strömfelt with a conserved type. The nomenclatural Committee for Algae (Compère 2004), however, concluded that the arguments mentioned above were not substantiated, and the proposal was unanimously rejected. The Committee for Algae (Prud'homme van Reine 2011) also noted that subsequent arguments (Athanasiadis & Adey 2006: 72; Athanasiadis 2007: 485) that the epitypification of Düwel & Wegeberg was "non-effective" involve incorrect, unacceptable interpretations of the International Code of Nomenclature.
