Molinari-Novoa, Eduardo A., 2021, Nomenclatural notes on algae. III. Further replacement names for various algal taxa, Notulae Algarum 179, pp. 1-7 : 2-3

Genicularina Molinari & Guiry , nom. nov.

Replaced name: Genicularia De Bary, Untersuchungen über die Familie der Conjugaten (Zygnemeen und Desmidieen): 77, 1858 (Charophyta, Gonatozygaceae ), nom. illeg., non Genicularia Roussel (1806: 84) , Wrangeliaceae .

Type: Gonatozygon spirotaenia De Bary (monotypic genus at the time of publication).

Notes: Roussel (1806) created many names for algae without making the appropriate combinations for them, including Genicularia . He cited the type as “ Conferva geniculata L.” nom. inval., one of the names included in the synonymy of Conferva corallina Linnaeus (in Murray 1774), itself an illegitimate replacement name for Conferva corallinioides Linnaeus , the basionym of Griffithsia corallinioides (Linnaeus) Trevisan , the current name for the type species of Griffithsia C.Agardh , nom. cons. We follow Guiry (2013) for the taxonomy of the newly named genus.
