Nomenclatural notes
Silva, Meñez & More (1987: 96) comment that the “...name Chaetomorpha tortuosa (Dillwyn) Kützing, although often cited, is non-existent. In fact, Kützing (1845: 205) transferred Chaetomorpha tortuosa Dillwyn (1805: pl. 46) to Rhizoclonium and established a new species, R. capillare to accommodate Mediterranean populations that other workers had associated erroneously (in his opinion) with Dillwyn’s plant. Still later, Kützing (1849: 376) transferred R. capillare to Chaetomorpha, unfortunately changing the epithet to tortuosa and thus setting the stage for serious confusion. Two taxonomic synonyms listed by Ardissone (1887: 209) have equal priority, Conferva liguistica Kützing (1843: 259) and Spongopsis mediterranea , of which the former is herewith chosen to serve as the basionym of the correct name for the species.”
