Type species
A type species for this genus does not appear to have been designated.

Status of name
This name is currently regarded as a synonym of Xiphosiphonia pennata (C.Agardh) Savoie & G.W.Saunders

Type information
Syntype localities: "In mari Mediterraneo. — In mari Atlantica ad Gades." [Mediterranean, Atlantic at Cadíz] (Agardh 1824: 124). Lectotype: LD Herb. Alg. Agardh 39271 (Womersley 2003: 340). Notes: Lectotype selected from Mediterranean?

Origin of species name
Adjective (Latin), pinnate (Stearn 1985).

Synonym(s)
No synonyms are currently included in AlgaeBase.

Nomenclatural notes
Agardh included in synonymy "Conf. mollis, Drap. and Ceram. pennatum, Roth"; there are two binomials with the name Ceramium pennatum attributable to Roth but this citation seemingly refers to Conferva pennatum Roth, 1800, nom. illeg. Conferva mollis Draparnaud, a manuscript name [INA], was included in the synonymy of Ceramium pennatum Roth by Roth (1806: 133). Hutchinsia pennata is thus treated as a new name. Silva, Basson & Moe (1996: 549) write: "Pterosiphonia pennata is traditionally attributed to (Roth) Falkenberg (1901: 263). Ceramium pennatum Roth, the intended basionym, is in fact a purification of C. pennatum (Hudson) Roth (1800b: 171) (Conferva pennata Hudson, 1762: 486; syntype localities: England: between Margate and Dover, Kent; Walney Island, Lancashire). Roth, having decided that he did not have Hudson's C. pennata in hand, redescribed his material without proposing a new name. Consequently, in accordance with Art. 48, C. pennatum Roth 1806 is treated as a new species. Since its name is a later homonym and not priorable, Hutchinsia pennata C. Agardh is treated as a nomen novum in accordance with Art. 58.3. Conferva pennata Hudson is traditionally assigned to the Sphacelariales, but Prud'homme van Reine (1982: 242) rejected it as a name of uncertain application." - (8 Oct 2016) - M.D. Guiry

Savoie & Saunders (2016: 926) note "There appears to be more than one genetic species group currently attributed to P. pennata in Spain. Díaz-Tapia and Bárbara (2013) collected two genetic groups from the Iberian Peninsula in Spain that they identified as P. pennata.... A comprehensive molecular and morphological study is needed for this species complex." In order to resolve this, it will be necessary to establish if the type is in herb. Agardh or in herb. Roth since Hutchinsia pennata C.Agardh is effectively a new name for Ceramium pennatum Roth, nom. illeg. - (8 Oct 2016) - M.D. Guiry
