Type Species
The type species (lectotype) of the genus Hypnea is Hypnea musciformis (Wulfen) J.V.Lamouroux.

Status of Name
This name is of an entity that is currently accepted taxonomically.

Basionym
Fucus valentiae Turner

Type Information
Type locality: Red Sea; (Dawson 1961: 239) Type: Lord Valentia; BM (ex K); (Lipkin & Silva 2002: 23)

General Environment
This is a marine species.

Description
Yamagishi & Masuda (1997: 140, 141) note that among plants growing in Japan, no clear-cut differences between H. charoides and H. valentiae are found and that the specimen of H. valentiae shown by Dawson (1954: 436, fig. 47) is similar to the typical form of H. charoides found in Japan. They treat these as a H. charoides-valentiae complex.

Habitat
Occurs in sheltered localities but usually where there is current flow, e.g. on the sides of channels (Womersley 1994: 445).

Taxonomic note
John et al. (2004) cite Hypnea cornuta (J.V. Lamour.) J. Agardh as a synonym of this species. - (11 May 2006) - G.M. Guiry

Distributional notes
According to Tsiamis & Verlaque (2011), world distributions should be considered with caution due to numerous confusions and misidentifications (Verlaque et al., in press). Silva et al. (1996) note that this may be a misapplied name (fide Womersley, 1994: 445). Womersley (1994: 445) notes that the southern Australian specimens agree fairly well with Turner's original illustration and description [of Fucus valentiae] , and he refers them to this species pending further study of the type specimens and variation of the taxa of Hypnea. This species has been introduced into the Mediterranean (Verlaque et al. 2015: 115), probably via oyster, being first found at Etang de Thau, France, in 1996. - (01 November 2012) - G.M. Guiry
See note on descriptions. Chiang, Y.M (1997: 167, 169) refers to the Hypnea charoides-valentiae complex and notes that many intermediate forms are found in Taiwanese waters. Lewmanomont (1997: 187) also refers to the above complex and notes that "this species is rather common in the Gulf of Thailand". - (11 May 2006) - G.M. Guiry

Habitat notes
[Greece]. In mid-littoral zone, epilithic in sheltered rock pool on a semi-exposed rocky shore; associated flora include Dictyota implexa and Ulva rigida; alien macroalgae Caulerpa racemosa var. cylindracea, Lophocladia lallemandii and Stypopodium schimperi found nearby (Tsiamis & Verlaque 2011). - (01 November 2012) - G.M. Guiry
Widespread in warm seas; on rock flat, ca. 1 m below low water; on rock flat gently sloping seawards, ca. 30 cm below low water (Lipkin & Silva 2002). Tropical and subtropical waters; occurs in sheltered localities but usually where there is current flow, e.g. on the sides of channels; 0-11 m deep; on rock and on marina (Womersley 1994). - (03 June 2010) - G.M. Guiry

Usage note
Nematicidal activity (Abid et al. 2005). - (22 May 2007) - G.M. Guiry
