Taxonomic notes
John et al. (2004) cite Hypnea cornuta (J.V. Lamour.) J. Agardh as a synonym of this species.

Distributional notes
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".

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. - (1 Nov 2012) - Wendy Guiry

Habitat notes
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). - (3 Jun 2010) - Wendy Guiry

[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). - (1 Nov 2012) - Wendy Guiry

Usage notes
Nematicidal activity (Abid et al. 2005). - (22 May 2007) - Wendy Guiry

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).
