Nomenclatural notes
In ING the type species is cited as H. pinastroides (S.G.Gmelin) Kützing (Fucus pinastroides S.G.Gmelin) and in Phillips & De Clerck (2005: 17) it is cited as H. pinastroides (S.G. Gmel.) Kütz [=H. incurva (Huds.) Batters). Fucus pinastroides S.G.Gmelin is an illegitimate names as the author cites Fucus incurvus Hudson, 1762, in synonymy. - (8 May 2007) - M.D. Guiry

Originally 'Halopithys', the correct othography is Halopitys (De Toni 1903: 1080; Preda 1908-9: 190, and Athanasiadis 2016: 1382, footnote 4); however, alteration of Kützing's original spelling would requries conservation. - (19 Jan 2017) - M.D. Guiry

Description: Thallus erect, attached by a rhizomatose holdfast; monopodial with many polysiphonous cylindrical branches, 5 pericentrals enclosed by several layers of corticating tissue; branches regularly and pectinately arranged in two adaxial rows, often paired, branches dorsiventrally oriented, especially notable in distal branchlets which have recurved apices. Trichoblasts in a single median row on dorsal side of thallus. Reproduction by lanceolate tetrasporangial stichidia formed in positions of ultimate branchlets; tetrasporangia tetrahedrally divided, two per segment forming two longitudinal rows in the stichidia, borne on pericentrals 3 and 4. Gametangia borne in positions of trichoblasts on dorsal sides of specially produced polysiphonous ramuli; spermatangial capitula ovoid, several on each ramulus; cystocarps spheroid to ovoid, usually singly produced on fertile ramuli which become stalks of mature cystocarps.

Numbers of names and species: There are 6 species names in the database at present, of which 3 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..

Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in CD format. These AlgaeBase descriptions are now being continually updated, and each current contributor is identified above. The PSA and AlgaeBase warmly acknowledge the generosity of all past and present contributors and particularly the work of Dr Parker.

Descriptions of chrysophyte genera were subsequently published in J. Kristiansen & H.R. Preisig (eds.). 2001. Encyclopedia of Chrysophyte Genera. Bibliotheca Phycologica 110: 1-260.
