Nomenclatural notes
Huisman (2018: 607) notes: "...from the Greek halo (the sea) and plegma (weaved), in reference to the habitat and structure of the alga." - (10 Oct 2018) - M.D. Guiry

Description: Thallus erect or decumbent, with flattened felt-like spongy branched blades; structure with a layered network formed by parallel ecorticate filaments, the cells of which each bear lateral determinate branchlets that anastomose to form a net. Outer surface with short perpendicular or elongate and curved filaments bearing reproductive structures. Cells multinucleate. Spermatangia in subcylindrical heads. Carpogonial branches borne on short branches on cells of surface clusters. Carposporophytes globose, with several successively developing gonimolobes composed entirely of carposporangia, involucrate. Tetrasporangia terminal, tetrahedrally divided, occasionally forming octosporangia.

Numbers of names and species: There are 7 species names in the database at present, as well as 4 infraspecific names. Of the species names, 5 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.

Contributors
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
