Nomenclatural notes
Both the name and the type has been conserved. - (26 Jan 2017) - M.D. Guiry

Description: Thallus dorsiventral, with prostrate and erect indeterminate axes bearing simple or branched determinate laterals usually at regular intervals; apices occasionally straight, but usually curved to circinate. Attachment by rhizoidal haptera terminal on special branches ('cladohaptera') or clustered on peripheral cells ('peripherohaptera'). Axes with 4–9 pericentral cells, each dividing transversely into 2 tiers, corticate or not. Branching exogenous, rarely endogenous. Trichoblasts absent. Spermatangia superficial on corticated polysiphonous determinate laterals with or without a sterile tip. Procarps 1–4 per segment on polysiphonous determinate branches, each procarp with a single sterile group and a (3–) 4- celled carpogonial branch. Carposporophyte with a short branched gonimoblast bearing clavate terminal carposporangia. Cystocarps subterminal, ovoid to subspherical; pericarp with 6–14 longitudinal filaments, corticated. Tetrasporangia tetrahedrally divided, whorled, borne in stichidia on determinate laterals, up to 25 segments long; fertile segments with 4 or 5 pericentral cells and tetrasporangia, each protected by 2 or 3 cover cells that are often subdivided [after Womersley (2003: 362)].

Numbers of names and species: There are 87 species names in the database at present, as well as 55 infraspecific names. Of the species names, 40 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
