Most recent taxonomic treatment adopted: Saunders, G.W., Huisman, J.M., Vergés, A., Kraft, G.T. & Le Gall, L. (2017).

Description: Erect, flat, subdichotomously to polychotomously branched in one plane to several orders, often with numerous bladelets from margin. Firm when fresh, becoming cartilaginous. Stipe short. Holdfast small, discoid. Medulla of large isodiametric to slightly elongate, thick-walled cells arranged in a single layer, surrounded by slender, small-celled filaments, which also form the cortex. Stellate cells absent. Cuticle present. Carpogonial branch 3-celled, borne singly on an elongate, often lobed supporting cell with several elongate, irregularly clavate subsidiary cells. Fusion cell lobed, producing several connecting filaments that contact a remote auxiliary cell, also bearing isodiametric to slightly elongate subsidiary cells. Carposporangia surrounded by gonimoblast and pericarp filaments. Cystocarp protruding slightly. Carpostome lacking. Spermatangia superficial. Tetrasporophyte isomorphic. Tetrasporangia cruciate, scattered in cortex.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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