Description: Thalli erect, arising from a matted rhizoidal holdfast, up to 80 cm long, complanate, divided into sub-dichotomous to sub-palmate segments, 0.5-5 cm broad, with undulate to dentate margins, lacking midrib or veins. Growth initiated from a short row of apical cells. Thallus 2-10 cells thick, with an outermost layer of small cortical cells overlying larger, multilayered medullary cells, not arranged in rows in transverse section. Hair tufts scattered with hairs arising from a depression in thallus. Sporangia scattered across both thallus surfaces, above, partially or entirely embedded in thallus, producing 4 spores. Oogonia scattered singly or in small groups over both surfaces of the thallus. Antheridial sori scattered across both thallus surfaces leaving a sterile margin, above, partially or entirely embedded in the thallus. Widely distributed in tropical and temperate waters of Caribbean Sea South America, New Zealand, Australia, Japan, French Atlantic Coast, Mediterranean Sea and Morocco.

Numbers of names and species: There are 37 species names in the database at present, of which 24 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
