Description: Thalli decumbent to erect, arising from a matted rhizoidal holdfast, up to 20 cm long, with broadly flabellate to irregularly laterally branched fronds. Growth initiated by a complete row of apical cells. Thalli usually 7-12 cells thick with an outermost layer of cortical cells overlying the larger internal medullary cells. Cells in transverse section rectangular, arranged in tiers with 2 cortical cells overlying each medullary cell. Medullary cells of uniform size except for the markedly larger central layer. Cortical cells with numerous discoid chloroplasts. Hairs arranged in concentric lines or scattered tufts. Sporangial sori scattered or in concentric bands on both surfaces of the thallus, indusiate, without paraphyses. Sporangia without a basal stalk cell, producing 8 spores. Oogonia in indefinite sori on both surfaces of the frond. Antheridial plants not known. Tropical to temperate seas.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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