Nomenclatural notes
Monotypic when first introduced. - (24 Jan 2017) - M.D. Guiry

Description: Thallus prostrate, growing as spreading flattened dorsiventral blades attached by simple or branched multicellular rhizoids with or without multicellular digitate terminal pads. Structure uniaxial or multiaxial, with a horizontally growing mesothallus giving rise to assurgent dorsal and ventral perithallial filaments. Hairs present or absent. Vesicular cells terminating dorsal and, occasionally, ventral perithallial filaments. Where known, spermatangial axes forming in male nemathecia and developing into dense elongate packets following the complete conversion of nemathecial paraphyses. Carpogonial branches and auxiliary cell branches produced in female nemathecia. Auxiliary cell branches 3- or 4- celled. Gonimoblasts developing from diploidised auxiliary cells. Tetrasporangia irregularly cruciate to irregularly zonate, formed in nemathecia devoid of paraphyses.

Numbers of names and species: There are 11 species names in the database at present, of which 6 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
