Audouinella Bory, 1823, nom. cons.
Holotype species: Audouinella miniata Bory
Currently accepted name for the type species: Audouinella hermannii (Roth) Duby
Original publication and holotype designation: B[ory de Saint-Vincent, J.B.G.M.] (1823). Céramie Ceramlum.. In: Dictionnaire Classique d'Histoire Naturelle. (Audouin, I. et al. Eds) Vol. 3, pp. 341-342. Paris: Rey et Gravier; Baudouin Frères.
Taxonomic status: currently recognized as a distinct genus.
Most recent taxonomic treatment adopted: Harper, J.T. & Saunders, G.W. (2002). A re-classification of the Acrochaetiales based on molecular and morphological data, and establishment of the Colaconematales, ord. nov.. British Phycological Journal 37: 463-475.
The orthography "Audouinella" has been conserved over the original "Auduinella". Named for the French entomologist Jean Victor Audouin (1797-1841). - (19 Oct 2015) - M.D. Guiry
At one time including virtually all species of Acrochaetiaceae, the genus is circumscribed (Harper & Saunders 2002) now to include only freshwater species. - (5 Oct 2010) - M.D. Guiry
Description: Thallus uniseriate filamentous, heterotrichous or with unicellular base, rarely over 5 mm high. Cells with one to several parietal chloroplasts of various shapes, always without pyrenoids. Sexual life histories, where known, with 2 free phases, in some species the gametophyte with a unicellular base and smaller than the tetrasporophyte, in others (including the type species) the generations isomorphic. Spermatangia in small corymbose clusters. Carpogonia sessile or pedicellate, distinct carpogonial filament absent. Post-fertilization development direct; carposporophytes globose with terminal sporangia; sterile involucre absent. Tetrasporangia single or in clusters, cruciately divided. Monosporangia in many species the only known form of propagation, but also produced by gametophytes and tetrasporophytes of sexual reproductive species. Worldwide, with both marine and freshwater representatives; epilithic, epi-/endophytic or epi-/endozoic. At present a rather heterogenous assembly of species, in need of revision. Emended by J.T. Harper & G.W. Saunders (2002: 471). Now comprises freshwater spp. [Acrochaetium comprises marine spp].

Numbers of names and species: There are 254 species names in the database at present, as well as 15 infraspecific names. Of the species names, 45 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.
