Original publication and holotype designation: Braun, A. (1850 '1851'). Betrachtungen über die Erscheinung der Verjüngung in der Natur. pp. [i]-xvi, -363, pls I-III. Leipzig: Verlag von Wilhelm Engelmann.
Taxonomic status: currently recognized as a distinct genus.
Gender: This genus name is currently treated as neuter.
Most recent taxonomic treatment adopted: Burova, O.V., Tsarenko, P.M., Kovalenko, O.V., Petlovany, O.A., Mikhailyuk, T.I. & Lilitska, G.G. (2011). Chaetophorales. In: Algae of Ukraine: diversity, nomenclature, taxonomy, ecology and geography. Volume 3: Chlorophyta. (Tsarenko, P.M., Wasser, S.P. & Nevo, E. Eds), pp. 264-278. Ruggell: A.R.A. Gantner Verlag K.-G.
Description: Plants consisting of uniseriate, simple or irregularly branched, prostrate filaments. Cells globose or cylindrical, uninucleate, each with single parietal chloroplast and one to several pyrenoids. Setae arise on upper surface of filaments, one or several per cell, unicellular, long, often swollen at base. Asexual reproduction by quadriflagellate zoospores or aplanospores. Sexual reproduction oogamous, large oosphere with stalk and quadriflagellate male gametes. Zygote thick-walled, containing reddish to yellowish oil droplets. Aphanochaete cosmopolitan; frequent epiphyte in hard and eutrophic water (sometimes brackish water). Especially common on aquatic spermatophytes and filamentous green algae including Cladophora and Oedogonium. Principal characters used to distinguish species associated with germling development, length of primary filament, size and form of mature thallus, and shape of setae. Only 4 species considered valid with 2 others doubtful. Ultrastructural studies of two species, A. elegans and A. magna, revealed plasmodesmata and pyrenoids transversed by membranes. Phycoplast ontogeny and other features of cytoskeleton also investigated.

Numbers of names and species: There are 17 species names in the database at present, as well as 8 infraspecific names. Of the species names, 7 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.
