Holotype species: Chlamydopodium pluricoccum (Korshikov) Ettl & Komárek

Taxonomic status: currently recognized as a distinct genus.

Most recent taxonomic treatment adopted: Tsarenko, P.M. (2011). Chlorococcales. In: Algae of Ukraine: diversity, nomenclature, taxonomy, ecology and geography. Volume 3: Chlorophyta. (Tsarenko, P.M., Wasser, S.P. & Nevo, E. Eds), pp. 232-264. Ruggell: A.R.A. Gantner Verlag K.-G..

Description: Solitary cells sometimes occurring in dense aggregations attached to substratum by mucilaginous basal pad; protoplasts sometimes raised above substratum by mucilaginous base. Cells 15-50 x 6-20 &m, oval to fusiform to egg shaped or slightly irregular and asymmetric, broadly rounded to pointed at upper end. Cell walls smooth, more or less thickened. Cells uninucleate with more or less central nucleus, contractile vacuoles absent; chloroplast single and parietal, band shaped to lobed; pyrenoids one to five, with starch sheath. Asexual reproduction by biflagellate zoospores; sporangial divisions simultaneous or successive. Hemiautospores and thick walled akinetes produced in some species. Zoospores 8-14 x 2.5-8.5 with band-shaped chloroplast, stigma, two apical contractile vacuoles and with or with papillae. Zoospores attach by apical end and withdraw flagella. Heterothallic sexual reproduction described in C. starii by isogametes similar to zoospores . Zygotes round, to 20 &m diameter, with smooth cell walls. Meiosis presumably associated with zygote germination. Chlamydopodium from soil or associated with algae or animals; reported from Europe, North America, Caribbean; most species with highly localized distributions. C. fusiforme, C. bulgariense, C. vacuolatum, and C. starrii available in culture collections (e.g. UTEX) With Characiochloris comprise only genera in Characiochloridaceae. Genus distinguished from Characiochloris by absence of contractile vacuoles in vegetative cells. Included by some authors in Characium; C. vacuolatus assigned to Apodococcus by Hindák (1984). Species distinguished based on differences in cell size and morphology and chloroplast morphology.

Numbers of names and species: There are 8 species names in the database at present, as well as 1 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.

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.
