Chlamydopodium Ettl & Komárek, 1982

Holotype species: Chlamydopodium pluricoccum (Korshikov) Ettl & Komárek

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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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