Raphidocelis Hindák, 1977

Holotype species: Raphidocelis sigmoidea Hindák

Original publication and holotype designation: Hindák, F. (1977). Studies on the chlorococcal algae (Chlorophyceae). I. Biologicke Práce 23: 1-192.

Description: Thalli unicellular or forming small colonies embedded in a highly irregular and structureless mucilage. Cells lunate to sigmoidal, pointed at both ends with evenly granulated cell walls. Cells lengths highly variable and species specific, in the type species 4-10 µm, in the other species 6-25 (-42) µm, mostly 1.5-3 µm wide. Cells uninucleate; chloroplast parietal and single, pyrenoids absent. Asexual reproduction by autospores, 2-4-8 per mother cell; released by cell wall rupture. Autospores and young cells often without granulations. Flagellated stages and sexual reproduction unknown.

Taxonomic status: This name is of an entity that is currently accepted taxonomically.

Most recent taxonomic treatment adopted: Tsarenko, P.M. (2011). Sphaeropleales. In: Algae of Ukraine: diversity, nomenclature, taxonomy, ecology and geography. Volume 3: Chlorophyta. (Tsarenko, P.M., Wasser, S.P. & Nevo, E. Eds), pp. 280-355. Ruggell: A.R.A. Gantner Verlag K.-G..

Comments: Raphidocelis species are planktonic in freshwater, and known only from central Europe. Taxonomic concepts in the monographs differ with overlapping concepts for Raphidocelis, Siderocelis, and Kirchneriella. The three species are distinguished based on cell size and cell shape.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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