Original publication and holotype designation: Iyengar, M.O.P. (1932). Fritschiella, a new terrestrial member of the Chaetophoraceae. New Phytologist 31(5): 329-335.
Taxonomic status: currently recognized as a distinct genus.
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 filamentous and heterotrichous, consisting of colourless, rhizoidal filaments penetrating soil surface. Prostrate system of crowded, irregularly rounded, clusters of small cells with dense contents, and erect system of irregularly branched filaments of short cells below, more elongated cells above, and terminating in conical cells. Both cell types uninucleate, with parietal chloroplast and several pyrenoids. Reproduction confined to cells of prostate system. Zoospores of 3 types quadriflagellate macro- and microzoospores, and biflagellate microzoospores. Sexual reproduction isogamous and gametes biflagellate. Fritschiella terrestrial, more or less gregarious on moist soil or silt including drying rain-water puddles; also reported from hair of sloths. Widely distributed in tropical and subtropical parts of North Africa and Asia. Ultrastructural investigations reveal plasmodesmata, a phycoplast, and membranes closely appressed to pyrenoids. Detailed information exists on the fine structure (e.g. cytoskeleton) of naked zoospores.

Numbers of names and species: There are 2 species names in the database at present, of which 2 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.
