Holotype species: Jaagiella alpicola Vischer
Original publication and holotype designation: Vischer, W. (1960). Reproduktion und systematische Stellung einiger Rinden- und Bodenalgen. Schweiz. Z. Hydrol. 22: 330-349.
Taxonomic status: currently recognized as a distinct genus.
Description: Plants formed of multiseriate filaments, giving rise to globular masses of cells from which grow out branches of sarcinoid packets of cells at base. Branches decrease in width towards summit where uniseriate. Cells uninucleate with parietal chloroplasts, without pyrenoids. Asexual reproduction in culture by means of branches on agar which consist of rounded, thick-walled cells which function as akinetes. Some surface cells globular, producing 2 to 4 aplanospores. Zoospores biflagellate. Sexual reproduction unknown.

Comments: Jaagiella obtained from soil in Europe and description based on plants grown in culture. The poorly known and incompletely described genus Filoprotococcus is undoubtedly synonymous with Jaagiella and its name should have priority.
Numbers of names and species: There is only one species or infraspecific name in the database at present, which has 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
