Original publication and holotype designation: Komárková-Legnerová, J. (1991). Epigloeosphaera, a new cyanophyte genus from Nordic lakes. Arch. Hydrobiol./Algolog. Stud. 62: 7-12.

Description: Unicellular - colonial; colonies microscopic, slightly irregular mucilaginous spheres, on the surface of which are a few irregularly distributed elongated cells; gelatinous spheres usually composed of irregular aggregations. Mucilage homogeneous, not structured, colorless, limited with more or less firm margins. Cells oval or rodlike, more or less distant from one another, without aerotopes, pale blue-green or greyish. Division of cells perpendicular to their longer axis; daughter cells separate soon one from another. Reproduction by the dissociation of colonies in mucilaginous clusters with several or solitary cells. Known from plankton, tychoplankton and epipelon of mesotrophic lakes of Scandinavia (Sweden, Finland), northwest Russia (Karelia, vicinity of St. Petersburg) and central Canada.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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