Chlorogloeopsis A.K.Mitra & D.C.Pandey, 1967

Holotype species: Chlorogloeopsis fritschii (A.K.Mitra) A.K.Mitra & D.C.Pandey

Original publication and holotype designation: Mitra, A.K. & Pandey, D.C. (1967). On a new genus of the blue-green alga Chlorogloeopsis with remarks on the production of heterocysts in the alga. Phykos 5: 106-114.

Description: Thallose; thallus forms a compact stratum of indefinite size, composed of irregular or irregular-rounded cell-packets and aggregates, or of uniseriate to multiseriate short rows of cells (trichomes with 3-20 cells), usually without distinct mucilaginous envelopes, but sometimes single cell-packets enclosed in thin, firm sheaths. Elongated branches or typical filaments not formed. Cells rounded or angular, with pale blue-green, granular content. Heterocytes terminal and intercalary, irregularly disposed, sometimes lacking. Akinetes not observed. Cell division irregular in 1-3 or more planes. Reproduction by liberation of solitary cells from a thallus (sometimes after rupture of the sheath), of groups of 2 or more cells, or by short, few-celled hormogonia. Hormogonia composed of small cylindrical cells, which enlarge and become spherical during further development. The single (type) species isolated repeatedly from garden soils and paddy fields in India (Uttar Pradesh, near Allahabad). Important model strains, used particularly for the study of atmospheric nitrogen fixation.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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