Glaucospira Lagerheim, 1892
Lectotype species: Glaucospira agilissima Lagerheim
Original publication: Lagerheim, G. (1892). Notiz über phycochromhaltige Spirochaeten. Berichte der deutschen Botanischen Gesellschaft 10: 364-365.
Type designated in: Geitler, L. (1942). Schizophyta: Klasse Schizophyceae. In: Die natürlichen Pflanzenfamilien, Sweite Auflage. (Engler, A. & Prantl, K. Eds) Vol.1b, pp. 1-232. Leipzig: Wilhelm Engelmann.
Description: Filamentous; filaments (trichomes) solitary, thin (up to 3 _m wide), without sheaths, regularly screw-like coiled with wide and more or less long screws, usually intensely motile (rotation), sometimes slightly flexible, cylindrical, not attenuated to the ends, not constricted at the crosswalls. Cells pale blue-green or yellowish, with homogeneous content, sometimes with few fine granules, probably always longer than wide. Cells divide crosswise to the axis of a trichome. Reproduction probably by the trichome dissociation. Few species known from plankton of lakes and reservoirs and from metaphyton among aquatic plants in swamps, usually in tropical regions (E. African lakes, Cuba, Ecuador, etc.). One species known from N. Europe, one from thermal springs in Yellowstone Park (USA).

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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