Planktolyngbya Anagnostidis & Komárek, 1988

Holotype species: Planktolyngbya limnetica (Lemmermann) Komárková-Legnerová & Cronberg

Original publication and holotype designation: Anagnostidis, K. & Komárek, J. (1988). Modern approach to the classification system of cyanophytes. 3. Oscillatoriales. Archiv für Hydrobiologie, Supplement 80(1-4): 327-472, 35 figs, 13 tables.

Description: Filamentous; filaments solitary, with thin, simple, colorless, firm sheaths, rarely false-branched; trichomes cylindrical, isopolar, straight, waved, coiled to more or less screw-like or spirally coiled, narrow, to 3 _m wide, uniseriate, usually not narrowed to the ends, indistinctly constricted or unconstricted at the crosswalls, always nonmotile. Cells cylindrical, rarely shorter than wide, usually longer than wide (to several times), without aerotopes or with facultative polar aerotopes, sometimes with solitary granules; end cells rounded or narrowed-rounded, always without calyptra. Cell content pale gray-blue, blue-green, yellowish or olive-green, thylakoids localized peripherally along the cell walls. Cell division by the crosswise binary fission, perpendicular to the long axis of a trichome, daughter cells grow Å to the original size before the next division. All cells capable of division. Reproduction by fragmentation of trichomes without necridic cells into nonmotile (?) hormogonia. Planktonic species, usually in large, mesotrophic reservoirs; several species limited to tropical and warm temperate zones, several species presumably nordic.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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