Kamptonema O.Strunecký, J.Komárek & J.Smarda, 2014
Holotype species: Kamptonema animale (Gomont) Strunecký, Komárek & J.Smarda
Original publication and holotype designation: Strunecký, O., Komárek, J. & Smarda, J. (2014). Kamptonema (Microcoleaceae, Cyanobacteria), a new genus derived from the polyphyletic Phormidium on the basis of combined molecular and cytomorphological markers. Preslia (Prague) 86: 193-207.
Description: Filaments solitary without sheaths, or with very fine, facultative and diffluent sheaths, sometimes with several to many trichomes associated more or less in parallel without common firm sheaths. The fascicles are not enveloped in slime. Trichomes simple, cylindrical along their whole length (up to the end), uniseriate, pale bluegreen, slightly constricted or unconstricted at cross-walls, motile, (2.5) 3-5 (5.3) µm wide. Cells isodiametric or slightly longer or shorter than wide. End cells rounded, bent and hooked without calyptra, 2-3 end cells usually bent or folded from the longitudinal axis, with distinct movement. All cells are capable of division (without meristematic zones). The cell content is heterogenous, sometimes with a slightly more distinct peripheral chromatoplasma. Arrangement of thylakoids in cells is parietal or semiparietal with a circular pattern containing bundles of thylakoids, crossing the interior of cells. Solitary granules of polyphosphate and cyanophycin are present in cells.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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