Anagnostidinema Strunecký & al., 2017
Holotype species: Anagnostidinema pseudacutissimum (Geitler) Strunecký, Bohunická, J.R.Johansen & J.Komárek
Original publication and holotype designation: Strunecky, O., Bohunická, M., Johansen, J.R., Capková, K., Raabová, L., Dvorák, P. & Komárek, J., (2017). A revision of the genus Geitlerinema and a description of the genus Anagnostidinema gen. nov. (Oscillatoriophycidae, Cyanobacteria). Fottea, Olomouc 17(1): 114-126, 4 figs.
Description: Colonies spreading, green to blue–green, mucilaginous, amorphous. Sheaths absent. Trichomes thin, mostly bright blue–green (aquamarine), usually straight or slightly bent, dispersed evenly and loosely without mat formation, unconstricted or only indistinctly constricted at cross–walls. Sheaths absent. Trichomes cylindrical, straight, not capitate, motile with intense gliding in the direction of the longitudinal axis, sometimes accompanied by bending and distinctive rotation, 1–3 µm wide. Cells usually 2–4 longer than wide, 4–8 µm long, sometimes with visible peripheral chromatoplasma, sometimes with evident carotenoid granules, without aerotopes, after division growing to the size of the mother cells before the next cell division. Apical cells in developed trichomes bent, narrowed and pointed–rounded, never calyptrate or capitate. Thylakoids parietal, with triangle or rhombic organization in transversal section. Reproduction by disintegration of trichomes in hormogonia without necridic cells.The most recent alteration to this page was made on 2023-03-03 by M.D. Guiry.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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