Holotype species: Desertifilum tharense Dadheech & Krienitz
Original publication and holotype designation: Dadheech, P.K., Abed, R.M.M., Mahmoud, H., Mohan, M.K. & Krienitz, L. (2012). Polyphasic characterization of cyanobacteria isolated from desert crusts, and the description of Desertifilum tharense gen. et sp. nov. (Oscillatoriales). Phycologia 51(3): 260-270.
Request PDFDescription: Thallus thin, pale to bright blue green, filaments solitary or densely entangled, varying in length, filament motile through gliding and oscillation, sheath thin, colourless, attached to trichome (agglutinated), not constricted or slightly constricted at cross wall, trichome 2-7 µm wide, attenuated at the ends, cells cylindrical, isodiametric or up to twice longer than wide, sometimes slightly barrel shaped, cell content homogenous, gas vacuole present or absent, apical cells longconical and rounded apex, usually curved differentially. Reproduction by binary fission or formation of necridic cells. Moderately thermophilic, sensitive to high salinity. It differs from other genera of Oscillatoriales by the order of phenotypic features and substantial difference in the nucleotides sequence of 16S rRNA gene.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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.
