Original publication and holotype designation: Jasser, I., Panou, M., Khomutovska, N., Sandzewicz, M., Panteris, E., Niyatbekov, T., Lach, L., Kwiatowski, J., Kokocinski, M. & Gkelis, S. (2022). Cyanobacteria in hot pursuit: Characterization of cyanobacteria strains, including novel taxa, isolated from geothermal habitats from different ecoregions of the world. Molecular Phylogenetics and Evolution 170(170454): 1-18, 12 figs.

Description: Filaments mostly solitary, at times with multiple hormogonia in a common sheath, or with loose nodule formation (Fig. 7AB). Sheath clear, thick and widened, three to four layers (Fig. 7C-D). Trichomes straight, flexuous, or entangled within a sheath into a loose nodule, sometimes spirally coiled, slightly constricted at the cross walls, with slow gliding motility observed in trichomes lacking sheath, not tapered. Cells mostly shorter than wide, becoming isodiametric to slightly longer than wide before division, without aerotopes, sometimes with cyanophycin granules in cytoplasm (Fig. 7A-B); with parietal thylakoids. Apical cells rounded, without calyptra. Reproduction by trichome fragmentation via disintegration at necridia (Fig. 7A,C,E).

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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