Heteroleibleinia (Geitler) Hoffmann, 1985

Holotype species: Heteroleibleinia rigidula (Kützing ex Hansgirg) L.Hoffmann

Original publication and holotype designation: Hoffmann, L. (1985). Quelques remarques sur la classification des Oscillatoriaceae. Cryptogamie, Algologie 6: 71-79.

Description: Filamentous; filaments solitary or in groups, heteropolar, joined with one end to the substrate (usually by a pad or a short leg) and with free second end, with simple, firm, colorless, thin sheath enveloping the trichome and open at the apex. Trichomes thin, mainly up to 4 _m wide, uniseriate, simple, Å straight ("starr"), curved or slightly flexuous, not attenuated at the ends, constricted or unconstricted at the crosswalls. Very rarely false branching with one lateral branch, after division of trichomes between two vegetative cells. Cells shorter to longer than wide, cylindrical or barrel-shaped; end cells rounded or conically rounded, without aerotopes. Heterocytes and akinetes lacking. Cell division by symmetrical crosswise binary fission, cells grow into the original size before the next division. Reproduction by motile hormogonia, escaping from the apical part of trichomes by help of necridic cells (?). Hormogonia join by one end to the substrate and germinate at the opposite end. All species occur in aquatic habitats, where they grow attached to different substrates (wood, stones, water plants, other algae, etc.). They occur in freshwater, as well as in marine biotopes. One species is epizoic on planktonic crustaceans. The genus is known worldwide, however, several species have limited areas of distribution or are known only from few localities. Not yet in culture.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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