Gomontiella Teodoresco, 1901
Holotype species: Gomontiella subtubulosa Teodoresco
Original publication and holotype designation: Teodoresco, E.C. (1901). Sur le Gomontiella, nouveau genre de Schizophycée.. Verhandlungen der kaiserlich-königlichen zoologisch-botanischen Gesellschaft in Wien 51: 757-760, pl. IV.
Request PDFDescription: Filamentous; filaments (trichomes) solitary, uniseriate, without sheaths, straight, short, flattened from sides and composed of C-like curved cells forming a tubelike formation with a narrow or wide opening along the whole trichome length, which can be localized straight or slightly screw like on the trichome; crosswalls slightly constricted or unconstricted, trichome ends not attenuated or slightly narrowed. Cells very short, flattened and curved, at the cross section in the form of "C". Heterocytes and akinetes lacking. Cell division crosswise to the long axis of a trichome. Reproduction by the dissociation of trichomes in hormocytes. The type species described from the drying pools on rocks in Romania. The validity of this genus was several times questioned, because similar flattened and tube-like formations occur sometimes in different Oscillatoria species as a drying effect (comp., e.g., Anagnostidis and Schwabe 1966). However, from the original type material exist several exsiccates (isotypes), which confirm the existence of this species. The genus was revised by Claus (1966), who described other species from Hungary (aerophytic in caves, thermal springs); however, the genus needs in each case further investigations.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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