Doliocatella L.Geitler, 1933

Holotype species: Doliocatella formosa Geitler

Original publication and holotype designation: Geitler, L. (1933). Diagnosen neuer Blaualgen von den Sunda-Inseln. Arch. Hydrobiol. Suppl. 12: 622-634.

Description: Filamentous-thallose; filaments attached to the substrate, erect, joined to the fasciculate, brownish thallus, up to 0.5 cm long, but without special adhering cellular organelles or discs. Trichomes uniseriate, laterally (usually unilaterally) true-branched (T-type), composed of barrel-shaped cells. Basal parts of filaments thick, torose, not branched, younger parts thinner, more or less cylindrical, morphologically different from basal filaments; in upper parts of filaments common ramification, branches short, arcuate. Sheaths thin or thick, colorless up to yellow-brown, sometimes copying the moniliform shape of trichomes; around cells in old filaments thick envelopes. Cells with homogeneous or granular (often peripherally) content, more or less isodiametric old cells sometimes vacuolized, cells in hormogonia granular. Heterocytes and akinetes missing. Cells divide crosswise or lengthwise (before the branching). Reproduction by hormogonia, usually 5-15-celled, which arise on the ends of short branches, and probably by fragments of thallus. D. formosa has been found only in acid waterfalls, (pH = ca. 5.5) in Indonesia (Sumatra).

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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