Original publication and holotype designation: Copeland, J.J. (1936). Yellowstone thermal Myxophyceae. Annals of the New York Academy of Sciences 36: 1-232.
Request PDFDescription: Thallose; thallus membranous, leathery or fibrous, macroscopic up to 1 mm high, composed of more or less free, horizontally growing, densely packed, slightly flexuous filaments of the same morphology, with true, lateral branched trichomes, and from more or less erect, usually pseudodichotomously branched filaments (T- and V-types of branching); pseudodichotomous branches arise by longitudinal division of the apical cells, lateral branches of intercalary cells; filaments usually crooked, somewhat roughened, cylindrical. Trichomes Å cylindrical, torulose, uniseriate, distinctly constricted at cross-walls, enclosed in colorless or yellow-brown, firm, thick, lamellated sheaths, with apical growth. Cells subcylindrical, barrel-shaped to ellipsoidal, longer than wide; end cells rounded, sometimes slightly up to distinctly enlarged. Heterocytes and akinetes not observed. Cell division evidently by the crosswise, perpendicular fission. Reproduction by few-celled hormogonia, which separate at the ends of branches. The single species known still only from Yellowstone National Park, USA. Terrestrial, atmophytic near thermal springs (places influenced by hot steam). A little known genus.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera,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