Gigantochloris Pascher, 1927

Holotype species: Gigantochloris permaxima Pascher

Original publication and holotype designation: Pascher, A. (1927). Die Süsswasser-Flora Deutschlands, Österreichs und der Schweiz. Volvocales = Phytomonadinae. Vol. 4 pp. 505. Jena: Fischer.

Description: Large, unicellular thalli spherical, ovoid, cylindrical or spindle-shaped (70-150 µm in length by 40-80 µm in width). Cell compressed along flagellar axis. Two rigid, isokont, anterior flagella are inserted at some distance from one another. Single, large chloroplast is cup-shaped but with perforations. Pyrenoids many and distributed throughout the chloroplast. Papillum absent. Eyespot small or absent. Asexual and sexual reproduction unknown. Gigantochloris only reported once from meltwater in Czechoslovakia. Chloroplast morphology, presence of pyrenoids, and rigid flagella distinguishes Gigantochloris from the similar Gloeomonas. No ultrastructural, biochemical, or molecular data are available for this organism.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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