Description: Large, unicellular thalli spherical or ovoid. Two isokont, anterior flagella are inserted at some distance from one another. Chloroplasts many. Pyrenoids absent. Stigma usually present. Two anterior contractile vacuoles inserted between flagellar bases. Papillum present but broad and flattened. Flagellar root system cruciate and composed of four sets of microtubule systems. Phycoplast system of microtubules, with a foci centered in the flagellar root and termed a radicoplast, develops in the plane of cytokinesis. Asexual reproduction by zoosporogenesis. Two to eight zoospores produced. Palmella stages have been reported. Sexual reproduction (heterogamy) known only from G. tecta.

Comments: Gloeomonas reported in calcareous lakes, associated with Sphagnum, and in dystrophic water systems. Gloeomonas is distinguished by the numerous chloroplasts and the widely separated flagellar insertion points. Domozych has studied investigated ultrastructural and cytochemical aspects of the endomembrane system in Gloeomonas kupfferi. Segaar and others examined ultrastructure of cytokinesis in the same species. No other 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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
