Description: Thalli colonial, spherical to irregular, with numerous ovoid to globose cells embedded in a structureless gelatinous matrix. Colony size variable, and species specific, 150 &m to > 5 cm. Colony growth by division of cells into 2-4 daughter cells. Cells with two apical flagellate; slightly motile within matrix. Cells uninucleate with 2 contractile vacuoles; chloroplast single, parietal and cup-shaped; pyrenoids and eyespots present or absent. Asexual reproduction by budding or fragmentation of colonies. New colonies also initiated by zoospores, 2-4 produced within parental cells, released by rupture of outer colony membrane. Sexual reproduction unknown. Gloeococcus aquatic or in soil; reported from North America and Europe. Taxonomic placement uncertain and requires ultrastructural study.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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