Description: Cells oval or nearly spherical, slightly compressed dorsoventrally. Epicone larger than hypocone. Cingulum descending but cingular displacement very small. Chloroplasts present, eyespot unknown. Reproduction observed in G. uliginosa. Vegetative division takes place within the theca and the daughter cells exit through a slit formed between the precingular and cingular plates on the cell’s left side. Sexual reproduction induced by nitrogen starvation. Gametes similar to vegetative cells, but smalle. One gamete fuses head-on with the cingulum- sulcus region of the other gamete. Resting cysts spherical, warty, the warts apparently reflecting the plates of one of the gametes. Germination not observed but empty resting cysts observed in cultures.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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