Description: Cells solitary, spherical, (3.5)-15-(23) µm in diameter, with thin cell walls lacking localized thickenings. Chloroplast single, parietal, with delicate to deep marginal indentations, without pyrenoid. Starch grains within the chloroplast. Asexual reproduction by formation of 4-32 autospores released by rupture of the mother cell wall. Sexual reproduction and flagellated stages unknown. Lobosphaera, edaphic, apparently known only from the type locale in Austria. Similar to Lobosphaeropsis Reisigl which, however, possess a pyrenoid.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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