Original publication and holotype designation: Skuja, H. (1964). Grundzüge der Algenflora und Algenvegetation der Fjeldgegenden um Abisko in Schwedisch-Lappland. Nova Acta Regiae Societatis Scientiarum Upsaliensis Series 4 18(3): 1-465, 59 pls.

Description: Cells sometimes solitary but usually a few to many united in a mucilaginous colony, the cells lying within swollen and gelatinized mother cell walls. Cells globose, 8-12 µm in diameter, the cell wall smooth except for one small wart- or beak-like thickening, 3 x 0.5 µm. Chloroplast single, stellate, with one pyrenoid. Asexual reproduction by 2-4-8 autospores, released by mucilaginization or rupture of the mother cell wall. Colonies often comprised of cells of several generations. Flagellated stages and sexual reproduction unknown. Chondrosphaera, planktonic or metaphytic, freshwater, reported only from Argentina and Sweden.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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