Description: Colonies contain 4 cells attached to their parental cellular sheath (sac), forming a square. Cells ovoid and somewhat asymmetrical, each with two equal flagella, a stigma, two contractile vacuoles at the base of the flagella, and a massive cup-shaped chloroplast with single pyrenoid. Asexual reproduction by autocolony formation; akinetes sometimes formed. Sexual reproduction isogamous, forming walled aplanozygotes. Basichlamys is rare but cosmopolitan in freshwater. Basichlamys was described for Gonium sacculiferum Scherffel. It is distinguished from Gonium in lacking connections of the cellular sheaths of the constitutive cells, which attach only to the sac. Some authors do not recognize this genus and use Gonium sacculiferum.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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