Description: Algae eucaryoticae, chlorophyllis a et c2 . Corpora principalia cellularum amoeboidearum sessilium loricas cingentes et reticulopodiis conjunctis meroplasmodium facientia. Lorica in planitie applanata ostiolis lateralibus. Spatium inter loricam corporemque principale saepe protuberationibus cytoplasmatis. Chloroplasti in gregibus aggregati, per pyrenoides dense agglomeratas in area centrali gregum uniti, partibus pigmentiferis chloroplastorum radiantibus. Pyrenoides agglomeratae vesicula galeanti unica gregis instructae. Multiplicatio vegetativa cellularum meroplasmodii per bipartitionem effecta; filia una sedentaria in lorica manet, altera in amoebam migrantem vel natantem sine flagellis commutat. Eukaryotic algae with chlorophylls a and c 2 • Main cell bodies of sessile amoebae form enclosing loricae and a meroplasmodium by fusing reticulopodia. Lorica on plane surfaces flat with lateral pores. Space between lorica and main cell body frequently with protuberances of cytoplasm. Chloroplasts grouped in complexes, united by densely aggregated pyrenoids in the center of the complexes with radiating pigmented chloroplast lobes. Pyrenoid groups are covered by a single capping vesicle. Vegetative reproduction occurs by binary division; one daughter cell remains in the lorica of the mother cell, the second cell becomes a migrating or floating amoeba without flagella.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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