Description: Solitary cells not embedded in mucilaginous matrix, and attached to planktonic debris by colorless and often stratified basal disk. Cells 4.5-12 x 2.8-4.5 µm, oval, fusiform or egg-shaped, often with unequal, rounded ends. Cell walls smooth. Cells uninucleate; chloroplast single and parietal, without pyrenoids. Asexual reproduction by autospores; 2-4 (-8) per sporangium released through upper end of sporangium. Attachment disc often developing prior to spore release. Flagellated stages and sexual reproduction absent. Pseudococcomyxa in freshwater; in culture attached to sides of culture vessels, in nature planktonic and attached to debris in water reservoirs or peat bogs; reported only from eastern Europe. Genus most comparable to Chlorobion and Podohedriella.

Numbers of names and species: There are 6 species names in the database at present, of which 5 have been flagged as accepted taxonomically on the basis of the listed literature under the species name. In some instances, opinions on taxonomic validity differ from author to author and users are encouraged to form their own opinion. AlgaeBase is a work in progress and should not be regarded as a definitive source only as a guide to the literature..
Names: ('C' indicates a name that is accepted taxonomically; 'S' a homotypic or heterotypic synonym; 'U' indicates a name of uncertain taxonomic status, but which has been subjected to some verification nomenclaturally; 'P' indicates a preliminary AlgaeBase entry that has not been subjected to any kind of verification.

Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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