Description: Solitary cells forming irregular palmelloid aggregates. Cells round to ellipsoid or slightly irregular, mostly 5-12 µm long. Cell walls thin and smooth, with cellulose and pectin. Cells uninucleate; chloroplast massive and central, filling most of cell; pyrenoid single and central, with starch sheath. Asexual reproduction by division of protoplasts and by autospores; (2-) 8-18 spores per cells; released by rupture of parental wall. Autospores ellipsoid, 5-4.5 x 1.4-4 µm. Flagellated stages and sexual reproduction unknown. Pseudochlorella associated with lichens; reported from Austria. This alga requires further study and the taxonomic affinities are unclear. Genus traditionally assigned to Chlorellaceae. The central chloroplast and cell aggregates resemble Trebouxia. Solitary cells forming irregular palmelloid aggregates.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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