Holotype species: Pseudospongiococcum protococcoides Gromov & Mamkaeva
Original publication and holotype designation: Gromov, B.V. & Mamkaeva, K.A. (1974). Morphology and ultrastructure of some chlorococcal algae from the collection of algal strains in Leningrad University. I. Pseudospongiococcum protococcoides gen. nov. sp. nov.. Algological Studies/Archiv für Hydrobiologie, Supplement Volumes 10: 1-9.
Taxonomic status: currently recognized as a distinct genus.
Gender: This genus name is currently treated as neuter.
Description: Solitary cells, forming loose aggregates. Cells spherical to ellipsoidal, when young, 6-8 x 4-5 µm, later to 25 µm diameter. Cell walls thick and smooth. Cells uninucleate when young, later multinucleate; chloroplast single and parietal, spongy to net-like; pyrenoids initially single and eccentric, later becoming multiple, with distinct starch sheath. Asexual reproduction by autospores; 2-32 spores per sporangium; released by tear in sporangial wall, but sometimes remaining in sporangial wall for extended period. Flagellated stages and sexual reproduction unknown.

Comments: Pseudospongiococcum was isolated from soil; reported only from Krim in former USSR. Komárek and Fott (1983) consider Pseudospongiococcum similar to Capsochloris Dangeard, a marine alga.
Numbers of names and species: There is only one species or infraspecific name in the database at present, which has 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.

Verification of data
Users are responsible for verifying the accuracy of information before use, as noted on the website Content page.
Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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.
