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.

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.

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Some of the descriptions included in AlgaeBase were originally from the unpublished Encyclopedia of Algal Genera, organised in the 1990s by Dr Bruce Parker on behalf of the Phycological Society of America (PSA) and intended to be published in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