Pandorina
Bory 1824

Family: Colonies consisting of a fixed number of cells (Illustrations of The Japanese Fresh-water Algae, 1977).
Genus: Colony spherical; 8-16 cells of similar size, close together, mutually compressed; 2-layered gelatinous envelope; cells with 2 equal-length flagella; 2 contractile vacuoles anterior; nucleus central (Illustrated Guide, 1985). Sexual reproduction by isogamy (An Illustrated Guide to Freshwater Zooplankton in Japan, 2000). Sexual reproduction by iso- or anisogamy (Süßwasserflora von Mitteleuropa 9, Chlorophyta I, 1983)

Palmella

Family: Colonial; cell body spherical; without pseudo-flagella (immobile); chloroplasts one, 2 or 3 in number, with or without pyrenoids (Illustrations of The Japanese Fresh-water Algae, 1977).
Genus: Colony within a gelatinous bag; cells uniformly arranged at the peripheral matrix; cell body spherical or ellipsoidal without pseudo-flagella; 2-4 cells form a small subset; a single chloroplast cup-shaped, with a pyrenoid (Guide book to the "Photomicrographs of the Freshwater Algae", 1998). Small colonies planktonic or large ones attached to other substrates (Illustrations of The Japanese Fresh-water Algae, 1977
