Notes

Cells spherical to weakly elliptical, 8-15.0 μm in diameter (Fig. 4 a-c; Fig. 6 a). In culture cells were spherical, up to 19 μm in diameter, the cell wall sheath <0.5 μm. Chloroplast plate-like, sometimes lobed, covering most of the cell. One pyrenoid present, at times difficult to distinguish. In the natural population the cell wall sheath was thick, up to 1.5 μm. Colonies of daughter cells tightly packed, forming wedge-shaped colonies in spherical to elliptical clusters. Endolithic, forming a fine linear layer (flake-like) 0.1-0.4 mm below surface of sandstone.
