Lobosphaera

Lobosphaera is a genus of green algae in the family Trebouxiaceae.

[2] It was originally described from soils in Austria,[1] but has since been found in freshwater habitats and as a symbiont within lichens.

Cells contain a single chloroplast that is parietal with marginal indentations.

Chloroplasts lack pyrenoids but have starch grains.

Reproduction is asexual and occurs by the formation of 4-32 autospores; these are released by the rupture of the parental cell wall.
