Prasiola stipitata is a small green alga of the family Praiolaceae.

This alga grows to no more than 1 centimeter long, is fan shaped with a distinct stipe.

[1][2] P. stipitata thrives in high-nutrient habitats and is therefore often found in the spray water zone of shores frequented by sea birds.

[5] Recorded mostly from cold-temperate regions on both hemispheres, e.g. Iceland, the Faroes, Atlantic coasts of North America and Europe, including Great Britain and Ireland, as well as from Australia and New Zealand.

[2][6] This species has also been recorded at the Antipodes, Auckland and Campbell Islands.
