Stereocaulon

Stereocaulon is a genus of lichens. Members of Stereocaulon are commonly called rock foam lichens.^[1][2] Photobiont partners of Stereocaulon include green algae from the genera Asterochloris, Chloroidium, and Vulcanochloris.^[3] Stereocaulon is difficult to ID to species, but there is a high diversity of species within the genus.
