'''''Stereocaulon''''' is a [[genus]] of [[lichen]]s. Members of ''Stereocaulon'' are [[common name|commonly]] called '''rock foam lichens'''.<ref>[http://eol.org/pages/16606/overview Snow Lichen (Stereocaulon), Encyclopedia of Life]</ref><ref name =USDA>[https://plants.usda.gov/java/nameSearch USDA Natural Resources Conservation Service Name Search]</ref> {{lichengloss|Photobiont}} partners of ''Stereocaulon'' include [[green algae]] from the genera ''[[Asterochloris]]'', ''[[Chloroidium]]'', and ''[[Vulcanochloris]]''.<ref name="Sanders & Masumoto 2021"/> ''Stereocaulon'' is difficult to ID to species, but there is a high diversity of species within the genus.
