Porocyphaceae

The Porocyphaceae are a family of lichen-forming fungi in the order Lichinales. Members of this family are typically small, dark-coloured lichens that form partnerships with cyanobacteria and grow on rocks, soil, or occasionally tree bark in well-lit areas that experience periodic wetting. The family was originally established in 1855 but was largely ignored until a 2024 study greatly expanded its scope to include genera previously placed in several other families. Porocyphaceae species are found worldwide, though they are uncommon in densely shaded forests.
