This is a list of common names of lichen genera.
This list only includes genera common names that are widely used, as indicated by the common name either appearing in a peer reviewed scientific publication or in a scientifically reliable reference source.
An example is that "wart lichen" refers to at least five different genera in four different families.
For example, members of the genus Staurothele are commonly called "wart lichens", and also "rock pimples".
Other members may not share that trait, but are still referred to by the common name for the genus.
