Parmelia saxatilis

P. discordans, P. ernstiae, P. hygrophila, P. imbricaria, P. mayi, P. omphalodes, P. pinnatifida, P. serrana, P. submontana, P. sulymae, and P. rojoi are other members of this complex.

[8] The lichen has a greenish-gray to bluish-gray thallus that can turn brown in exposed locations.

Parmelia saxatilis is used to make dyes with deep red-brown and rusty-orange colors.

[9][10] A somewhat similar species complex with a cosmopolitan distribution is the Parmelia sulcata group, generally growing on trees.

Because the lichen is common, abundant, and widely distributed with a stable population size, it is considered of least concern.
