Lecidella elaeochroma f. elaeochroma

Lecidella elaeochroma is a very common epiphyte although it is quite variable in appearance. It can be found on smooth-barked trees and wooden fences. The granular thallus usually has a black prothallus edge and it often occurs in epiphytic mosaics with other species, e.g. Lecanora chlarotera. It normally bears lots of black apothecia.
