Description: This apple-green foliose, mainly epiphytic lichen could only be confused with F. caperata (described elsewhere), but differs in several respects. F. soredians has flatter, variously notched, lobes that appear almost glued to the substratum. The lobes produce fine, powdery soredia compared with the coarse soredia of F. caperata. The habitat is also different, preferring dusty, wayside tree bark, timber fencing and brick wall tops to acid-barked trees and rocks. This is a species which is much overlooked but is currently expanding its range in Ireland. North-east and south-west Ireland.

Key Identification Features:

• The apple-green colour, notched lobe ends, powdery soredia and flattened thallus should enable the beginner to distinguish it
• It prefers sunny, dust-contaminated sites, for example, wayside trees and old fence timbers, from where it can spread to rocks and walls.
