Observation - OU S159 - Foliose Lichen Identification - UK and Ireland. Description: These types of foliose lichen account for the total I found during my OU S159 lichen hunt. They appear everywhere locally (rural mid-Somerset) on bark and fences. Could anyone help me with specific species identification please?
