Large green lichen with a different growth pattern in the center. This one was about 8 cm in diameter. They were growing on most of the tree trunks.

Thank you Sarah, very interesting information and nice to know!
The center is different because that's where the reproductive bodies (apothecia) are located. The edge is the part that is continuing to grow, the youngest part of the lichen and so hasn't developed any apothecia yet.
