This one is called Parmelia subrudecta which also attaches to trees in flat greenish-grey patches. It has some moss intertwined with it – possibly Hypnum cupressiforme.

I found this one on a rock in the garden.

This Cup Lichen (Cladonia pyxidata) which produce broad cups from which spores are generated. This a close up so you need to get quite near to see these little rows of coronets.
