I looked at your photos again.
At my first view it irritated me that you wrote that this lichen grows on the boulder. I think the lichen doesn't grow directly on the boulder!
When looking closer, one can see many wooden textures in front of the boulder and also a thin layer of soil on top of the boulder. That's where your lichen grow.
With no visible "stems", and wood or soil it grows on, I'm pretty sure it's the Icmadophila ericetorum lichen, also called Candy Lichen. 

 @f2f7ab5b an apt nickname, Candy! 

 @f2f7ab5b also, upon review I realized you are right that picture was one of the several I took in the same area, and I mixed it up with the Boulder covered lichen. It was indeed a fallen tree! The boulder was very plain, not as populated with moss etc. I so enjoy your photos and comments so much that this has reminded me to be a little more careful when posting my descriptions. 💚
