I was delighted to find this little cluster of lichen fruits. It was on a fallen oak branch. The entire formation is about an inch and a half wide.

Punctelia also has spots, but they are holes punctured all the way through the cortex. These spots are just pale discolorations (from uneven distribution of algae below the cortex). You’d also find that this is white underneath, separating it from most of the “parmelioid” lichens like Punctelia.

I suspect that this is Physcia, which are generally rosette lichens. In fact, they are called rosette lichens, but they will wrap themselves around thin branches, and in this case it might have taken on that interesting shape by conforming to the shape of the branch underneath it. They are generally grayish white, but they can look greenish like this when they are damp.

…..and i was delighted to share your observation of it! nice shape!
