On trunk of a deciduous tree at forest edge.
On a large old tree in the garden.
What I found to be interesting about this lichen was that it was somewhat brittle. It took me a while to find this type of lichen, but once I did, I saw it everywhere. It has loosely appressed leaves. It great alongside other lichen, and seemed to be located mostly on branches or twigs that were smaller (a few inches in diameter). Although it likely grows on larger trunks, I only saw it on smaller branches, like on this Maple.
