There are soralia at the tips of these

if you look really closely at the full-size images. That rules out U. strigosa (strictly eastern species complex anyway, I think), U. intermedia, etc. The way the soralia clump toward the tips and the sparse branching with really thick main branches suggests U. cornuta (or one of those species, in any case, you may need chemistry to narrow it down to a species, I’m not sure). The main identifying characteristic of this group is that the main branches are sort of “inflated” and constricted at the joints; they tend to be coastal.
