According to draft key for Ways of Enlichenment, the only species that match: abundant rhizines and frosted reticulately-ridged upper surface are U. virginis and U. cylindrica. These two are distinguished by apothecia smoothness, presence of cilia on margins, and color of lower surface:

U. virginis – pinkish below, smooth apothecia, no cilia at margins but may appear to have some because of long rhizines protruding from below
U. cylindrica – tan to brownish below, gyrose (stipitate?) apothecia, often with cilia on margins

Both are to be expected in such a location.
