Confidence: I'm as sure as I can be.
Notes: This is one of the dog lichens with a pubescent upper surface. To reliably identify these, the veins and the rhizines of the lower surface need to be examined, so I am not going to ID it to species. However, the large, recurved, ear-like, pinkish apothecia arising from the lobe margins remind me of P. didactyla, which is not uncommon on soil patches (in natural turf, in lawns and as a colonist of neglected flower-beds). The relatively small size (as judged by the grass leaves) supports this. The diagnostic character for P. didactyla is that young lobes have well delimited, round soralia (asexual structures) on the lobe surfaces, but these disappear completely by the time the thallus is mature enough to produce apothecia. Looking near the bottom of the photograph, there MIGHT be residual scars from soralial production on a couple of the lobes. Related species include P. canina, which normally has more visible, indented, "bullate" veins on the upper surface, and P. rufescens, which usually has somewhat larger lobes with crisped edges. I cannot rule out either of these species.
