I believe it to be the leftovers of L.thysanophora. I’ve seen it several times now, always on maple (see #71161 too). I don’t know what happened to the lichen and how it died (death of old age?), but I’ve seen trees with some lichen still there and these circles next to them too (see observation #82417).
