Grey Crustose Lichens

Observation - Grey Crustose Lichens - UK and Ireland. Description: On acid rocks at Bradgate Park, Charnwood Forest, Leics. In the last photo, it's the little island in the map lichen that is of interest (and the same/similar species at the top edge). Any thoughts appreciated, any reluctance understood!
