Unknown Lichen

Observation - Unknown Lichen - UK and Ireland. Description: Found growing on a sea defence boulder, which received very little, if at all, light. Clearly some apothecia developed and the thallus seemed 'feathery' at the edges which I've never seen before. Any suggestions will be very welcomed, thanks.
