This pale pastel green lichen has similarities with the ones at Sightings 4647896 & 4664003. It has the overall shape, size and colour of 4664003 and to some extent the colour, and (though fewer of) similar black ‘hairs’ (photos 1), to Sighting 4647896, (especially seen in its photo 2). I am now starting to wonder if this is a single species of Lichen with changes in appearance at different life stages. This one is showing what I believe are fruiting bodies.
