Crusty, deeply cracked, black lichen on granite just above high tide level. Pictures 1 and 2 are on the south-facing side of the rock; picture 3 is on the north-facing side where it is much thinner, but in the cracks in the rocks it looks like a miniature version of that on the south side. It is much harder to see the fine texture on this side.
