Black rubber lichen
Coming home from a walk I noticed some dark patches mixed up with fragments of moss on the gravelly drive in front of the house and, on closer inspection, these turned out to be the lichen Collema tenax, much swollen after recent rain.
I have seen this at Pagham Harbour and Lydd, but not at South View before so I wonder if I might have introduced it on my boots. Mind you, though common it is very easily overlooked with its unprepossessing appearance and dark colour.
