I have had a quick dig and there are some bootlace like roots. Are they from the tree or a fungus? They are 2-3 mm, and quite tough and rubbery. The outside dark skin peels off and the tough bit is inside, a yellowy colour. When I have photographed the small bits I have I will post. They are more grey than black as they dry out.
