Since the branches are nearly horizontal, the water doesn't drain completely and quickly. Water droplets and thus moisture stay along the lower surface of the branches for longer even after rain stops. This moisture would have attracted growth of some lichen or fungi/(algae?) and when it dries up, it becomes dark. May be b'cos its dark, its called as Krishna Kadamba (like Krishna Tulsi for the purplish form of Tulsi) denoting the dark complexion of Lord Krishna. Its just my perception.
