there is some debate about tar spot being a pollution monitor (for sulphur dioxide). The correlation between lack of tar spot and urban areas has been linked to the clearance of leaf litter in urban areas. Germinating spores from fruitbodies (apothecia of a cup fungus) appear on the black stroma in the spring and re-infect the living trees. If the litter is removed then there is no innocolum - see Leif a& Fowler 1988, New Phytologist, v108, p175
