Substrate Dependent Growth: The asbestos roof of a factory in Petersfield. The roof is made from two types of asbestos  that result in subtle changes in its microgeography.  The asbestos that makes up the larger area of roof is  inimical to the orange lichen but set within this are small panels of a different kind of asbestos that allows the same lichen to flourish.
