Thanks for that, would definately be interesting to see more research into this as the stuff I have read to date refer both to lichens obtaining nutrients via acidic breakdown of the substrate as you indicate, while at the same time exhibiting more growth in a basic environment - I wonder why this would be the case as the 2 certainly appear to conflict?
