        Many leaf spots caused by Ramalina spp do not have a pale neurotic centre. To confirm Ramularia you need to see a white felty layer on the underside of these spots. If not present, they may develop if a leaf is placed on some damp kitchen paper in a plastic box for a day or two. There are no downy mildew on this host to get confused with.
