April 2011. Spots and blotches on Quercus aff canariensis from the Royal Botanic Gardens, Melbourne. It was not sure if the symptoms were due top environment or pathogen.
It was suggested that the member contact the University of Kentucky Research and Education Center. On this page, for instance, there are lots of images of fungi: http://www.forestryimages.org/search/action.cfm?q=quercus%20fungi. Elsewhere there are labs and contacts, eg: http://www.forestryimages.org/browse/detail.cfm?imgnum=5405365
