Sorry I'm late in responding, but thank you Fleurisa and Edd for your interest. I just have to wait for final approval to fell the tree ( I live in a conservation area) and in the meantime...... do I dig out the fungus and the surrounding turf or perhaps wait for some colder weather to kill it off? The wet, mild conditions here are on the side of the fungus!!
I'm keeping a close eye on surrounding shrubs and trees - there are two more betula close by - much younger and very attractive multi-stemmed varieties and hopefully not quite so susceptible; am I correct in thinking that only older/weaker trees are prone to the problem??
Thanks again for your help.
