My understanding from recent

My understanding from recent work is that these brooms can occur as a result of either T. betulina or a phytoplasma, and need careful examination of the gall to differentiate. Not that easy unless you have a well-trained squirrel! A gall-expert would need to advise on how to deal with sight-records like this.
