    Hello all,

    Came across this the other day. It is a two stem Norway maple, where on stem is covered in what looks to be many small cankers all over the main stem and branches. Any ideas? DSC02032.JPG DSC02035.JPG DSC02036.JPG DSC02038.JPG DSC02040.JPG DSC02041.JPG DSC02043.JPG

    Some look like small burls, some cankers, others a gall. Weird.
