Strange looking growths on trunk of Silver Birch tree. The growths went a considerable distance up the trunk- getting smaller the higher they were. This particular tree had triple trunks but only one trunk had growths. Tree, which was in leaf, looked healthy. Photo taken today 29 September 2023. Location: Edenbridge, Kent, England Any ID appreciated. Thank you
Yes, a young Birch Polypore fungus - sadly, it means the tree's days are numbered. It'll live for a few years yet, but not much more.
