On a recent hike in Germany I came across a tree that I never saw before. Its entire trunk was covered with holes. The bark wasn’t cut or punctured, just weirdly bent inwards. There was just this one tree that looked like this. Unfortunately, it didn’t have leaves yet.
Do you know what kind of tree that is? Or is it some kind of virus / cancer etc. causing this?

I’ve never seen anything alike. Might also be some older healed damage to the bark? Alas, the picture isn’t high-res and detailed enough for me to recognize the genotype or type. Seems a bit mossy, right? My guess is fagus, but with little confidence.
It went all the way up the tree and pretty evenly distributed, didn’t look like damage to me.
Lemmy doesn’t allow me to upload the pics in full resolution, so I uploaded them to an external pic hoster: https://ibb.co/ns9syW7V https://ibb.co/7ds4ZP1t https://ibb.co/Q32f29mG https://ibb.co/nqnt6GC9
Most probably the tree is a fagus. What illness or damage though I don’t know.
Thank you! The forest is full of pine, oak and beech trees. The bark doesn’t look like oak or pine and didn’t have needled.Thus, fagus is quite likely. It would still be very interesting if someone else has an idea of what might have caused that deformation.
