Dear colleagues,

I received these photos from one of my forest pathology students and I must admit I've never seen these things before. Can anyone help?

Thanks!

Subject: Bumps on Beech

While I was at Harvard I found this beech tree with some interesting wart-like mounds on its bark. Is this normal for some beeches, or could it potentially be a paper topic? Do you know what it is?

Thanks!
