[IUFRO RG 7.02 FORPATH] FW: Bumps on Beech

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!

Is this normal for some beeches, or could it potentially be a paper topic? Do you know what it is? Thanks! -Diana
