Weird Tree Bark

No idea what this stuff is, but it’s neat.

  1. Love this shot. Very neat.

  2. Hey, I’m trying to find out what this is– I found two examples (the same structures, although they have far fewer of them) in my own area. I think it’s a disease of some sort. Do you know what species this tree is or what county it’s in?

    Great shot, by the way!

    • Hey bob, thanks for the interest, I’ll track down what info I have and get back to you shortly

  3. I recently saw this crazy bark on a tree in my area and have been trying to figure it out too. Good call on the tree disease- that seems very reasonable! I don’t know much about botany though so I would love to hear if you find anything!

    • I pulled one of the structures off one of these trees, as well as twigs from two branches (one had flower buds ready to bloom and the other had what I thought were fruits or nuts) and also took some photos on my cell phone. I showed these to the host-plant resistance (HPR) expert at my university (that field is a fancy term for plant defense against herbivory), and he thinks it’s a beech tree. He said the bark formations are probably natural and that the fruit/nut things I found are actually neither of those– they are galls caused by wasps. I found it interesting that if one twig on a a branch displayed the galls, so did every single twig on that branch. He said that most likely the wasp affects the entire branch if that’s the case.

      He wasn’t entirely sure about the bark, but that answer is at least a start. I have noticed that every single tree I’ve found of this species looks like this (including the galls), so even though it’s likely the healthy state, an infection is still possible as an explanation (considering the wasps managed to find all of them).

  4. Oh the ones I’ve found so far have been in Evansville (Vanderburgh County), IN. Useless to report a finding in nature if you don’t provide a location… ;)

    • I have no idea of the species, but this tree was in Cumberland County near Farmville, VA. That’s about as much as I know about it.

  5. Is there really a place called Farmville? lol…

  6. theres a tree like this outside my house and my girlfriend and I are trying to figure out what it is.
    Did you ever find out what is going on with the tree?
