Fungi or Gall

Please try to include photos to show all parts of the fungus, eg top, stem, and gills.
Note any smells, and associated trees or plants (eg oak, birch). A spore print can be very useful.

Fungi or Gall

Post by NellyDee » Wed May 30, 2018 1:07 pm

This growth is on a very old beech tree I am not certain if it is fungal or a gall. the large growths I have seen on trees were generally a lot smoother or lined almost taking on the bark look. What is confusing me with this is appears crumbly and as if something (possibly bird) has made it it's nest. I don't suppose you could point me in the right direction?

Hi Nelly,

I think this is what is generally known as a "burr". (Americans would call it a "burl").

They are produced as a result of some sort of injury or stress to the tree causing localised & greatly increased cell division, producing these deformed growths.
They can, I believe, be triggered by bacterial or fungal means.

Regards,
Mike.
