Thought I seen it all when it come to birch trees then I saw this today! Explain what it is please .

 

[david1]

my guess torn off branch years ago, not healing very well.

how high is it ?

 

[Teepee]

Birch wings.

Guessing the trunk's cracked in the cold and some growth altering microbes have caused the abnormal growth.

It's a rare forest clam, you never eaten one?

Seriously it looks like a damaged branch that's fixing itself through a mix of compartmentaisation and faciation.
