ok to burn this? (pic)

This growth on the bark is like rubber.

Itll burn off in the stove, Just split and stack it off the ground and the growth will die off. Wont hurt anything to burn it.

I wouldn't worry about the fungus, but I reckon those rounds aren't ready to burn.

Get it split & stacked & dried out.
Most of the fungus will fall off during splitting & stacking.
What doesn't will dry & burn just fine next year.

Agree with the others on this. I've seen worse for sure and it still burned good.

Elusive, I just noticed that you not only are from Michigan but are a new member. Welcome.

No. Not okay to burn in an insert. It will however burn okay in a gassification boiler. Please deliver to my house the next time you are up this way and I will take it off your hands for you.
