Thats what i'm thinkin'.......... theres fungus amongus.
it appears to be severely contaminated.
you should load that wood up, plus any other wood that has come within 50 feet of it and drop it off at my house for further evaluation. i'll study it carefully, allow it to dry in quaranteen, then i'll try burning it during the winter.
if it burns well, i'll let you know it was good.
