Greenish mildew/mold on firewood

[Fivehorizons88]

I noticed this dark greenish/blueish powdery mildew on my firewood (the color in the picture makes it look darker than it actually is)
It is two years seasoned and top covered out in the open.
Has anyone seen this before? Any concerns with burning or should I toss them aside?

thanks all!

just burn it as long as it's dry enough. Does not look punky, so you won't see a difference in heat output.
But even punky wood (if dry) will burn (just not with as many btus produced).

I would avoid stacking much of this in your home, given mold spores spreading into lungs etc. I.e. take what you burn into the home one day in advance so it gets up to temperature, and store it out of fan flows etc.

Thanks for the reply - that's what I was thinking but wanted some thoughts on it. Come fall and winter, I store the wood under my outdoor covered porch and only bring in a handful at a time so I should be good there.

thanks again!

I had a bunch of black walnut that got moldy one year. I can't even remember when it was cut but I'm guessing it was spring... Lots of sugar in black walnut sap in the spring. The mold on mine was mostly on the log ends. I kept a bristle brush out by the wood pile, and brushed it off before I brought it in the house. It burned just fine, nothing to worry about there. I'm in agreement with stoveliker. You want to minimize the mold spores in your home.

Haven't seen it. I'd put it in the stove, but store it outside, preferably in the sun.

Show Us Your Fuzzy Wood

We had an incredibly wet season year in MA so a lot of my wood. All the ponds are high and my front yard is still wet! Even though all my wood is neatly stacked in the sun/wind and top covered it has some fun fuzzies and different colors this year. It burns just the same, it's just a little more...

Burn it! Just limit the amount of time it's in your house because of the mold.
