theres a fungus among us! Ive seen it growing on my logs before. Seems to prefer certain species. One reason i always liked making firewood in the cold. No bugs or micro organisms/fungus etc. to attach to it. Ive cut logs and within a day or two the sapwood has something growing on it!
My poplar all looks like that this year, except white, and more of it. Even the stuff that was cut last year and was under cover.
Thanks for the responses guys, even the funny ones . They are sitting stacked in a covered and relatively aerated place. Just wanted to make sure they weren't starting to rot on me. It's getting pretty cold up here in Canada so i assume it wont live for very long. Unfortunately, skunks still do, those poor dogs of mine got a good taste of them.
