Got a friend at work whose husband is a mushroom guy. I mentioned to her that I came across this pretty big mushroom growing up a tree. I gave her the town and and the road and thought he might get back and ask for more particulars. But no, BD is a bit crazy (wife's words, not mine). He actually headed out and found it all on his own. It is a Northern Tooth Polypore and is a non-edible.
That same afternoon, he harvested some Chicken of the Woods in Limerick. He knows mushrooms. He has to. Why? He sells them to local restaurants in Portland. He's been doing it for the last few years. Here's another example of something we stumble upon, and it becomes a passion.
