New Be,,,here,,,,this is my 1st year picking hen of woods, and most of the ones I found were past prime picking,, question is,,at the back of the mushroom, there's a hole in the center of each layer, with fine sawdust everywhere, are these spores?? When you see these spores, are you too late??? In picking its prime???
That makes more sense. I've never seen what you've described as sawdust around one. The ones I found which were too old to pick were tough and many had mold on the bottom when you cut them and flipped them over. The holes you see are usually caused by a beetle that lives on them.
I don't have ducks. I don't have rows. I have squirrels. And they're drunk.
