Dave,
Thanks again for your response. Very helpful. I found a few others that I cut open in the fall (pictures added) to find the darkening of the pores, which I believe is a good indicator that you've found edible (or even King) Bolete's. I'll spend more time this fall finding more and picking them to properly identify them. They are a mushroom that appears to grow in this area and I would love to add them to my repertoire of edible mushrooms as I understand they're quite delicious.
If you can spare a moment, perhaps you could also weigh in on these two pictures and tell me what you think. Again, a mushroom I'm very keen to get to know, so your knowledge and time are greatly appreciated.
