I don't mean to sound like a jerk. But I get tired of people passing on information when they don't REALLY take the time to learn themselves. I am not saying YOU Latt. But alot of the info you passed on I can tell has been from reading.
Things are different in the different parts of the states. What works in one area may not work in another. As far as the live fruit trees, I have seen much bigger flushes under dying, and dead. They pretty much grow anywhere, even under pines which may be a good spot for you to look TNhunter. I have found good flushes in White Pine in a few different states. I don't like to share too much info anymore on open forums since it has gotten very bad in the areas I pick, and gets worse every year. Every little bit of info given takes the edge away from you. It used to be people would wander the woods hoping to find a few morels. Now adays with the use of the internet people go out and hunt target areas. Most of these have been listed already, but some of the trees will produce alot better if alive rather than dying or dead. Also alot of them haven't been mentioned, and are very good producers.
If you are deadset on finding some this year TNhunter. My suggestion would be to hunt the later producing trees mainly, such as Ash and Tulip, but I also wouldn't pass up the others if spotted in route. Hunt the deep hollows on north facing hills. Also in Pine Groves or breaks on the groves since they are shaded more and the ground temps have warmed later and may have yet gotten too warm. Here you may find SOME yellows still edible. I will tell you this though. You are going to find many, many, more spoiled. But will give you an idea of what to look for next year. Pay close attention to the surroundings when you do make a find. Store this in your head, then put all the pieces together to find the common factors.
It's pretty much like hunting Ginseng. Find out what habitat they prefer and you have much of the puzzle solved.
One last thing. If you make a find near a certain type of tree, don't assume that it has fruited the mushrooms. Look around well and try to figure things out.
I hope this helps you a bit TNhunter, and really hope that you do well next season.
