Tree identification. Suitable for growing shitake, reishi and/turkey tails?

I just picked up these two logs by the road that have been cut 2 weeks ago. Can anyone identify them? There is many, many pieces like this in the bushes.

If you have some time, I would take some wood shavings from the log and do a trial run. If you have innoculated dowels around, it would be a low cost experiment. I would also check the ground around the fell site for identifyable seeds or nut shells.

Also, any leaves from the fell site would go a long way to help identify it.
