I counted the growth rings of the tree -- and it's well more than 100 years just to where the little mushroom was growing! The rings are so close together because it grew in a mature forest. That is an old-growth forest and tree, for sure. The rings are so much farther apart these days, in the timber harvests from replanted forests.
I'll let you know about the moss! Thanks for venturing an answer!
