Wonderful pictorial tour, and the gazebo sure looks like a pleasant addition.
You might want to consider some moderate sized rocks around the base of the gazebo so that you won't return after winter to find skunks or raccoons denning under there. We had that problem with a similar structure years ago at our lake cabin in BC.
It's really not worth the risk to eat wild mushrooms unless you're very sure what they are, Ken. IF they're ok, they can be wonderful but the ones that aren't ok have neurotoxins that can make you crazy or dead pretty quick.
A couple of years ago I found white, firm fungal growths in the soil under my oak trees here. I thought - wouldn't it be wonderful if they were white truffles! The squirrels dig them up and eat them so they should be ok for people . . . well, I sent a sample and pictures to the UF mushroom specialist, a Dr. Kinnebrew if I recall the name and he replied by e-mail DO NOT EAT! POISONOUS. Along with a detailed analysis and scientific names that I have long ago forgotten.
