This is undoubtedly inspired by the weekend's yard work, which involved pulling out the shrooms on the lawn so James could mow. We had half a wheelbarrow full, all of 'em inedible and many of them in various stages of decomposition.
I have a stomach like cast iron under most circumstances--nothing short of actual food poisoning lays me low--but I tell ya, pullin' up half-rotted mushrooms for an hour had a definite impact. (And then of course I do a pretty painting of pretty mushrooms. Typical.)
One interesting thing--while looking up mushroom species for the painting, I found out that the pretty little things I always thought were puffballs were actually oak leaf galls. Which isn't a fungus--it's a tissue reaction to mites or parasitic wasps--and so is not includeable.
Here's one of the few good photos I could find of the kind I remember:
