I don't know a lot about mushrooms. (In the whole world, perhaps six or seven people do, and most of those are professors long-emeriti.) I don't like eating them, either. So I consider irrelevant the inevitable, unimaginative question, "Is it poisonous?"
Maybe. Maybe your shoe is poisonous if you eat it. Just love mushrooms for being mushrooms.
My best guess for this first batch is Fairy Ring Mushrooms, Marasmius oreades. Considered by many a lawn pest. Edible? Maybe.
More of the same, I think, but older and rangier. They leap upon each other like victorious baseball players (World Series footage is on TV as I type).
No clue, although they look rather ordinary. I flipped through three mushroom field guides three times and saw nothing like them. Edible? Maybe!
Here, I'm guessing, a Lepiota of some sort. Edible? Perhaps. Or not. Here's what McKenny and Stuntz (1996: 79) say of our regional Lepiotas: "The Pacific Northwest has a variety of small- to medium-sized species of Lepiota. Identification of species is difficult, and certain ones, such as Lepiota clypeolaria and L. rubrotincta, are reported as poisonous, the latter causing gastrointestinal upset. In addition, some species, such as Lepiota helveola, are known to be deadly. Avoid all of them." So there.
Tiny buttons, perhaps deadly, perhaps gastrointestinally irritating (if you eat them--why you would, well, I have no idea) of same Lepiota sp. (unless I am wrong, which is entirely possible, see paragraph 2). The shiny silver thing in the middle is a Canadian four-cent piece. A week ago it was called a nickel and was worth five cents. At least the mushrooms are getting bigger.
And then this. Like a herd of bison, massive, majestic boletes take over the area beneath a Douglas Fir. The tree association leads me to believe them to be either Suillus caerulescens (first guess) or S. lakei.
Large ones encourage and comfort younger ones. "Don't worry. Probably no one will eat you, because although you may be edible, you may also cause gastrointestinal upset."
