Finally, enough rain has fallen to goad the Amanita muscaria mycelia into producing their fruiting bodies, i.e., their mushrooms. This variable and very widespread species here associates with paper birch and grows very large (sometimes almost dinner-plate) and very red. In other localities it is smaller, and more yellow or orange.
It's hard to find a fairy-perfect, intact one; they get nibbled by squirrels and grazed by slugs, despite being toxic to some degree. What I wrote about them last year, a bit earlier in the season.
