These are photos of some mushrooms popping up in our yard this spring.
This bright yellow mushroom was growing next to a phalaenopsis orchid. It's poisonous - a Lemon-yellow Lepiota.
Pink Mycena or coprinus is the one that looks like a gray umbrella (I'm guessing).
Fairy ring mushroom (Marasmius oreades) or lawn mower's mushroom (Psathyrella foenisecii) Both edible with the fairy ring listed as good but may be confused with two other poisonous mushrooms.
I'm not a mycologist so these are just guesses. The yellow one had an especially beautiful bright color the only one that was easily identifiable.
