Any Mushroom Experts Out There?

By Vickilane

These guys showed up in my greenhouse and I'd very much like to now what they are.

My little Golden Nature Guide to Non-Flowering Plants leads me to think they could be Meadow Mushrooms. But I don't know.

And no way would I be tempted to try one even if some expert out there tells me they're edible,

I wish I knew more though. The only fungi I trust myself to identify are the shitakes and oysters we have grown and the occasional rare find of a morel.  I know there are probably many edible mushrooms in our woods but I need to see an expert identify, cook, and eat one before I'm ready to try.  And even then, I'll wait a day or two to make sure the expert survived.
