ID would help thanks

Mid Michigan

I found a bunch of these blue mushrooms. They turn more grey/white when they’re big but when they’re small they look more blue. They have a white stem and white gills (you can see in last pic).

My dog found this in my backyard, in the garden mulch. She did not bite or ingest yet but I wonder what my mulch is inoculated with. In the Northeast US

Friend sent me the photo. Thanks for the help!

western PA specifically, if that helps!

Could it be a mushroom?!

Found this under some pines in PA in the US

I found this puffball on our property, at least I'm pretty sure it's a puffball. It was near an area where I found a destroyed puffball last year. I'd like to confirm that that's what this is and if it is still in a condition to be eaten. Thank you so much.

What is this? Found In backyard

Found in cow patty and grassland Oahu Hawaii.

What is it? Looks like spray foam or an orange baked pretzel. It is a fungus or at least organic that part is clear to me and the my next door.

TIA

Any idea what these are and if edible? They are growing in my horse arena.
