Last week I was checking on one of my compost bins and noticed that there was a group of these mushrooms growing on a clump of composting leaves. Given the heat, I'm surprised to see them growing in the bin. Any help identifying them is most appreciated.

I took a break from work around 11AM which is strong the time that I found them.
I'm not sure if they dried up in the heat of the day, unfortunately. I put them back into the compost bin because I want as much fungal activity as possible. This particular bin is one of those enclosed, rollable units. It's nice and humid inside.
