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.

Looks like dried out ink caps maybe.
I could see that. I'm fairly new to Albuquerque, so I'm not entirely sure if they're common here.
