Can anyone help me identify these mushrooms? Found them in a patch of dirt in my backyard area next to a stump. I live in Los Angeles. They look darker than they did yesterday, possibly because they're wet (it's been raining hard all morning), but I'm also pretty sure they're dead/rotting. They were either being crushed by or growing around a ladder that I moved, that I'm sure wasn't great for them.

The whole thing looks gross and decomposing, so I'm pretty sure they're old and rotting. Wasn't able to get a spore print either, though that's something I had never done before so maybe I'm just doing it wrong. If they're all decomposing, should I remove them all to give a chance for new fruiting bodies to spring up? I doubt the rains will last here much longer so I want to allow for new mushrooms to pop up if that's possible.
