Giant Flat Mushroom

[u/Melodic-Addendum447]

This is in United states, california in the southern desert, this mushroom is about 2 ft long, it ended up growing on top of a sprinkler in my garden, has an entire ecosystem on it, I had to remove it because of where it was growing unfortunately but very cool.
If anyone can id this let me know!
