Mycology

Another one nearby:

I noticed these guys while walking my dog around the apartment. At first, I thought they were roots for the bushes they were in between, but then my husky stepped on one, crushing it and showing me it was some kind of mushroom. I don't know shit about mushrooms, but they do look unlike anything I've seen growing wild (especially in a city), and the only thing they look close to that I do know is a truffle. But surely they aren't truffles? In an apartment complex?
