I just had my backyard redone and I am attempting to do some gardening (I live in the SF Bay Area). I hope to be able to get some help in this group. I had a small patch of grass put down in my cat enclosure for the cats to go out and play in. If you have cats, you know that they chew on grass. A few days ago several mushrooms sprung up in the grass. I am afraid these may be poisonous and obviously a danger for the cats. I have done some research on the web on mushrooms in new sod and found a lot of info, but nowhere it states whether these mushrooms are poisonous or not. They look like the ones in the picture he

I wonder if anyone in this group may know. Thank you in advance!

Typically animals know not to eat fungi and poisonous plants but still
I would remove those mushrooms so they are not accidently ingested as
cats tend to play with things they find and then may ingest bits as
they clean themselves. The parts you see are only the fruiting
bodies, the vast majority of mushrooms are underground, their mycilian
are the largest living organisms on the planet, so you cannot
eradicate them. This may help you identify them:
