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!

The photo you referred to appears to be in either the genus of Coprinus or Panolus. Many of the Coprinus species are edible for humans (unless they have been drinking alcohol), Panolus species may or may not be psychoactive for humans. Guidebooks list them as poisonous because of this. All this being said it doesn't mean that these particular mushrooms are poisonous to cats. Have a look here http://www.namyco.org/mushroom_poiso...in_dogs_an.php for more info.
