Mushroom Bonanza

I have lived here for 15 years and I have never seen a gathering of mushrooms like this anywhere in the yard. These sprang up in just the past ten days. Usually mushrooms are associated with damp conditions but we are in the middle of a drought and everything is very dry. There are a number of these bunches of mushrooms on the path on one side of the yard. Thankfully our Great Dane doesn't seem too interested in these plants as I don't know if they are toxic.
The other picture shows a closeup of the biggest mushroom bunch. They almost look like a stack of pancakes to which you might want to add some syrup.
