The fungus among us!

I have no idea what these are. I have never learnt much about fungi in this country (except morels!) . These are growing at the base of a hackberry in our yard. They won't last long. You can see that several are already beginning to dehisce and spread their spores.
Have to go now . I hope everyone is having a great Sunday we had about two inches of rain last night, thunder and lightning but nothing severe.
Thank you so much for all the stars and comments on the peony.
