Hello, I discovered a mushroom growing in one of my cucumber pots. It's about a day old and 3 inches tall. Got the potting soil from walmart and it's been incredibly rainy the last few weeks. I was directed to this service by my local librarian. She said you might be able to help identify it. Thanks!

This looks like one of the ink cap mushrooms. The rain that we have been getting has contributed to the growth of lots of fungi. If you do not like it, pull it up. vw
