I found this truffle like growth in a bib faucet vault in my garden. It is very dense feeling. It feels heavy, unlike a normal mushroom. Is it a truffle? What else could it be?
Washington County Oregon mycology
This is Scleroderma citrina, poisonous. It is not really a truffle, but is related to puffballs.
Thank you very much. I was so excited to see something so different. I now have a name to research.
