Good afternoon, A local nursery referred me to your office. Attached are pictures of some type of fungus that is growing in our yard. I have not been able to identify this on the web and so I am turning to you for help. The issue has been going on for maybe 4-5 years and the number of these fungi is increasing. Initially I thought they were only in the yard, but this morning I discovered them in a flowerbed next to the yard where they grow. Size is about that of a tennis ball or maybe a little bigger. They come up above the ground about the height of a tennis ball. They then open and span out. They have a deep hard stem/root that is maybe 4-5 inches. We tried digging them out for a few years but it hasn't gotten rid of them and the number is increasing. It is only on one side of my yard that abuts to our driveway and the garage. I am not aware of any of my neighbors having this problem. We do live down hill on a cul de sac in Jefferson, MD and the subdivision was built on farm land. Any assistance you can give is greatly appreciated.
