Not sure what is causing these?
I live in the Layhill area of Silver Spring. I have noticed several of these 'mud mound' appearing in my yard, and near the foundation of my house. They are typically between the size of a tennis ball and a softball. The perimeter of my house was treated for termites about 3 - 4 years ago, and the inspector said that these mounds are not caused by termites. Can you please tell me what might cause these?
We viewed your photo but it is out of focus. Please resubmit the photo in focus and we would be happy to look at it again. It is possible it may be a type of mushroom (fungi) but we cannot say for sure.
