Growths under ash trees

Question

Some ash trees in the Iowa area have growths on the ground under the ash trees, apparent from the roots near the surface. They initially appear to be mushroom like, but then turn into a dark brown ugly semi-liquid. What are they and what should be done with them?

Answer 1

Without a photo I couldn't be completely sure, but it sounds like tar cap mushrooms. Once the area dries up significantly, they will go away on their own.
