Killing fungus

Question

I have just noticed brown jelly fungus on my red oak tree. It is at the base. I am wondering if I can treat this or do I need to call a professional arborist. Pic attached.

The jelly fungus itself is not harmful to your tree, but it is a sign that the tree is sick or dying. These fungi only begin to grow once a tree is rotting due to other health problems. As this article explains, it's best to consult an arborist:
