Oak tree fungus

Post by Liasings » Sat Jul 15, 2017 6:17 pm

Does anyone have any idea if this fungus is something to be panicking about? There has been no weedeater damage to the trunk, despite the freakishly straight topline of this growth. It is in a mulched bed, but the mulch is less than an inch. The tree is a replacement for a prior 40+-year-old oak that was chopped indiscriminately by the power company, resulting in danger to the house. This oak has been in place for 10 years.
Today, I shot the fungus with the hose, and it peeled off and left the bark looking untouched. That's great, but this tree is an increasingly vital source of shade and I'm concerned that the fungus may be an outward indicator of a problem.
I included a pic of the leaves in case they contain a clue. :?:
