Mushroom in a Maple

Mushroom in a Maple

While walking around the property this weekend, I noticed this in (what I think is) an ancient Sugar Maple in the front yard.

Since we moved here, nearly 15 years ago, I thought this tree was not long for this world, but it leafs out every year and offers a nice fall color display.

It's in a spot that even if it comes down, does not endanger the house, or any part of the property, so I've left it alone to watch what happens.

Thought this was kinda cool, so offer it here for your enjoyment.
