Hello, I live in North Jersey and I was coming home and noticed this very large growth on an oak tree outside in my front yard. From far away I thought it was a big beehive. A closer look showed me that it was actually some kind of fungus. It's about 5 feet up on the tree from the gound. Measuring about 13.5 inches high and 15 inches wide. There is also a smaller growth about a foot higher up on the tree. Can someone please help me identify these and are they toxic? I have attached the pictures I took at night to help.
