It's a very big tree and it has the helicopter things.
It has thorn like things on the sticks. the leaves are riley grooved.
the leaves have hols in them, black spots, and some bugs.
It looks like a young tree, it looks like it has bug eating, and it has brown spots.
Yellow pores mean it is L. sulphureus rather than another member of the genus (whitish pores)
Mustard-yellow polypore (look at the flesh of the cut section)
Japanese umbrella inky
Common gray disc
Bean like seed pods.It also has white man made swirly things with hols in it. I found it at the edge of a park forest.
