I agree, looks like a mulberry. Leaves on small trees and new branches are particularly likely to be lobed in mulberry, while older branches tend to produce leaves without lobes.

My thought would be to get flat PVC end caps. These could be attached to the wood with screws, and the pipe attached to the caps with PVC cement.
I agree with the other comment -- looks like maybe insect damage or (fungal?) infection, but I'm really not sure. You might try looking through Sue Bottom's Orchid Disease Guide (PDF), if you haven't already.
