white fungus

Question

I have a maple tree that is losing bark at the base. One area is black, another area has white nasty looking stuff and goes from ground to 18″ up the tree. All leaves have turned yellow. Should I have the tree cut down before it infects other trees?

Answer 1

This is likely a canker or fungus disease.
