rYou should remove the branches with the fungus and dispose of them separately from other yard waste. Your tree will need to be sprayed with a fungicide copper spray....usually three times with a week in between. Check with a local garden center to see which sprays work best in your area.
Be sure to wipe your pruners with alcohol so you don't spread it.
