There is little that can be done for the tree and it should be removed. The fungi is not superficial on the outside of the tree and is rotting the tree from the inside out. It is not a disease killing the tree but a really just saprophytic fungi living a dead bark and wood.The interior wood is rotting and becoming soft and losing its strength. This particular fungi is the White bracket fungi (Irpex lacteus). The initial injury was probably the two sever winters in 2013 and 2014 which injured the wood and bark of the tree.
