    It could possibly be a woolly aphid? It's hard to be sure without a closer pic :)

    Did you lift the bark to find the white substance? Or did it break away of its own accord?

    That's fairly extensive decay you have there. Whether it will harm the tree or not, hard to say. If it is just confined to the heartwood (which is dead anyway) it won't hurt, but if it also affects the live sapwood, then the tree is on the way out.

    In other words the white stuff is a fungal growth.

    is there any remedy for this? Can the tree be saved if it is under any harm at all?
