Strange white spots on a poplar tree

[anansi]

Hello, everyone.

I have what I am told is a poplar tree on my property that has been dead for some time. This tree is about 50 feet tall.

Recently, white spots have appeared on the trunk and they are growing in size and length. At their current growth rate, the tree may be completely white by the end of the month.

Can someone tell me what might be happening to this tree?

Should I cut this tree down?

Do I need to worry about this disease affecting the other trees in my landscape?

Thanks.

Sounds like a common fungus that lives/feeds on dead wood. The tree should probably be cut down or it will blow down eventually.

If its in the yard it should probably come down because its a hazzard. If its in the woods, leave it. It'll provide good habitat for wildlife.
