What is causing white fungus to grow on my Amur chokecherry tree?

Asked August 28, 2014, 10:17 AM EDT

My prunus Maackii, common name Amur chokecherry, has white fungus growth on the trunk, and there are large areas in the trunk where the bark is peeling and seems to be chewed. I've attached photos.

The white growths on the trunk of the tree appear to be shelf mushrooms. Mushrooms are a sign of rotted or rotting wood. The peeling bark is caused by decay, or decay is making it easy for animals to chew the bark.

It is time to do a hazard assessment. If the tree comes down during a storm, will anything be harmed? If people or property would be harmed, it would be best to take it down in a controlled manner. For more information, click on this link for a publication on Tree Risk Assessment and Management.
