Mushrooms on a dead tree

This hackberry tree fell down about a year ago it was blown down by strong wind while the ground was very wet.

My husband cut part of the trunk up for me to use as plant stands outdoors. They work pretty well for this.

These mushrooms look like oyster mushrooms but I am not sure for sure if that is what they are. The tree trunk was taken over by them and this did not happen until the tree fell down.

I thought the mushrooms made a nice picture.

The fungus is among us.
