Found these wierd bumps on a piece of wood from a dead tree that was cut for firewood. The wood has been laying on the ground since summer. Not sure what type of tree it was. Trying to figure out what it is. Location was Dowagiac, Michigan (Cass County).

Hello,

This is the fruiting body of a fungal rot that is breaking down the wood. This is a natural way for wood to be recycled by nature. Keeping wood you want to use dry can reduce the occurrence of the wood fungi from appearing on the surface. Wood laying on the ground will absorb enough moisture to allow the fungi to break down the wood.

Here is a brief article with firewood storage details, should you need it-
