Type of tree parasite
We are not sure, possibly some type of ? Ash? I have included some pictures of the other tree with some smaller infestations, in the same area as the tree with the bigger blob in it. It is just starting to leaf out.
It is a woody fungus I think, looks similar to Chaga that grows on birch trees except it has some sappy areas.
That definitely looks like what our trees have! Thank you so much for your help! Jo Ann
