Looking for some help from some arborists. Have a Hackberry tree that is 30 to 40 feet tall and has some "foam" coming out of the trunk. The leaves are of a lighter green color than they should be. Also have a Hackberry that is planted about 30 feet away and do not want it to become "infected" with the same problem. Have attached a picture of the problem and was wondering if there was any input on this.
Hort grad here. It's definitely a fungal growth of some sort, the only way you would have that type of fungus is if there is decaying wood in the tree somewhere, ie rot. I'd definitely have an arborist come out and look at it, my guess is it will need to be cut down before it rots so far it falls down. As far as it transferring to the other tree you have nothing to worry about unless the other tree is rotten/decaying as well.
Now that MBB is back, do we still have to pretend that WBB matters?
