Can someone please help I can find nothing to help me identify this mess. We noticed that our Japanese Magnolia is dying. It's branches are covered in black. The leaves are weighted down with a sicky substance that is actually dripping into the grass and killing it too. On the branches there are tiny (about 1-2 centimeters) little yellow pod like things. Round with a raised square, it looks like some type of bug may be incubating inside...The tree out front looks like it is on it's last leg, and we just noticed that it has moved to the southern Magnolia in the back.
