I moved into a rental 2 1/2 years ago that has some kind of 'lantern' tree in the front yard. This year (now) I see obvious signs of distress, maybe disease? There are many dead and dying limbs, lots of green/gray moss throughout, and this year I see a reddish-orange covering on the trunk. Also, the leaves are covered in red splotches but no signs of insects or other critters. It grows on a slightly sloping lawn. I've never watered it, as I'm not tree savvy in general.
