Circular black spots 1/4 inch in diameter appear on upper leaf surfaces. Each black spot has a feathery margin and is surrounded by a yellow halo. As the spots enlarge and coalesce, the entire leaf turns yellow and falls from the plant. Purplish or brownish spots and streaks may appear on canes. The picture i saw on the net was the same as yours and it says it is a fungus
