We have some sort of spiney orange (fungus?) on our Juneberries. For the last few years the bush hasn't produced many berries. This year there are lots of berries but all of the larger ones are covered with orange powdery spines. The orange colored powder comes off when the berries are disturbed leaving behind whitish spinelike tubes. The leaves also have small brown splotches all around the outer part of them. I don't know if this is related or not to the spiney fruit.
Can anyone tell me what this condition is called and what if anything I can do to save the bush? I would also like to know if it will spread to other types of fruit and if so should I remove the bush? Thanks
