Joe Boggs reported that cedar quince rust is beginning to show up on hawthorn fruits in southern Ohio. Fruits are becoming covered with orangish-pink spore horns, though these tendrils are not at full size yet. Over time, there will be a stunting and death of fruits and swelling and distortion of twigs, with unsightly spherical cankers developing on stems that can last more than one year. The spores produced on the haw fruits will not re-infect hawthorns or other rosaceous plants. They will only re-infect junipers, starting now or soon further north, and for the rest of the growing season.
