- Only infects apples and cedar (Juniperus virginiana), and requires both hosts to complete its life cycle
- Infected fruit and leaves develop yellow-orange lesions on the surface and in some varieties spore-producing tufts also develop
- Lesions are raised and can crack as the fruit enlarges
- Stems may develop a slight swelling
- Galls with finger-like projections are produced on cedar hosts
- Spread with infected plant material or by wind dispersal
