Thanks to Master Gardener Sue Schneck for these wonderful photos of Cedar Apple Rust taken with her Galaxy S5 phone camera!  This disease requires two separate living host plants. In Sue's garden the host and alternate host were juniper and crabapple trees.  When Sue removed the juniper from her garden, the cedar apple rust disease disappeared.
