All About Quince Rust

On a recent DeKorte nature walk, botany whiz Edith Wallace noticed an unfamiliar fungus on the Amelanchier canadensis (Serviceberry) by the Butterfly Garden.  She consulted Rich Buckley, manager of the Rutgers Plant Diagnostic Lab, for an ID.

Rich says the photo looks like "Quince rust, Gymnosporangium clavipes.  Quince rust is easy to ID, as opposed to hawthorne rust or cedar apple rust, because it makes the aecia on fruit and green stems instead of the leaves."  (Thanks, Edith and Rich!)
