Rust (?) on rose

A gall-type growth on a domestic rose bush in a garden. I'm not sure whether this was a bud or a leaf. Green, bulbous base, and curled, yellow outgrowth with flaky outgrowth. Could be a rust fungus, since it looks similar to the picture in http://www.extension.umn.edu/projects/yardandgarden/YGLNews/images2/Jun1...
