It is unlikely that that was a rust that swelled the bark or
caused the witches' broom.

Hawthorn (Crataegus) are not involved in ceder apple rust.
They ARE susceptible to quince rust (Gymnosporangium sp.)
but rusts affect leaves, not stems, and don't do witches'
brooms.

BTW, the Ortho Home Gardener's Problem Solver lists J.
chinensis 'Foemina' and 'Keteleeri' and var. sargentii as
"resistant" to cedar apple rust. J. scopularum and
varieties are "particularly susceptible" to cedar apple rust.
