Crown Rust - Puccinia coronata
Puccinia coronata is a rust fungus with orange aecia which galls the leaf blade and petioles of Buckthorn and Alder Buckthorn causing them to become twisted and distorted.
May be found where Buckthorn and Alder Buckthorn are in leaf.
Late spring to early autumn.
Widespread and fairly frequent in Britain.
Thought to be fairly frequent in Leicestershire and Rutland in areas where the host species are present.
