Melampsora caprearum is a fungal pathogen which causes galls on willows (Salix species). Also known as a rust fungus, it was first described by Felix von Thümen in 1879.

Description

M. caprearum distorts the blades and veins of willow leaves, causing irregular spots with yellow-orange uredinia (which produce a powdery mass of spores). The rust has been found on eared willow (Salix aurita), goat willow (S. caprea), grey willow (S. cinerea) and their hybrids.[1][2]

Distribution

Has been recorded from Belgium (photo), Finland, Great Britain (common) and Poland.[1][2][3]
