NS3879 : Rust fungus on rose bud
taken 12 years ago, near to Alexandria, West Dunbartonshire, Scotland

Rust fungus on rose bud
The rose plant is growing beside a path from Millburn to Overton Road; the path is shown, in another season, in NS3879 : Path to Vale of Leven Cemetery. The orange mass erupting through the base of the flower bud is a fungus of the genus Phragmidium. For the complex life-cycle of the rust fungi, see NS3679 : Gall on nettle.
