Infection
A rust fungus on one of my current bushes, Ribes sanguineum. I had noticed numerous dark pink/red spots on the leaves, but this 20-shot focus-stacked image shows the petiole of a leaf affected, with the infection progressing down into the leaf itself. An unusual pattern is shown by the orange spots - these are the fruiting bodies of the fungus that have erupted to produce spores.
For Macro Mondays theme 'Unusual Patterns'.
No rust fungus was harmed in the making of this photograph.
