Final diagnosis


Rouille hétéroïque

A few large orange to necrotic spots are visible on this leaf.  <b> <i> Puccinia opizii </i> </b>
On the upper surface of the leaf blade, we note that the orange spots seem to be made up of several juxtaposed orange-yellow structures.  Indeed, tiny cups are recognizable on the underside of the limbus.  They are the aecidioles of the fungus.  <b> <i> Puccinia opizii </i> </b>
