Pear rust Gymnosporangium sabinae
Image created with Bresser Biolux NV microscope and compact camera, 3 images were stacked using photoshop to create a wider depth of field.
Pear rust is a Biotroph fungus which cannot survive on dead plant matter so keeps its host alive. It attacks Pears during the summer but moves to Juniper leaves during the winter as Pears shed their leaves. It needs two hosts in order to survive because of this.
