Notes:

A group of Mugwort plants along side of an arable field with the following hypophyllous infections: Erysiphe artemisiae, Cercospora state of Mycovellosiella ferruginea and telia of Puccinia tanaceti on live and fading leaves.

Telia: hypophyllous, very dark brown, cushion-shaped, under the tomentum (occasionally peeping out at the edge of the leaf). Under a hand lens they look a bit like Cardamom seeds!
