I was pretty sure of the Epilobium it was growing on

I believe there were uninfected plants growing right beside the infected ones. Aren’t all the Berberis (at least in those parts) woody shrubs or subshrubs?

There’s Puccinia pulverulenta, IF’s preferred name for Aecidium epilobii and Puccinia epilobii-tetragoni. The following page:

http://www.fungalpunknature.co.uk/...

asserts that the “main ID feature is the white fringed upper edge to each cup which seperates [sic] this from similar species.” I think I see that represented here. How do you know this isn’t Berberis it’s growing on? It looks just like the picture in my book… Bear in mind, my first botany class ever doesn’t begin until 9AM tomorrow morning.
