I didn’t collect any…

I wasn’t even sure it was a fungus until I got home and looked it up. It was on some kind of wild rose, pretty rampant throughout the campgrounds at Pinnacles.

I don’t think there is much hope to identify this without microscopy, I understand even the experts can’t identify most Phragmidium on roses…

If you collect it, wait for it to go black with telia…

And is this an ornamental or wild rose?
