andrewcannon's Identifications

On Erythronium sp. (americanum definitely present, but E. album may also be present at this site too). Not yet producing spores, but many individuals in this extensive population show this leaf discoloration and curling. Could this be Uromyces erythronii?

PNHP Botanist Rachel Goad @rachgo noticed something funny on this trout lily leaf, and having noticed a lot of rusts that day she thought it might be something fungal, but we were already lagging behind the group so I grabbed the leaf and threw it in my tacklebox, unfortunately without taking a picture of it fresh. I showed it to a colleague and they figured it was insect damage. A week later, after attending a talk by Sam Bucciarelli @that_hippie_chick on rust and smut fungi in which she mentioned the trout lily smut fungus, I dug that leaf out of the trash, cracked it open and revealed the black spores!
