Spring Beauty Rust - Puccinia mariae-wilsoniae
These leaves have been in a jar in my fridge for a couple weeks. I had intended to take some pics of them under the microscope sooner, but didn't have time until yesterday. The orange depressions were empty a couple weeks ago, but are now full of spores. Also, the leaves have turned red.
Initial observation:
''Puccinia mariae-wilsoniae'', commonly known as the spring beauty rust, is a species of rust fungus found in North America. A plant pathogen, it grows on the leaves of the spring beauty flowering plants ''Claytonia caroliniana'' and ''C. virginica''.
Similar species: Pucciniales
