Observation 133078: Puccinia monoica Arthur
When: 2013-05-05
No herbarium specimen

Notes: This Rust fungus was prominent on many plants of Arabis sp. At least 2 species were involved.
The fungus causes the flowers to abort but the stem glows with a strong yellow color which attracts insects, as does the floral scent it produces.
