Abstract

Pyrenopeziza plantaginis is reported from leaves of Plantago lanceolata from remnant native prairie sites in Benton Co., Oregon which harbor the endangered Taylor's checkerspot. The butterfly uses P. lanceolata as a pre-diapause larval host. The fungus is associated with a leaf blight of P. lanceolata and may impair restoration of populations of Taylor's checkerspot.
