Twenty-eight lichens are reported new to Crawford County, Pennsylvania, providing the most recent data on lichen diversity in the county. Previously, 20 lichens were collected in the early 1900s, of which three were confirmed in this study. The lichens identified at all sampling sites are Candelariella efflorescens, Cladonia ochrochlora, Flavoparmelia caperata, Lepraria finkii, Physcia millegrana, Phaeophyscia pusilloides and Phaeophyscia rubropulchra, all of which are common in northeastern North America.
