Identification Information: Phaeographis oricola is a very distinctive crustose lichen that forms extensive whitish colonies on thebark of hardwood trees and shrubs and can be recognized by its large, circular, erumpent apothecia withone large, brown, muriform spore in each ascus.

ASSESSMENT JUSTIFICATION [criteria: B1ab(i,ii,iii,v)+2ab(i,ii,iii,v)]

Phaeographis oricola is a crustose lichen that occurs on the bark of hardwood trees and shrubs in remnant mature maritime forests in the Carolinian Barrier Islands of the Mid-Atlantic Coastal Plain of eastern North America. Though recently described, it has been documented for more than a decade. Suitable habitat for this species is severely fragmented and has been degraded by anthropogenic forces. It has a limited extent of occurrence (EOO) (2,203 km2) and area of occupancy (AOO) (28 km2), severe fragmentation of the population, a small number of locations (six), and an inferred ongoing decline in EOO, AOO and habitat quality due to continued degradation and fragmentation of suitable habitat, impacts from sea-level rise, coastal erosion, and increased storm intensity. Therefore, it is listed as Endangered under criteria B1ab(i,ii,iii,v)+2ab(i,ii,iii,v).
