Type: USA, "America borealis", Mühlenberg (H-ACH 1511 - lectotype, Culberson & Culberson, Bryologist 70: 159, 1970, as holotype).

 

Thallus: loosely adnate, irregular to rosette-forming, to ca. 5 cm diameter. Lobes elongate, 1 - 4 mm wide, weakly wrinkled, usually with scattered, long, marginal cilia. Upper surface pale to dark greenish brown; pseudocyphellae absent. Lower cortex brown to blackish, somewhat wrinkled. Apothecia lateral and marginal, to 3 mm diameter. Spores globose, 4 - 5 / 4 - 5 µm. Pycnidia marginal, protruding, black. Conidia dumbbellshaped, ca. 5 / 1 µm (Ahti & Thell 2011: 106). Photobiont: Trebouxia.

Chemistry:
Race I: Cortex C-, K+ yellow, KC-, PD-; atranorin. Medulla C+ red, K-, KC+ red, PD-, UV-; olivetoric and physodic acids (Ahti & Thell 2011: 106).
Race II: Cortex C-, K+ yellow, KC-, PD-; sometimes atranorin. Medulla C-, K-, KC+ orange to pink, PD-, UV+ bluish white; alectoronic acid, sometimes also alpha-collatolic acid (Ahti & Thell 2011: 106).
