Thallus epiphloeodal, in irregular patches, 1-5 cm diam., greyish-white to pale olive-cinerascent, continuous, irregularly minutely cracked, somewhat coriaceous, minutely maculate (×10 lens), not delimited at margins. Perithecia semi- emergent to emergent, scattered, solitary, rarely 2-confluent, 0.8-1.5 mm diam., applanate to hemispherical, black, shining. Ostiole large, 0.1 mm diam., with a distinct black rim, apical to ± marginal, pycnidia common, minute, black, punctiform. Ascospores lemon-shaped, 4-locular, middle two locules larger, often ± angular, 27-32(-36) × 12-15.3 µm. Chemistry: Cortex K+ dingy brown. UV+ pink after charring.
