Descriptions
Thallus in patches or bands, 3-8(-20) cm diam., pale olivaceous-grey to grey-white, matt or shining, irregularly wrinkled-plicate or ridged, irregularly cracked to ± areolate. Apothecia sessile, constricted at base 0.5-2.5 mm diam., ± hemispherical at maturity, blister-like at first becoming erose-white-sorediate, disc subconcave to plane, often fissured,pale buff to dark brown or grey, densely white-pruinose, pruina granular, margins thick, fissured, eroding, roughened-granular, -like, covered with thallus at first then white-sorediate. Asci clavate, with well-developed apical tholus, 8-spored (rarely 6-spored). Ascospores uniseriate, oval-ellipsoid, pointed at one end, rounded at other, occasionally apiculate at one end, 43.5-74 × 26.1-38.8 µm. Chemistry: TLC 3 unidentified compounds (brown-purple or greyish).
Thallus in irregular, continuous patches 2-6(-10) cm diam., olive-green to pale grey-green or fawnish, wrinkled-verrucose or shallow papillate, areolate-cracked, shining or matt. Fertile verrucae 0.5-1.5 mm diam., to 1.2 mm tall, sessile, rounded, white-sorediate at first, margins concolorous with thallus, thick, wrinkled-striate or ± exfoliating, white-pulverulent.
