Descriptions
Thallus olive greenish with a yellowish greyish tinge, continuous, or minutely cracked, in places noticeably areolate to diffract, smooth to minutely roughened-granular, matt or shining, not delimited at margins by a black prothallus, in irregular patches or bands, 0.5-5 cm diam., corticolous (bark or twigs). Apothecia prominent, scattered, solitary to 1-3-confluent, sessile, rounded to ± irregular through mutual pressure, 0.5-3.0 mm diam., concave at first becoming plane or convex, disc black or dark olivaceous brown-black, matt, epruinose, margins prominent, ± persistent, black, slightly raised, entire to flexuose, proper exciple below fruit, thick, carbonised. Epithecium 20-25 µm thick, olive green or bluish. Hymenium 250-360 µm thick, colourless. Hypothecium 200-250 µm thick, black or brown-black. Paraphyses simple, 2 µm thick, conglutinate, not, or only slightly thickened at apices. Ascospores broadly ellipsoid or oval, apices pointed at one end or both ends rounded, slightly constricted at septum, locules ± equal, 10-13(-18) × (17-)20-33(-38) µm.
Thallus olive greenish or greenish-yellow to creamish-buff, ± areolate, wrinkled, verrucose or lacking. Apothecia sessile, scattered, few to many, 0.5-2.0 mm diam., disc black, smooth, concave at first, becoming roughened, convex and immarginate with age, margins persistent, thick, concolorous with disc, thinner and sometimes occluded at maturity. Epithecium blue-black, 8-22 µm thick. Hymenium colourless 80-110 µm tall. Paraphyses discrete 2-2.5 µm thick, apices blue-black, capitate. Hypothecium blue-black or green-black, dense, thick. Ascospores 20-34 × 10-15(-18) µm, straight, apices pointed or rounded.
