Descriptions
Thallus white or greenish-white or pale green-grey, closely attached, spreading in rounded patches, to 8 (rarely to 20) cm diam., corticolous. Upper surface rough, chalky, minutely areolate-cracked, areolae angular or plane, 0.2-0.3 mm diam., separated by narrow cracks. Apothecia lecideine, sessile, constricted at base, 0.5-1 mm diam., crowded in groups or dispersed, disc concave at first, becoming plane or subconvex with age, white-pruinose at first, becoming brownish-grey or bluish-pruinose when mature, often gyrose centrally, proper margin distinct, white-pruinose to blackish, entire or crenulate, or distorted by mutual pressure. Hymenium 140-160 µm tall, blackish above, pale brownish below. Asci clavate, rounded at apices, walls thickened, 85-90 × 13-15 µm. Ascospores 3-4-seriate, acicular, apices rounded, straight or slightly curved, 11-13-septate, 36-45 × 3 µm. Chemistry: Schizopeltic acid and an unidentified (UV+ violet) compound.
Thallus pale yellowish-green to whitish-green, closely attached, and spreading in rounded patches, to 8 cm diam., corticolous. Upper surface continuous, minutely granular-verrucose, matt. Apothecia lecideine, sessile, constricted at base, dispersed or crowded in groups, distorted by mutual pressure, rounded to subirregular, 1-1.5 mm diam., disc plane to convex, densely white-pruinose becoming pinkish-white, black and shining beneath pruina, margin dark brown or black, thin, entire, often crenulate-contorted. Hymenium 160-180 µm tall, dark brown at epithecium, colourless below. Hypothecium brown-black. Asci crowded, clavate, apices rounded. Ascospores 3-4-seriate, 7-septate, curved, 38-45 × 3 µm. Chemistry: Lepraric and schizopeltic acids and 2 unidentified compounds (UV+ violet.)
