Mycobank MB 517733

Thallus crustose, corticolous, forming large patches over 5–10 cm wide, pale grey, irregularly fissured, delimited by a dark-brown prothallus line; upper surface flat to depressed-verrucose, smooth; cortex strong, 15–25 µm thick, of densely conglutinated, periclinal hyphae; medulla ca. 200 µm thick, of loose hyphae, filled with many small crystals showing white in polarised light, sometimes including old, overgrown cortical layers. Photobiont trentepohlioid, cells ca. 10 µm in diam. Ascomata frequent, rounded with prominent thalloid margin, 1–3 mm wide, sessile with constricted, wide base, with pale to dark grey-brown, pruinose, flat disc surrounded by a thin, ca. 0.05 mm wide, white proper margin, which is often separated by a split from the thallus-coloured, ca. 0.2 mm wide thalline margin. Hymenium 75–100 µm tall, inspersed with ca. 1–2 µm wide, irregular droplets disappearing in K, I–. Paraphyses ca. 1.2 µm thick, septate, unbranched except near the tip; terminal locules subglobose and to 3 µm thick, not spinulose. Hypothecium yellow-brown, I–. Asci cylindrical with attenuated base, ca. 90 x 10 µm. Ascospores hyaline, 8/ascus, uniseriate, submuriform, with rounded lumina, I+ dark blue-violet, 10–15 x 7 µm, with 4 x 1–2 locules, halonate. Pycnidia not seen. Secondary chemistry: thallus K+ orange, C–, KC–, UV–. Secondary metabolites: constictic acid (TLC).
