03F9CD41FF9FFF8EFF5CFB4BD458FEE7.taxon	description	Description: — Life form lichenized fungus. Thallus endoperidermal to epiperidermal, thin, effuse; surface whitish or greenish gray, in older specimens pale tan, smooth, occasionally with reddish or orange pigment crystals and areas of pinkish staining; prothallus brown, often as contact lines. Photobiont trentepohlioid alga, endoperidermal; cells (7.8 –) 11.7 (– 18.2) × (5.2 –) 8.3 (– 15.6) µm (n = 39), in short branched chains. Ascomata dispersed, sessile, elongate to furcate, lirellate with ± straight branches and acute tips, (0.4 –) 1.0 (– 1.6) × (0.2 –) 0.3 (– 0.5) mm (n = 60); disk flat, brown, often covered with whitish pruina; margin thick, coated with red or orange pruina. In section ascoma (104 –) 139 (– 208) µm high (n = 6). Excipuloid layer lateral, (26 –) 56 (– 130) µm (n = 12) wide, dark brownish and infused with reddish pigment crystals. Epithecium (13 –) 21 (– 26) µm (n = 8) thick, brownish; hymenium hyaline, yellowish in thick sections, (52 –) 64 (– 91) µm high (n = 10); hypothecium pale brownish, (22 –) 42 (– 104) µm thick (n = 8). Asci abundant, clavate, (39.0 –) 53.3 (– 78.0) × (10.5 –) 17.0 (– 34.0) µm (n = 60), 8 - spored, stipe short or indistinct, tholus (4.0 –) 8.5 (– 15.0) µm thick (n = 10); ascospores narrowly obovate, hyaline, smooth, faintly verrucose and appearing grayish and granular when postmature, macrocephalic, (4 –) 5 - celled, (15.5 –) 22.0 (– 26.0) × (4.0 –) 5.5 (– 8.0) µm (n = 60). Pycnidia frequent, ± globose, partly immersed, (52 –) 80 (– 140) µm in diameter (n = 9), wall brown; conidia bacilliform, mostly straight, hyaline, (4 –) 6.4 (– 9) × ~ 1 µm (n = 10). Chemistry: — Thallus UV –, K –, C –, KC –, PD + golden yellow (psoromic acid); excipular pigment K + magenta then fading; epithecium pigment dissolving in K. AMYLOIDITY: epithecium I + blue, K / I + dark blue; hymenium I + blue or turning red, K / I + dark blue or green in high concentrations; ascus protoplasm I –, K / I + yellow-orange; ascus wall I –, K / I –.
