| Thallus endophloeodal to epiphloeodal, to c. 300 µm thick, dark olive-green to olive-brown or pale yellowish brown, dull to waxy, smooth, continuous to slightly verrucose, non-rimose. True cortex ±continuous, to c. 30 µm thick, pale yellowish, consisting of periclinal to irregular hyphae. Algal layer continuous or discontinuous; calcium oxalate crystals abundant, mostly small. Vegetative propagules not seen. Ascomata conspicuous, to c. 1.7 (–2.0) mm diam., ±rounded to irregular, especially in fused ascomata, apothecioid to chroodiscoid in older ascomata, erumpent, solitary or fused, often in groups of 2–several, immersed. Disc occasionally not visible to more often partly visible from above, distinctly greyish-pruinose, sometimes covered with the same whitish cottony material as thalline rim. Proper exciple not visible from above, rarely becoming visible when partly detached, whitish; thalline rim thick, indistinctly split to entire, often appearing somewhat eroded, with a ±thick whitish cottony surface, occasionally with minute needle-like crystals, usually erect to recurved. Exciple fused to apically partly free, thin, colourless to pale yellowish internally to pale to medium orange or brownish marginally, apically densely covered with greyish granules. Hymenium to 110 µm thick, moderately conglutinated; paraphyses straight to slightly bent, parallel to slightly interwoven, the tips ±distinctly thickened, slightly irregular; lateral paraphyses conspicuous, to 35 µm long. Epihymenium hyaline, with greyish granules. Asci 8-spored; tholus initially thick, becoming thin. Ascospores transversely septate, rarely submuriform, oblong to ellipsoidal or somewhat clavate with rounded to narrowly rounded or, rarely, subacute ends, brown, distinctly amyloid, 9–25 (–28) × 6–8 (–11) µm, with 4–7 (–8) × 1 (–2) locules; locules ±rounded, subglobose to more often lentiform or oblong; end cells hemispherical, rarely conical; septa thin to thick, regular at maturity; ascospore wall thick, non-halonate; endospore thick. CHEMISTRY: Thallus K–, C–, P–; no compounds detectable by TLC. |
