| Thallus endophloeodal to epiphloeodal, to c. 100  µm thick, olive to pale brownish green, sometimes with reddish spots, glossy,  smooth, continuous to slightly verrucose, non-rimose. True cortex hyaline to  slightly yellowish, to c. 30 µm thick, consisting of periclinal hyphae. Algal  layer well developed, continuous; calcium oxalate crystals large and clustered.  Vegetative propagules not seen. Ascomata conspicuous, to c. 1.8 mm diam., ±rounded  to slightly irregular, perithecioid, solitary, rarely marginally fused,  distinctly emergent, occasionally slightly verrucose, hemispherical to  urceolate. Disc not visible from above, in older stages the pores filled with  the columella tip, ±pruinose, off-white to pale brownish, free, entire. Proper  exciple not visible from above; thalline rim margin small to moderately broad,  opening late, to c. 0.3 mm diam., ±rounded, entire to slightly eroded, ±raised  and funnel-shaped to annulate, off-white to pale brownish, often slightly pruinose  internally; thalline rim incurved. Proper exciple fused, moderately thin to  moderately thick, dark brown to carbonised, non-amyloid. Hymenium to c. 500 µm thick,  not inspersed, strongly conglutinated; paraphyses thin, bent to slightly curly distally,  slightly interwoven, unbranched to sparingly branched towards the margins and  columella, with moderately thickened tips; columellar structures well developed, to c. 250 µm wide, entire, conical,  with a narrowly rounded tip, carbonised, covered with greyish or brownish  granules. Epihymenium hyaline, with greyish or brownish granules. Asci 1 (–2)-spored;  tholus initially thick, thin when mature. Ascospores muriform,  oblong-ellipsoidal, often slightly irregular, with ±rounded to narrowly rounded  ends, hyaline, distinctly amyloid, 170–250 × 35–45 µm, with numerous locules;  locules ±rounded to ±angular, subglobose to irregular; transverse septa  indistinct and irregular; ascospore wall and endospore initially thick,  becoming thin; wall non-halonate. Pycnidia not seen. CHEMISTRY: Thallus K+ yellow → red, C–, P+ orange; containing salazinic acid (major). | ||
