Thallus: crustose, often with crystals in the medulla surface: cream-colored to slightly gray, dull, uneven or slightly rugose to verrucose Apothecia: not in stromata, little raised above the thallus, lirellate lirellae: short to ±elongate, slightly curved and rarely branched, 0.4-1.5 x 0.2-0.4 mm disc: open but ±immersed within the surrounding excipular tissue, with brownish granular pruina, only old ±degenerated discs may have whitish pruina margin: entire, with an excipular lip, peripherally surrounded by a thin thalline ring, 0.02-0.04 mm wide exciple: carbonized laterally and extending above into the lip, hyaline or pale brown below (rarely carbonized) epihymenium: brown-granular, 3-5 µm thick hymenium: hyaline, not inspersed, 80-120 µm tall, I+ weakly violet paraphyses: anastomosing, overall at the lateral part of the hymenium, with brown-granular tips at least partly jutting over the hymenium subhymenium: hyaline, 15-20 µm thick asci: clavate, 65-80 x 20-25 µm, 2-4 (-5)-spored ascospores: hyaline, muriform, 7-16/3-7-locular, 30-50 x 10-23 µm, I+ violet Pycnidia and conidia: not found Spot tests: cortex and medulla K-, C-, KC-, P- Secondary metabolites: none detected. Substrate and ecology: on bark in light forests World distribution: so far only reported from tropical and subtropical regions of the New World and Australia Sonoran distribution: coastal Sinaloa. Note: Glyphis montoensis may easily be confused with Graphis britannica (= Graphina anguina auct. europ.) that occurs in northern California and shows similar excipular characters and ascospore size.
