Description: Thallus crustose, more or less continuous, sometimes coarsely papillate, yellow-green to yellow-orange in sun-forms, rarely almost grey in shade-forms. Apothecia common, constricted at base, 0.5-1.5 mm across, with an orange, usually flat disc, an orange to yellow, prominent, raised proper margin, and sometimes a poorly developed thalline margin. Epithecium brownish orange, K+ red, C+ purple (in section); hymenium colourless, 50-110 μm high; paraphyses slightly moniliform, with 1.5-4 µm wide apical cells; hypothecium colourless, sometimes inspersed with oil droplets. Asci 8-spored, clavate, Teloschistes-type. Ascospores 1-septate, polarilocular, hyaline, ellipsoid (11-)12-18 x 6-11 μm, the septum 3-8 μm thick, to half the length of ascospores. Pycnidia common, darker orange than thallus, immersed. Conidia hyaline, bacilliform to slightly pyriform, c. 2 x 0.7 μm. Photobiont chlorococcoid. Spot tests: thallus K+ red, C-, KC-, P-; apothecia K+ red, C+ purple (the latter reaction not always evident). Chemistry: thallus and apothecia with fragilin (major), emodin, parietin; apothecial disc with chlorinated anthraquinones.
Note: a mainly temperate lichen, most common on old, more or less isolated deciduous trees, especially oaks; a member of a difficult and variable group.
