Description: Thallus epiphyllous, farinose but rather compact, with an irregular surface, matt, pale green with tinges of yellow or blue, + continuous over the leaf surface. Photobiont: most probably a species of the Chlorococcaceae, with spherical, green cells, 5-12 µm diam. Apothecia usually numerous, sometimes absent, circular when young, eventually becoming lobulate, with an irregular edge, 0.15-0.2(-0.3) mm diam., less than 0.1 mm in height, without any distinct margin, disc very pale to pale brownish orange, almost white when young; becoming brownish when old, flat or convex. Exipulum poorly developed, best seen in young apothecia, almost absent in older ones, hyaline and without crystals, made of a loose network of branched and anastomosed hyphae, cells without any swelling at the margin. Hypothecium hyaline, less than 10 µm thick. Hamathecium of branched and anastomosed paraphyses. Asci of the Byssoloma-type (sensu Hafellner 1984: 315), 35-45 x 10-15 µm, 8-spored. Ascospores ellipsoid, 3-septate, not constricted at their septa, with a distinct gelatinous halo, 10-14 x 2.5-4 µm. Pycnidia always numerous, sessile, globose, usually distinctly constricted at their base, 0.1-0.15 mm high, 0.05-0.1 mm diam., sometimes with a spherical glut of conidia at their apical ostiole, wall white to very pale brown. Conidia numerous, bifusiform to slightly clavate, 4-5 x 1-1.5 µm (Sérusiaux 1996: 219).
