Soredia fine, with individual granules convex to spherical, 12–40 μm wide, becoming agglomerated and forming granules to 200 μm wide. Medulla usually not apparent, in thick thalli sometimes indistinct and yellow. Photobiont cells ±globose, 15–18 μm wide, solitary or clustered. Apothecia not seen in Australian specimens [Reported to be rare, to 0.5 mm wide, ±superficial, rounded or distorted-angular; disc pale orange, often yellow-pruinose, plane to slightly convex; margin thin, ecorticate, soon becoming excluded; hymenium colourless, to 50 μm thick; epihymenium colourless, to 18 μm thick, composed of a reticulate layer of richly branched paraphyses; hypothecium colourless, poorly developed; ascospores mostly 3-septate, narrowly ellipsoidal, straight or curved, 9–14 × 3 μm (Tønsberg, 2004)] CHEMISTRY: Thallus K+ orange, C–, KC–, P+ orange, UV+ dull orange; containing calycin. |
