| Biblioth. Lichenol. 78: 161 (2001). T: Yilliminning Rock, c. 12 km E of Narrogin, W.A., 32°50’S, 117°23’E, 350 m, on decorticated twigs of shrubs, 16 Aug. 1994, K. & A.Kalb s.n.; holo: CANB; iso: Herb. K.Kalb. | ||
| Thallus pale yellow to pale tan, areolate; areolae confluent, 0.2–0.5 mm wide, to 0.1 mm thick, sorediate; soralia to 0.3 mm wide, originating from the margins of the areolae, but soon spreading over the thallus surface; soredia farinose, grey with a ±bluish tinge. Photobiont cells to 14 µm wide. Apothecia very rare, sessile, round, 0.3–0.4 mm diam.; disc jet-black, glossy, plane, becoming convex; margin thin, black and glossy, persistent or becoming excluded in old apothecia. Epithecium 7–9 µm thick, chocolate-brown, K+ olive-grey. Excipulum similarly coloured. Hymenium 40–45 µm thick, pale yellow-brown to hyaline, K–. Paraphyses conglutinate, sparingly branched and anastomosing, 2–3 µm thick, regularly tapered, inspersed with minute brownish granules that dissolve in K; apices hyaline, not expanded. Hypothecium 50–60 µm thick, hyaline to pale brown, K–; subhypothecium hyaline, K+ intense yellow. Asci 28–35 × 10–13 µm. Ascospores narrowly ellipsoidal, 6–8 × 2.5–3.5 µm. Pycnidia not seen.
