Lichenologist 38: 137 (2007) T: western slopes of Strzelecki Peaks, Flinders I., Tas., 27 Dec. 1997, G.Kantvilas 301/97; holo: HO; iso: BM. |

| Thallus pale grey-green, olive-green to dull olive-brown, initially rimose-areolate, with the areolae plane to convex, c. 0.1–0.3 mm wide and to c. 0.35 mm thick, not delimited by a prothallus, soon becoming blastidiate, abraded and sorediate and forming a rather coarse cracked granular crust to 0.75 mm thick. Soralia pale green to pale fawn-brown, discrete and at first rather punctiform, becoming diffuse. Photobiont cells 6–18 µm wide. Apothecia round to irregularly rhomboidal, solitary or sometimes with adjacent ones fused, 0.2–1.0 mm wide, sessile; disc dull to bright red-brown or dark brown, basally constricted, but generally nestled among soredia and/or blastidia and appearing rather sunken, plane, undulate to ±convex, epruinose; margin very thin, concolorous with the disc or a little paler, usually becoming rapidly excluded. Exciple 20–60 µm thick, colourless to pale orange, K+ yellow → red. Epihymenium c. 10 µm thick, red-brown, K+ olive-brown. Hymenium 30–45 µm thick, colourless, K–. Hypothecium colourless, 70–140 µm thick, K–; subhypothecium to 40 µm thick, colourless, K+ yellow → red. Paraphyses sparingly branched and anastomosing, 1–2 µm thick; apices distinctly capitate, rounded, olive-brown (after the addition of K), 2–4 (–4.5) µm thick. Asci 28–40 × 12–17 µm. Ascospores ellipsoidal to fusiform-ellipsoidal, simple, occasionally with a plasma bridge and appearing spuriously septate, 8.5–12.0 × 3.5–5.5 µm. Pycnidia not seen. CHEMISTRY: Thallus and subhypothecium K+ yellow → red, C–, P+ yellow; containing norstictic acid (major), connorstictic acid (minor or trace). |

| Endemic and rare on wood, but relatively common on rocks, in open, rather exposed situations at lowland to alpine elevations, especially in dry-sclerophyll vegetation. Occurs in all States and the A.C.T. | ||
