| Flavoparmelia haysomii (C.W.Dodge) Hale | ||

| Thallus loosely adnate to adnate, to 8–15 cm wide. Lobes laterally imbricate to ±contiguous, 1–3 mm wide; apices rotund. Upper surface pale straw-coloured to yellow-green, broadly undulating, rugose centrally, dull to slightly shiny, often with reticulate white maculae towards lobe apices, lacking isidia; dactyls laminal on older lobes, large, thick, simple or sparingly branched, forming pustules, fragile, rarely erumpent apically and forming granular soredia. Medulla white throughout, or lower medulla yellow. Lower surface with sparse rhizines; rhizines simple or dichotomously branched, black in thallus centre sometimes becoming pale towards margins. Apothecia rare, sessile to subpedicellate, 2–4 mm wide; disc deeply concave at maturity, cinnamon-brown; thalline exciple rugulose but not pustulate. Ascospores tapering to one end, 12–15 × 7–8 µm. Pycnidia scattered. Conidia bacilliform, c. 6 × 1 µm. CHEMISTRY: cortex K-, UV-; medulla K-, C-, KC-, P+ orange-red; pigmented medulla K+ purple; containing usnic, protocetraric acid (major), caperatic acid (major), ±skyrin (in pigmented medulla), ±gyrophoric acid and with or without unidentified compounds. | ||
