Thallus crustose, leprose, creamy white, pale yellow-grey or pale yellow-green, forming extensive irregularly spreading patches to 7 cm wide, or small irregularly rounded colonies 5–20 mm wide which eventually coalesce, thin or up to 250 μm thick. Margin usually delimited, well-defined lobes absent, but sublobes often present, 0.2–1.0 mm wide. Soredia dispersed or forming a thick continuous layer, ±globose, 20–50 μm wide, commonly aggregated in roundish clumps (consoredia) to 100–225 μm wide, with long projecting hyphae at the base and along the margins (to 0.2 mm long) and shorter projecting hyphae within
(50–125 μm long). Medulla white and patchily distinct, or absent. Hyphae 2–4 μm thick. Lower surface not apparent, without a tomentum.Photobiont cells ±spherical, 5–12 μm diam., sometimes with autospores visible inside. Hypothallus pale brown to black or not apparent. CHEMISTRY: Thallus K–, C–, KC–, P–, UV–; containing methyl barbatate (major), barbatic acid (trace), methyl 2’-O-methylbarbatate (trace) |
