Beih. Nova Hedwigia 79: 292 (1984)

Verrucaria badia Hoffm., Flecht. Deutschl. 182 (1796); — Lecanora badia (Hoffm.) Ach., Lichenogr. Universalis 407 (1810).

T: Germany, “In harcyniam ad saxum trapesium (Trapp suecis)”; holo: n.v. ..

  Thallus pale grey-brown to dark brown, thin, rimose and areolate to coarsely warted, ±centrally rugose to bullate, to 10 cm wide, 1.5–2.5 mm thick, effuse or rarely delimited by a thin black prothalline line. Areolae irregularly shaped, contiguous, 0.6–1.5 (–3.0) mm wide; upper surface subconvex to convex, uneven, lacking isidia. Apothecia common, often crowded, immersed to sessile, ±constricted at the base, round or becoming subangular from crowding, 0.4–2.2 mm wide; disc chestnut-brown to dark brown or brown-black, weakly concave to ±plane or markedly convex, glossy, usually darker than the margin; thalline exciple concolorous with the thallus, ±persistent. Proper exciple poorly delimited, 140–200 µm thick. Epihymenium
10–20 µm thick. Hymenium 50–60 µm thick. Hypothecium 80–100 µm thick, colourless to pale yellow. Paraphyses with clavate to capitate apical cells 4–6 μm wide, with a pale brown wall surrounded by a dark brown cap. Ascospores ellipsoidal-fusiform, with distinctly pointed apices, 8–13 × 3–5 µm. Conidia pleurogenously formed, acicular, straight, 6–11 × 0.7–1.2 µm.
CHEMISTRY: Cortex K–, C–, KC+ pink, P–, N–; medulla K–, C–, KC+ pink or KC–, P–, UV+ white; containing lobaric acid (major), oxolobaric acid (minor), conlobaric acid (trace), sublobaric acid (trace), norlobaric acid (trace), ±zeorin (minor), ±usnic acid (minor).
