Descriptions
Pseudocyphellaria billardierei (Delise) Räsänen
Thallus irregularly spreading, loosely attached, apices ± free and subascending, 5-15(-25) cm diam., corticolous. Lobes regularly dichotomously to subdichotomously branching, 1-8(-12) mm wide, 1-10 cm long, well separated, discrete at margins, complex and often entangled centrally, rather flat, apices acute or truncate, rounded or bifurcating, margins entire, often thickened, smoothly rounded, without projecting pseudocyphellae. Upper surface matt or glossy, bright lettuce-green when wet, pale green or olive-brownish when dry, shallowly to deeply faveolate, interconnecting ridges smooth and rounded or sharp. Lower surface white or pale buff, conspicuously wrinkled to ± bullate, margins conspicuously thickened, ± glabrous in a narrow to broad marginal zone, thinly to densely tomentose often to margins, tomentum pale, whitish, silky near margins, entangled, brown-black centrally. Pseudocyphellae scattered to ± frequent, white, raised, verruciform, 0.05-0.2 mm diam., on interconnecting ridges, decorticate area small, depressed-punctate or indented below surrounding margins, rarely flat, margins thin ± puckered. Medulla white. Photobiont green. Apothecia marginal or submarginal, rather scattered, often developed towards lobe apices, subpedicellate, 0.5-2.5 mm diam., disc dark red-brown to black, roughened, epruinose, subconcave to plane and ± undulate, margins persistent or excluded in mature fruits, minutely crenate or verrucose, pale-red-brown to flesh-coloured, exciple pale red-brown, concolorous with margins, minutely verrucose-areolate, rarely pubescent or tomentose. Ascospores brown, ellipsoid-fusiform, simple at first, polaribilocular at maturity, 22-30 × 6.8-10.2 µm. Chemistry: Methyl evernate, tenuiorin, methyl lecanorate, methyl gyrophorate, hopane-6α,22-diol, (zeorin), 6α-16βdiacetoxyhopan-22-ol, 6α-acetoxyhopane-16β,22-diol, 6α-acetoxy-22-hydroxyhopan-23-oic acid, 6α-22dihydroxyhopan-23-oic acid, norstictic and stictic acids.
