Pannaria fulvescens (Mont.) Nyl.
Thallus foliose-lobate, rather loosely attached, suborbicular, to 8 cm diam., corticolous. Lobes 8-15 mm long and 1-4 mm broad, radiating or ± canaliculate, undulate to cuneate-flabellate, contiguous to imbricate, margins rounded, shallowly incised or crenate, sinuous, ± ascending. Upper surface continuous, wrinkled, especially at sinuses and near apices, minutely verrucose-scabrid (×10 lens) and occasionally minutely tomentose, yellowish to fawnish-brown or greyish-yellow, sorediate. Soralia limbiform, bluish, conspicuous, mainly marginal, soredia coarse, granular, crowded, bluish. Lower surface pale, white at margins, buff centrally, ± evenly covered with short, whitish tomentum, and in places with ± dense tufts of white to blue-black, squarrose rhizines. Apothecia rare, sessile, 1-3 mm diam., disc pale to dark brown-red or blackened, plane or subconcave, thalline margin thick, elevated, sulcate, often pulverulent-sorediate, whitish or bluish, concolorous with soralia. Ascospores thick-walled, rounded at one end, contents granular, 12-18 × 5-10 µm. Chemistry: Cortex K-, C-, KC-, Pd+ red. Pannarin.
Thallus small, lobate-foliose, spreading, loosely attached, muscicolous or corticolous, to 2 cm diam. Lobes plicate-rugose when dry, expanded inflated, appearing subgelatinous when wet, margins crenate, slightly thickened, ± ascending. Upper surface dark greenish-blue, tinged whitish, smooth, matt, minutely scabrid at margins ± isidiate. Isidia tuberculate, swollen or gnarled, ± globose 0.1-0.2 mm diam., marginal at first, then spreading over upper surface or onto margins of lower surface, bluish-white or blue-black. Lower surface white or pale buff, tomentose at margins with brown squarrose rhizines centrally. Prothallus absent. Apothecia not seen.
