Thallus: yellow to yellow-orange, of dispersed squamules, or continuous, areolate. Areoles/squamules (80-) 121 ± 28 (-180) µm thick (n = 16) and (0.2-) 0.65 ± 0.3 (-1.4) mm wide (n = 34). Areoles and squamules flat, smooth or covered by blastidia, with laminal or marginal soralia of confusa, flavocitrina or limonia type; soredia (18-) 31 ± 9 (-43) µm diam. (n = 28), sometimes gathered to small consoredia. Cortex poorly developed; alveolate cortex (7-) 18 ± 8.5 (-40) µm thick (n = 15). Apothecia infrequent (25% of samples fertile), c. 0.4-1.0 mm in size (n = 7). Discs observed in mature apothecia ± flat. Exciple 50-110 µm thick (n = 7), zeorine, but appearing biatorine; in young apothecia, the true exciple fills the whole exciple width, as the thalline exciple is hidden below the true exciple. Hymenium 70-80 µm thick (n = 9). Paraphyses tips widened to (3.5-) 4.5 ± 0.5 (-5.5) µm (n = 18). Ascospores (10.0-) 11.5 ± 1.0 (-13.0) x (4.5-) 5.5 ± 1.0 (-7.0) µm (n = 17); length/breadth ratio c. 2.1. Ascospore septa (3.5-) 5.0 ± 1.0 (-7.0) µm thick (n = 17), c. 0.43 of ascospore length. Conidia c. 3-3.5 x 1-1.5 µm. (Vondrák et al. 2009: 593).
