Description: Thallus crustose, dull to bright yellow, often white pruinose, forming a continuous areolate crust. Areoles/ squamules (100-) 248 ± 111 (-550) µm thick (n = 44) and (0.18-) 0.98 ± 0.51 (-2.6) mm wide (n = 140). Areoles and squamules flat, covered by blastidia or by laminal soralia of limonia type; soredia/ blastidia (26-) 85 ± 54 (-320) µm diam. (n = 138). Cortex/ alveolate cortex (4-) 15 ± 10 (-55) µm thick (n = 109). Apothecia frequent, c. (0.25-) 0.6 ± 0.25 (-1.6) mm diam. (n = 114). Disc in mature apothecia slightly concave to flat. Exciple (70-) 121 ± 31 (-200) µm thick (n = 25), zeorine, thalline exciple prevailing in old apothecia, sometimes covered by blastidia/ isidia. Hymenium (60-) 78 ± 17 (-130) µm thick (n = 50). Paraphyses tips widened to (3.0-) 4.5 ± 0.5 (-6.0) µm (n = 72). Ascospores (9.0-) 13.0 ± 1.5 (-16.0) x (3.0-) 6.5 ± 1.0 (-9.0) µm (n = 77); length/breadth ratio c. 2.0. Ascospore septa (3.0-) 5.5 ± 1.0 (-8.0) µm thick (n = 77), c. 0.42 of ascospore length. Conidia (2.5-) 3.5 ± 0.8 (-5.5) x (1.0-) 1.15 ± 0.25 (-1.5) µm (n = 33). (Vondrák et al. 2009: 597).
