Description: Lichen. Thallus crustose, yellow, of dispersed squamules, rarely continuous, areolate. Squamules (70-) 96 ± 17 (-140) µm thick (n = 16) and (0.12-) 0.4 ± 0.17 (-0.75) mm wide (n = 60). Squamules flat, smooth, with marginal soralia of flavocitrina type, but the soralia sometimes expand and cover the complete surface of the squamules. Soredia (16-) 29 ± 9 (-65) µm diam. (n = 56), sometimes gathered into consoredia. Cortex thin, usually of 1-2 layers of cells; alveolate cortex (4-)9 ± 5(-25) µm thick (n=44). A white or yellow fibrillar prothallus was observed on smooth substrata. Apothecia infrequent (30% of samples fertile), (0.3-) 0.43 ± 0.1 (-0.75) mm diam. (n = 24). Disc in mature apothecia slightly concave to flat. Exciple (70-) 85 ± 13 (-110) µm thick (n = 16), zeorine, the true exciple/thalline exciple ratio very variable; thalline exciple enlarged with age. Hymenium (65-) 75 ± 6 (-80) µm thick (n = 14). Paraphyses tips swollen to (3.0-) 5.0 ± 1.0 (-7.0) µm (n = 32). Ascospores (10.0-) 11.5 ± 1.25 (-14.5) x (4.0-) 5.5 ± 1.0 (-7.0) µm (n = 27); length/width ratio c. 2.1. Ascospore septa (3.0-) 4.5 ± 1.0 (-7.0) µm thick (n = 27), c. 0.39 of ascospore length. Conidia (2.0-) 3.25 ± 0.5 (-4.0) x (1.0-) 1.15 ± 0.25 (-1.5) µm (n = 14). (Vondrák et al. 2009: 595-596).
