Thallus: yellow (with orange tint in populations from Crete) areolate, bullate to minutely squamulose. Areoles dispersed or contiguous and then overgrowing each other, forming thick crusts in luxuriant populations, (90-) 190 ± 75 (-450) µm thick (n = 53) and (0.32-) 0.86 ± 0.43 (-2.8) mm wide (n = 121). When the thallus is welldeveloped, its surface is coarsely granular; granules (70-) 180 ± 66 (-380) µm diam. (n = 135). Cortex present, (5-) 17 ± 7.5 (-46) µm thick (n = 134). Apothecia frequent, (0.2-) 0.6 ± 0.2 (-1.3) mm diam. (n = 97). Disc in mature apothecia slightly concave to flat, never distinctly convex. Exciple (40-) 100 ± 34 (-210) µm thick (n = 57), often crenulate; true exciple fills c. 1/3-1/2 of the exciple width, thalline exciple prominent. Hymenium (50-) 68 ± 12 (-100) µm thick (n = 48). Paraphyses tips widened to (3.0-) 5.0 ± 1.0 (-0.7) µm (n = 80). Ascospores (10.0-) 13.0 ± 1.5 (-18.0) x (4.0-) 6.5 ± 1.0 (-9.0) µm (n = 78); length/breadth ratio c. 2.0. Ascospore septa (3.0-) 5.0 ± 1.0 (-7.0) µm thick (n = 78), c. 0.4 of ascospore length. Conidia (2.0-) 2.8 ± 0.3 (-3.5) x (1.0-) 1.2 ± 0.2 (-2.0) µm (n = 52). (Vondrák et al. 2009: 591-592).
