Pannaria conoplea (Pers.) Bory

    Thallus foliose, lobes to 0.5-1 cm, intricate and partially overlapping or rosette-forming 3-5 cm diam., margins ascending, up-turned, incised, upper surface of lobes slightly pruinose, covered with granular or coralloid (gymnidia) lobules, pale grey-bluish, grey, lobules soralia or isidia-like potentially spreading to the whole thallus, grey-blue when moist, dull or pale grey when dry, lower surface markedly tomentose, grey-brownish to grey-blackish tinged blue. Apothecia usually absent or extremely rare, 0.5-1 mm diam., disc brown-red, margin isidiate. Ascospores simple 15-19 x 9-10 µm without perispore, 20-24 x 10-12 µm with perispore. Cortex: C-, K-, KC-, Pd+ red-orange. Oceanic trends, on mossy trunks (mainly at their base) of trees in old oceanic woodlands, very seldom on mossy rocks in the same forests. See Degelia atlantica, darker and of which the lobe margins are not incised. See also Degelia cyanoloma devoid of small lobules and with black apothecia.*
