in Fryday, Lichenologist, 37: 29, 2005. Basionym: Endocarpon rugosum Taylor - Fl. Hibern., 2: 258, 1836.
Synonyms: Haplocarpon glaucophaeum (Körb.) V. Wirth; Huilia glaucophaea (Körb.) Hertel; Lecidea albocoerulescens var. alpina Schaer.; Lecidea albuginosa Nyl.; Lecidea glaucophaea Körb.; Lecidea phaeenterodes Nyl.; Lecidea soredizoides (Nyl.) Vain. non (Lamy) Sandst.; Porpidia glaucophaea (Körb.) Hertel & Knoph
Description: Thallus crustose, episubstratic, continuous to rimose-verruculose, very well-developed, thick, forming large patches, white-grey to cream-coloured, usually sorediate, often delimited by a black prothallus, the soralia - when developed - irregular in outline, often formed along cracks, whitish to grey-white, the soredia coarsely granular to almost digitiform. Medulla white, I-. Apothecia rather frequent also in sorediate forms, lecideine, at first semi-immersed, then sessile and constricted at base, black, 0.8-2(-2.5) mm across, with a flat to moderately convex, densely pruinose disc and a thick, raised, usually epruinose, often flexuose proper margin. Proper exciple dark in outer part, colourless within, the hyphae 2-4 μm thick; epithecium olive-brown; hymenium colourless, 150-190 μm high; paraphyses coherent, branched and anastomosing, slightly swollen at tips; hypothecium dark brown. Asci 8-spored, elongate-clavate, with a thin, outer amyloid layer and a thickened tholus penetrated by a pore, the sides of which are strongly amyloid, Porpidia-type. Ascospores 1-celled, hyaline, ellipsoid, (15-)17-25(-28) x (5-)7-10(-12) μm. Photobiont chlorococcoid. Spot tests: cortex and soralia K-, C-, KC-, P-. Chemistry: without lichen substances, or with glaucophaeic acid, 2'-O-methylsuperphyllinic acid, very rarely with confluentic acid and methy-2-O-methylmicrophyllinate.
