Lynge B 1928. Lichens from Novaya Zemlya. In Holtedahl O. Report of the Scientific Results of the Norwegian Expedition to Novaya Zemlya 1921. Oslo. 1-299.
Aerolae dispersed or few contiguous, often situated along the crevices of the stone, opaque, castaneous, 0.5-2 mm broad, 0.2-0.4 mm thick, unaltered by KOH, I and CaCl2O2, well fastened to the substratum with the whole lower white side.
Cortex 20-35 µ, most part grayish, opaque, with KOH becoming transparent, amorphous stratum none or very thin (5 µ). Hyphae intricate, pachydermatous, lumina not well seen, 2-3 u, the end-cells brown, swollen, 3-4 µ, in KOH 5 µ thick, distinct. Gonidia 7-12 µ, forming a not dense, unbroken, with single hyphae intermingled stratum, surface somewhat even. Medullary hyphae intricate, somewhat leptodermatous, more or less closely contexted. No lower cortex, but the marginal one going down on to the margin of the lower side.
Apothecia numerous, one or several in each areola, at first punctiform, deeply impressed, with a thick obtuse margin, (when single the areolae are verrucaeform), soon widened, at last more or less elevated above the thalline surface with very rough or rugose, round, dark brown disc up to 0.5 mm in diam., surrounded by an elevated, finally rather thin but distinct margin.
Excipulum more or less distinctly developed, up to 25 µ, white, hyphae parallel, in the margin scarcely spreading. Hypothecium up to 50 µ, white, grumose, with I dark blue. Hymenium 110-125 µ, white, with I dark wine-red or dirty bluish, upper 15 µ brownish yellow, surface very uneven. Paraphyses thin, 1-1.5 µ, coherent, in KOH quite free and not capitate. Asci 70-80 X 20-25 µ, broadly inflated. Spores many hundreds, 2-3.5 X 1.5-1.8 µ, broadly ellipsoid.
Pycnidia not found.
IV. Mashigin Fjord: Moraine of Reidar River, Blafjell Basin. Scantily on oxydated, granitic stone on moraine “paa dod brae”, growing with or upon Lecidea Dicksonii, Rhizocarpon geographicum and Lecanora (Aspicilia) sp.
The best developed areolae with numerous and big, rough apothecia resemble these (sic) of A. scabrida, but the smallness of the areolae, their colour and mode of affixation together with the lower hymenium and the shorter spores makes it impossible to join them. Young areolae are much alike those of scyphulifera, but the loss of the thick and dark marginal park (sic) of the exipulum (sic) is enough to keep them apart.
