Vainio, E. (1909). Lichenes in viciniis stationis hibernae expeditionis Vegae prope pagum Pitlekai in Sibiria septentrionali a Dre. E. Almquist collecti. Praefationem scripsit F. Almquist. Arkiv for Botanik, Band 8, No. 4: 11-175.
Thallus crustose, thin, moderately continous, slightly verruculose-unequal, soredia absent. Gonidia cystococcus, globose, diam. 0.012-0.016 millim. (only simple seen), membrane middling. Apothecia adnate, initially convex and immarginate, bluish/dark greyish-dark brown/grayish-brown, almost one colour, opaque. Excipulum thin, pale, formed from radiating and conglutinated hyphae, tubules thin, membrane moderately thick, in KHO gelatinous-turgid-like. Hypothecium hyaline. Hymenium I persistently becoming blue. Epithecium becoming dilute dark brown/grayish-brown-pale, slightly granulose. Paraphyses tightly coherent, pr. p. branched and branch-connected, apices not thick, tubules thin, membrane in KHO gelatinous-turgid-like. Spores 8, distichous, hyaline, oblong, apices rounded or obtuse, pr. p. 1- septate, and also rarely 2-septate, pr. p. simple, 0.012-0.016 millim. long, 0.004-0.008 millim. thick.—Habit is similar to L. symmicta f. saepincola, yet it differs with its white thallus and spores. Furthermore, it brings to mind L. meiocarpa Nyl. and is allied in position with L. hemipoliella Nyl.
