Two new species of Arthoniaceaeare described from old-growth European forests: Arthonia thorianafrom Horner Combe in Great Britain and Inoderma sorediatumfrom the Białowieża Forest in Poland. Phylogenetic analyses using mtSSU sequences were used to determine the generic affiliation of the two species. Arthonia thorianais characterized by a non-lichenized white thallus, pallid brown, white pruinose ascomata of 0·12–0·30 mm diam., richly anastomosing paraphysoids and (1–2–)3-septate ascospores of 9–12×3·0–3·5 µm. Inoderma sorediatum differs from all other species of the genus by a sorediate thallus and the production of confluentic acid. It is the sister species to I. afromontanum in our phylogenetic analyses. The discovery of the new species supports the high value of these forests for biodiversity action plans. Phylogenetic analyses also place Schismatomma niveumin the Arthoniaceae and the new genus Snippociais described to accommodate it. The genus Lepranthais resurrected for its type species (L. cinereopruinosa). A lectotype is designated for Arthonia pruinosella.
