Based on the results of field works mainly in 2009-2017, new data on new and noteworthy lichen spe-cies from Southern Siberia are presented. The lichen specimens were collected predominantly by the first author in themountain dark coniferous forests with Abies sibirica, Pinus sibirica, Populus suaveolens, Sorbus sibirica and Padus avium in Baikal State Nature Biosphere Reserve (Khamar-Daban Range, Republic of Buryatia) and Ergaki Nature Park (Western Sayan Mts, Krasnoyarsk Territory). In the present paper, 14 species are reported as new for the lichenflora of study areas, among them: Biatorella flavella is reported for the first time for Russia, Ropalospora viridis is new to Asia, 5 species - Bryoria vrangiana, Dictyocatenulata alba, Elixia flexella, Lecanora compallens and Micarea soralifera - are new for Siberia, Chaenotheca subroscida and Fuscidea arboricola are new for Southern Siberia, 4 species - Absconditella annexa, Caloplaca sorocarpa, Bryobilimbia sanguineoatra and Protothelenella sphinctrinoi-della are new for Baikal Siberia, Caloplaca sorocarpa is new for Krasnoyarsk Territory, Pilophorus strumaticus is new for Republic of Buryatia. A full text of herbarium labels, some comments and comparisons with similar speciesare given. The information about distribution of all mentioned species in Russia and world is also presented. Our re-cords considerably extend the ranges or fill gaps in the formerly disjunctive distributions of these species.
