[in Russian with English abstract: ] The epiphytic species Woessia lignicola, comb. nov., is newly reported for Asia and Russia from the Altai Territory (South Siberia). The species identity is supported by morphological examination and molecular-phylogenetic data (nrITS sequence). This finding extends the known distribution of the species eastward by more than 4000 km. In light of the recent resurrection of the genus Woessia, we propose the new combination W. lignicola (based on Bacidina lignicola). Keywords: Bacidina, Woessia, biogeography, ITS, new record, taxonomy, Altai-Sayan Mountain system, Altai Territory, Salair Ridge.
