Новинки в лихенофлоре заповедника «Витимский» (Восточная Сибирь)

Abstract

As a result of lichenological studies in the vicinity of Lake Oron (Vitimsky State Nature Reserve) and revision of herbarium material, 9 species of lichens were identified that had not previously been listed for a specially protected natural area. Some of the identified species have a wide distribution (Absconditella lignicola, Bryoria americana, Pyxine meissneriana, Trapeliopsis flexuosa and Multiclavula vernalis), and some have limited ranges covering only the eastern part of Asia, Alaska and Southern Siberia (“Cetraria” annae, Parmelina yalungana and Phaeophyscia dessecta), with “Cetraria” annae and Phaeophyscia dessecta so far they are known only for the territory of Russia. Some of these species (Absconditella lignicola, Trapeliopsis flexuosa and Multiclavula vernalis) probably have a wider distribution in the reserve, but without spore-bearing structures they are difficult to identify. Herbarium material attributed to Parmelina yalungana does not raise doubts regarding its species identity, however, the discovery of specimens with a macular upper surface in eastern Eurasia requires additional careful study.
