known from a few localities; 4) easily visible species. The ecological features and the distribution of species were also taken in account. For example, preference was given to moderately rare species inhabiting highly populated and transformed territories over more rare species inhabiting less disturbed parts of the region. We suppose that the lichen red list should be combined on the base of rather other principles: 1) naturally rare species with scattered decreasing distribution area in Russia or in the World; 2) regionally rare species which are situated on the border of their distribution within LR; 3) species connected to rare and most valuable plant communities and landscapes within LR; 4) species listed in RDB of Russia (2008). The recent lichenological investigations in LR make obvious that current red list doesn’t cover the whole species diversity requiring protection. The increasing of the list to 90–95 species should make it more representative for purposes of revealing and protection of the most valuable and unique communities as well as of conservation of the whole lichen flora. According to current rules the RDB must be re-published every ten years. Unfortunately due to economical reasons the republishing of RDB of LR is shelved.

The species have similar chemistry and have been distinguished based on morphological features. The characters used to separate the species are however not always clear-cut and the species delimitation is often problematic. In this study the phylogenetic relationships of the three pendent Usnea species are reconstructed to get a framework for better understanding the taxonomy of the species. To reconstruct the phylogenetic relationships ITS1-5.8S-ITS2 sequences in a parsimony analysis were used. The variation in the sequence data was low. The results from the phylogenetic analysis confirm the taxonomic problems of the species, as none of the three species form monophyletic entities. However, most of the examined U. chaetophora specimens are included in one clade. Also most of the U. dasypoga specimens are included in one phylogenetic group. U. chaetophora and U. dasypoga might therefore be considered distinct species although there are still some problems with the species definitions. The examined U. barbata specimens are included in several distantly related clades and probably consist of several species. Preliminary findings indicate that the taxonomy of the three pendent Usnea species needs to be revised, however further studies including more loci is needed before final conclusions can be made.
ON THE LICHENS OF SVALBARD ARCHIPELAGO L. KONOREVA Laboratory of Flora and Vegetation, Polar-Alpine Botanical Garden-Institute, Kola Science Center of RAS, 184209 Kirovsk, Murmansk Region, Russia Laboratory of Lichenology and Bryology, Komarov Botanical Institute of RAS, Prof. Popov Str. 2, 197376 St. Petersburg, Russia E-mail: ajdarzapov@yandex.ru Svalbard is situated between 76°28' and 80°41' N with total area 61229 sq. km. The archipelago includes more than 1000 islands of various sizes. Arctic type of the climate is significantly mitigated by the influence of the warm Gulfstream, which bypasses the archipelago to the west and south with two branches. The topography of the archipelago is sharply dissected and more than half of the area is covered by glaciers. The territory belongs to the arctic polar desert zone, the northern arctic tundra zone and the middle arctic tundra zone. According to Øvstedal et al. (2009) the lichen flora of Svalbard includes 742 species. We have continued lichenological study in 2008–2010 with the expedition of Polar-Alpine Botanical Garden-institute. The material collected in the surroundings of Barentsburg, Pyramiden and Kolesbay (Colesdalen) settlements, Grøndalen and Grønfjorddalen river valleys, vicinity of the Aldegonda glacier and coast of the Trygghamna bay. In total we found 131 species of lichens. With the literature data the check-list of lichen flora of these areas includes 204 species. For the first time in the Barentsburg area 15 lichen species were found (total 93 species), and in the Pyramiden settlement area – 80 species (total 82 species), in the Kolesbay settlement area – 25 species (total 32 species), in the Aldegonda glacier area – 41 species (total 48 species), in the Grøndalen river valley – 7 species (total 37 species), in the Trygghamna bay – 21 species (total 23 species). Ecology and substrate analysis revealed that epilitic species are dominated in Svalbard. Rare to the archipelago species were identified (Buellia geophila (Flörke ex Sommerf.) Lynge, Euopsis granatina (Sommerf.) Nyl., Physcia tenella (Scop.) DC. ssp. marina (A. Nyl.) D. Hawksw., Protomicarea limosa (Ach.) Hafellner, Protothelenella sphinctrinoidella (Nyl.) H. Mayrhofer & Poelt, Thelocarpon epibolum Nyl.). Five new lichen species to Svalbard are: Acarospora moenium (Vain.) Räsänen, Amygdalaria elegantior (H. Magn.) Hertel & Brodo, A. pelobotryon (Wahlenb.) Norman, Diploschistes scruposus (Schreb.) Norman, Xylographa parallela (Ach.: Fr.) Behlen & Desberger. CONCERNING THE LICHEN FLORA OF SAMARA REGION E. S. KORCHIKOV Samara State University, Acad. Pavlova Str., 1, 443011 Samara, Russia E-mail: evkor@inbox.ru There are many areas in Samara region that are fairly poorly known regarding lichen flora. Our investigations since 2002 allowed to compile a checklist of lichens of Samara region that includes 322 species (Корчиков, 2006). 14 species are thought to be erroneous records: Aspicilia farinosa Arnold, Bacidia vermifera (Nyl.) Th. Fr., Bryoria implexa (Hoffm.) Brodo et D. Hawksw., B. subcana (Nyl. et Stiz.) Brodo et D. Hawksw., Chaenothecopsis viridireagens (Nádv.) Schmidt., Cladonia decorticata (Flörke) Spreng., C. digitata (L.) Hoffm., C. glauca
