Abstract. The lichens of the Zapadny Kotlin Protected Area and neighbouring area of the fort «Rif» (Saint Petersburg, Russia) have been investigated for the first time. Altogether 181 species of lichen-forming, lichenicolous and non-lichenized fungi are reported from the protected area. Bacidina sulphurella (Samp.) M. Hauck et V. Wirth is new for Russia, Arthonia phaeophysciae Grube et Matzer is published for the first time for North-Western European Russia, and 10 species are new to St. Petersburg. Three species included in the Red Data Book of St. Petersburg (Prilozhe-nie..., 2014) are known from the Zapadny Kotlin Protected Area: Arthonia helvola (Nyl.) Nyl., Pleurosticta acetabulum (Neck.) Elix et Lumbsch and Ramalina dilacera-ta (Hoffm.) Hoffm. In spite of maritime position, there are no specific maritime elements in the lichen flora of this area.

Introduction
The Zapadny Kotlin State Natural Protected Area (zakaznik in Russian) (ZK) is situated in the western part of Kotlin Island (the Gulf of Finland, Baltic Sea). The Island administratively belongs to Kronshtadt District of St. Petersburg. ZK was organized in 2012 to protect ecosystems and landscapes of Kotlin Island and occupies 1.02 km2. We also investigated small (ca. 0.13 km2) westernmost part of Kotlin Island west of ZK (the fort «Rif» and its vicinities), which was used for military aims up to the beginning of 2014. The total investigated area occupies about 1.15 km2 only, including the territories of the old marine forts «Rif» and «Shanets» (Fig.). It is a low and narrow peninsula (ca. 2.2 km x 150— 300 m) with swampy inner part and sandy seashores. Most part of the area is covered by considerably disturbed middle-aged or young black alder [Alnus glutinosa (L.) Gaertn.], aspen (Populus tremula L.) and willow (Salix spp.) stands, coming to the seashores; along the shoreline old

willow trees are also rather common. Significant part of the territory is represented by different anthropogenic open places, especially in the territories of the forts. Present in some places are short lines of Populus bal-samifera L., Quercus robur L. and Tilia sp. as well as separate trees or groups of Acer platanoides L., Fraxinus excelsior L., Larix sp., Malus sp. and Ulmus sp. (Atlas..., 2013).
The investigated territory is of special interest for lichen researches in St. Petersburg. The lichens of Kotlin Island as well as those of Baltic forts and fort islands were not investigated before, at the same time the lichen flora of island areas could be particularly specific due to marine influence. This paper presents all the obtained data on the lichen diversity of the western part of Kotlin Island and adds some new species to the lichen flora of St. Petersburg. In course of our investigations the records of 21 species only were published recently from the area (Stepanchikova et al., 2010; Vondrak et al., 2010; Pykala et al., 2012; Atlas..., 2013).
Materials and Methods
Field investigations were undertaken in 2007, 2012 and 2014. Lichens have been collected on 29 sample plots (mainly 20 x 20 m or within natural limits of plant communities) in typical habitats, and 13 additional samples were taken in different biotopes (additional collecting points). Representative specimens are mainly deposited in the lichen herbarium of the Department of Botany of the Saint-Petersburg State University (LECB), otherwise designated specially in the text (herbarium of the University of South Bohemia, Czech Republic — CBFS, herbarium of the Botanical Museum of University of Helsinki, Finland — H, lichen herbarium of Komarov Botanical Institute RAS, St. Petersburg, Russia — LE). Lichen substances were analyzed by standard technique of thin-layer chromatography (TLC) using the solvent system C (Orange et al., 2001). WGS 84 system was used for geographical (GPS) coordinates. The lichen nomenclature generally follows Nordin et al. (2011).

Results and Discussion
The revealed lichen flora of ZK and the area of the fort «Rif» altogether comprises 181 species: 175 lichens, four lichenicolous and two saprobic fungi related to lichens. The lichen Bacidina sulphurella is new for Russia, the lichenicolous fungus Arthoniaphaeophysciae is published for the first time for North-Western European Russia, 10 other species are new to St. Petersburg.
The lichen diversity of the western part of Kotlin Island is mostly concentrated in corticolous and saxicolous lichen communities: 112 species (62 % of the lichen flora) were recorded on bark of trees and shrubs, 57 (31 %) on stones, 36 (20 %) on lignum, 15 (8 %) on soil, 12 (7 %) on iron, 10 (6 %) on mosses, 5 (3 %) were lichenicolous and 2 species (1 %) were found on old rubber. The richest phorophytes were Salix spp. (68 species, 38 % of the lichen flora), Alnus glutinosa (59 species, 33 %) and Populus tremula (52 species, 29 %). It is noteworthy that willow is the species-richest tree in the study area. Salix spp. in ZK are represented by very old single trees growing mostly along the seashore; these trees are large, branched and have coarse texture of bark, so far they are able to give shelter to many lichen species. In spite of relatively big amount of aspens, epiphytic lichens on Populus tremula are not extremely diverse. The reason is that the most of aspens in ZK are rather young; the older ones on the seashore are partly covered with sand, so only young aspen bark is available for lichens. Other trees and shrubs are not so common within the study area (and usually some of them are rather young as well), therefore the diversity of their epiphytes is lower: Sorbus aucu-
paria — 42 species (23 %), Acer platanoides — 38 (21 %), Ulmus sp. — 36 (20 %), Fraxinus excelsior — 28 (15 %), Populus balsamifera — 25 (14 %), Sambucus spp. — 22 (12 %). It is noteworthy that such regionally common phorophytes as birch and pine are presented by several trees only in the western part of Kotlin Island. Their lichen cover is very poor: on Betula sp. 19 species (10 %) and on Pinus sylvestris only 10 species (6 %) were recorded, mostly Lecanora spp. and Physcia spp. All of them are widespread lichens, no one can be considered specific to phorophyte or preferring acidic bark. Saxicolous lichen communities are most diverse on concrete — 41 species (23 % of the lichen flora), 36 species (20 %) were found on granite and 6 (3 %) on brick. Granite and concrete are usually characterized by dissimilar lichen biota, but in the western part of Kotlin Island rather many (17) species present on both substrates. The main reason is that the granite within the study area is mostly incorporated in concrete constructions and evidently contaminated by concrete. Granite boulders along the seashore in ZK do not bear any lichens, probable reasons are water pollution and frequent changes of water level. Ter-ricolous lichen cover is poor and represented mostly by pioneer species of disturbed soil: Absconditella trivialis, Enchylium limosum, Psoroti-chia schaereri, Steinia geophana, Thelocarpon cf. epibolum, Verrucaria bryoctona, V. xyloxena, several species of Cladonia and Peltigera.
The most common lichen species (found at least on 20 sample plots) in the study area are: Polycauliona polycarpa, Xanthoria parietina, Lecanora hagenii, Parmelia sulcata, Hypogymnia physodes, Phaeophy-scia orbicularis, Physcia tenella, Lecanora carpinea, Melanohalea ex-asperatula, Physcia adscendens, Physcia aipolia, Scoliciosporum saro-thamni, Lecanora symmicta. Three species found in ZK are protected in St. Petersburg: Arthonia helvola, Pleurosticta acetabulum and Ramalina dilacerata (Prilozhenie..., 2014).
In general, the lichen flora of the western part of Kotlin Island can be characterized as not very rich (in comparison to other protected areas of St. Petersburg) and significantly transformed by human activity. In spite of geographic position, there are no specific marine elements in the lichen flora of this area. Sandy soil in ZK is very poor substrate with almost no lichens: sandy ground is moving because of winds. Terricolous lichens present on primary soil on fort walls, but such places are heavily trampled and therefore the lichens there are not common as well.
In comparison to other investigated areas of St. Petersburg, ZK is characterized by extremely low amount and abundance of common forest lichens growing on acidic bark (e. g. Parmeliopsis spp., Vulpicidapinas-tri) and lignicolous species, on one hand, and high abundance of some
species growing on subneutral bark of deciduous trees (e. g. Physcia spp., Ramalina fraxinea) on the other hand. The lichenological peculiarities of the territory are also rather high diversity of saxicolous (especially on concrete) and pioneer terricolous species.
