    Introduction

    Exploration of biodiversity in mountainous ecosystems represents important fundamental research. Mountains harbour a large number of species diversity, especially in protected areas. The lack of data about lichen diversity in protected areas in Dagestan is a gap in knowledge that needs to be filled. This is the aim of our work.

    The lichens of some protected areas of Dagestan have been investigated to some extent: Sarykum barkhan State Sanctuary - 40 species (Urbanavichus et al., 2010) and Samurskiy State Sanctuary - 138 species (Ismailov et al. 2017). The two latter surveys revealed 97 new species to Dagestan, 18 to the Caucasus and 5 to Russia.

    The present study in the State Wildlife Sanctuary Tlyaratinskiy (further Tlyaratinskiy Zakaznik) in high-mountainous part of Dagestan enhances knowledge of lichen flora in protected areas of Dagestan. Only sixteen lichen species were known in the Tlyaratinskiy Zakaznik before our investigations started (Krasnaya ..., 1998; Ismailov, 2015; Ismailov 2017). As a result of our survey 149 new species were registered in different parts of the Tlyaratinskiy Zakaznik. In our total check-list, 165 species of lichens and lichenicolous fungi of the Tlyaratinskiy Zakaznik are provided.

    Study area

    The Tlyaratinskiy Zakaznik is situated in Dagestan, along the eastern part of the Greater Caucasus Range at the border with Georgia and Azerbaijan (Fig. 1). The Zakaznik is located in Tlyarata District in the upper reaches of the Avarskoe Koisu River (the Dzhurmut River Basin) and covers the northern slopes of the Greater Caucasus Range and the southwestern spurs of the Nukatl Range. On the south it borders on the La-godekhi Nature Reserve of Georgia and Zagatala State Reserve of Azerbaijan. The area of ​​the Tlyaratinskiy Zakaznik is 83500 ha. The altitudinal range of the protected area is 1500-3932 m. The annual rainfall is 8001000 mm. Relative air humidity is 65-75%. The absolute minimum of temperature is -33 ° C in January. The hottest months are July and August with maximum temperature of 35 ° C. Bedrock is represented by variable slates throughout the territory (Fizicheskaya ..., 1996; Yarovenko et al., 2004).

    Various mountainous habitats are present in the Tlyaratinskiy Zakaznik - nival zone with glaciers and snowfields, alpine and subalpine meadows, scrubby birch woodlands, pine, mixed and deciduous mountain forests, meadows and shrub thickets, rocky slopes with xerophytic

    investigated sites).

    vegetation, outcrops of rocks and cliffs in river valleys. Cultivated landscapes (settlements and fields) only occupy small areas. Pine forest of Pinus kochiana C. Koch predominates in the lower part of the Tlyaratinskiy Zakaznik. Large areas above altitude of 1700-1800 m are covered by mixed forests of pine with Betula litwinowii Doluch., B. pendula Roth, B. raddeana Trautv. and Acer species (Fig. 2). Mixed forest is replaced by scrubby birch woodland at about 2300-2500 m. At timberline (25002600 m), forests are gradually replaced by dwarf shrubs of Rhododendron caucasicum Pall. Most of the area of ​​the Tlyaratinskiy Zakaznik is located above the timberline and is covered by subalpine and alpine meadows. Above 3000 m in landscape slate talus slopes are prevailing.

    The flora of the Tlyaratinskiy Zakaznik consists of more than 600 species of vascular plants including 60 species of trees and shrubs. There are

    many endemic [120 species, e. g. Dianthus tlaratensis Husseinov, Gen-tiana lagodechiana (Kusn.) Grossh., Paeonia mlokosewitschii Lomakin, Primula juliae Kusn.] And vulnerable [20, e. g. Colchicum speciosum Steven, Mandenovia komarovii (Manden.) Alava, Pseudovesicaria digitata (C. A. Mey.) Rupr., Vavilovia formosa (Steven) Fed.] Species (Yarovenko et al, 2004; Krasnaya ..., 2009).

    Material and methods

    Specimens (about 400) were collected from 5 localities (see list below) during a short field work in the Tlyaratinskiy Zakaznik in August 2014 (Fig. 1). Morphological and microscopic investigations were done by light microscopy and using routine spot tests (KOH, KI, hypochlorite, paraphenylenediamine and UV light) in Mountain Botanical Garden DSC RAS ​​and Komarov Botanical Institute RAS. The geographic coordinates (WGS84) and altitudes of each locality were measured by hand-held GPS

    navigator. The lichen nomenclature mainly follows Nordin et al. (2011). For the species new to Dagestan, the information of their distribution in the Caucasus and herbarium specimen number are given. The specimens are stored in the herbaria of Mountain Botanical Garden, Dagestan Science Centre RAS, Makhachkala (DAG).

    Discussion

    The present species list from the Tlyaratinskiy Zakaznik contains 162 lichenized fungi and 3 lichenicolous fungi (Arthonia intexta, Dactylos-pora saxatilis, Sphaerellothecium reticulatum) categorized in 82 genera and 30 families. Caloplaca diphyodes is new to the Russian Caucasus, but it was previously reported from the Armenian Caucasus (Harutyun-yan et al., 2011). Arthonia intexta, Bryoria smithii, Protoparmelia badia and Sphaerellothecium reticulatum are new to Dagestan. The territory of the Tlyaratinskiy Zakaznik is the only known locality in the Caucasus for the species Carbonea assimilis, Lecidea silacea, Rhizocarpon ridescens and R. superficiale. The species Caloplaca diphyodes, Candelariella an-tennaria, Rhizocarpon lavatum are known in the Russian Caucasus only from the Tlyaratinskiy Zakaznik. Among the vulnerable lichens Tornabea scutellifera and Usnea florida have been included in the Red Data Book of Russia (Krasnaya., 2008).

    At this stage most epiphytic lichens were recorded on the bark of Be-tula sp. (51 species) and Pinus kochiana (48). These phorophytes are dominant in forests of the study area. 24 species were recorded on Quercus macranthera, 8 species on Populus tremula.

    Few species were recorded on dead wood of rotten stumps, logs and snags, e. g. Cladonia coniocraea, C. fimbriata, Evernia prunastri, Flavo-parmelia caperata, Flavopunctelia soredica, Hypogymnia physodes, Mi-carea misella, Vulpicida pinastri.

    Most interesting and rare terricolous species are Allocetraria madre-poriformis, Bryoria bicolor, Fuscopannaria praetermissa and Protopan-nariapezizoides. Each was found locally in one of the investigated sites.

    The saxicolous Gyalolechia lenae was previously known only from calcareous substrate, but in the study area it is growing on non-calcareous slate. Pertusaria excludens in the Russian Caucasus is known only from Dagestan. For the Caucasus this species has also been reported from Azerbaijan (Barkhalov, 1983). Apart from Dagestan, Carbonea assimilis is known in Russia only from the Arctic part of Far East (Urbanavichus, 2010). Lecidea silacea, Rhizocarpon ridescens and R. superficiale, known in northern and arctic regions of Russia, are in the Caucasus only reported from Dagestan.

    The most common lichens found in 3 or more sites include Anapty-chia ciliaris, Blastenia hungarica, Candelariella vitellina, Cetraria aculeata, Cladonia furcata, C. gracilis, Dimelaena oreina, Evernia di-varicata, Flavocetraria cucullata, Flavopunctelia soredica, Lecanora polytropa, Lecidella euphorea, Leptogium saturninum, Lobothallia alpho-placa, Melanohalea exasperatula, Parmelia sulcata, Peltigera venosa, Physcia caesia, Physconia distorta, Protoparmeliopsis muralis, Ramalina farinacea, Rhizocarpon disporum, Rhizoplaca chrysoleuca, Umbilicaria cylindrica, Vulpicida pinastri, Usnea hirta and Xanthoparmelia steno-phylla.
