Приведены результаты лихенофлористических исследований в Высокогорном физико-географическом районе Дагестана. Даны сведения о 15 видах и 3 родах (Immersaria, Montanelia и Porpidia), новых для лихенофлоры республики. Для каждого вида указаны местонахождения и сведения о распространении на Кавказе. Lecidea silacea, Rhizocarpon ridescens, Rh. superficiale впервые приводятся для лихенофлоры Кавказа. Acarospora sulphurata и Rhizocarpon lavatum ранее на Северном Кавказе не были известны. (The highland of Dagestan is very contrasting to the other parts of the Republic. It has specific climatic, geomorphological and lithological features. These features imply a high richness of species. But only 160 species previously were known from the highlands of Dagestan according to the literature and data of our local floristic study. This paper presents data on 15 species and 3 genera (Immersaria, Montanelia, Porpidia) new to Dagestan. The information on their distribution in the Caucasus with data of localities is given. Three species are recorded for the first time in the Caucasus: Lecidea silacea, Rhizocarpon ridescens, Rh. superficiale. For these species, the characteristic features of specimens are given, and the nearest locality is cited. Two species (Acarospora sulphurata, Rhizocarpon lavatum) are new to the Northern Caucasus.)
We have recorded 138 species (125 of them epiphytic/epixylic) in a single preserved lowland forest in Dagestan (Russia), “Samurski” forest at the west coast of the Caspian Sea. Within its 2,000 hectares, some remnants of old-growth forests persist, dominated by Acer campestre, Carpinus betulus and Quercus robur. This mix of tree species is typical of many lowland deciduous forests in Central Europe, and we found that the lichen flora of Samurski also has much in common with those forests, but less in common with other types of Central European forests. Comparison with geographically closer lowland forests in Azerbaijan, Russia and Iran is impossible due to a lack of data. Using Detrended Correspondence Analysis, we defined a group of species diagnostic for temperate lowland deciduous forests; it includes about 20 species recorded in Samurski, most of which are crustose and usually with Trentepohlia as photobiont. In contrast to Central European lowland deciduous forests, the lichen flora of Samurski includes several species known mainly from the oceanic western Caucasus and Western Europe. To enable comparison with “fixed-area” lichen inventories, we have obtained a separate list of 82 lichen species from a detailed survey of a 1 ha plot in one of the best-preserved forest spots in Samurski. Fifty-nine species in 17 genera (Arthothelium, Bactrospora, Bryostigma, Catinaria, Coniocarpon, Cresporhaphis, Dendrographa, Enchylium, Enterographa, Inoderma, Lecanographa, Lepraria, Pachnolepia, Peridiothelia, Sclerophora, Xanthoriicola, Zwackhia) are new to Dagestan. Agonimia flabelliformis, Arthonia exilis, Bacidina auerswaldii, Cresporhaphis wienkampii, Caloplaca raesaenenii, C. tominii, Candelariella superdistans and Verrucaria umbrinula are new to the Greater Caucasus. Agonimia borysthenica, Bacidina adastra and Lecanographa lyncea are new to Russia. Candelariella superdistans is new to Asia.
A taxonomic review of the genus Candelariella in the Caucasus is provided. The genus Candelariella includes approximately 50 species worldwide. Until recently, six years ago, in the first Russian checklist of lichens this genus was represented by 22 species. Only seven species of Candelariella were known from the Northern Caucasus. The Caucasus, however, is a world’s biodiversity hotspot, and this number of species was too low. The number of Candelariella species increased significantly after the start of our intensive floristic studies with new records of C. antennaria, C. efflorescens, C. oleaginescens, C. plumbea, C. rhodax, C. viae-lacteae. In this paper three species (C. faginea, C. rosulans and C. superdistans) are reported new to the Caucasus. Two species (C. medians and C. placodizans) are excluded from the Caucasian lichen flora. Currently there are a total of 16 species of Candelariella in the Caucasus. The most of the species were recorded from Adygeya (10 species), Dagestan (10), Armenia (8) and Krasnodar Region (8). Candelariella commutata, C. efflorescens, C. rhodax are reported for the first time for North Ossetia and Ingushetia, C. lutella - for Dagestan and Ingushetia, C. vitellina - for Ingushetia. This paper aims to contribute to a better understanding of this poorly known genus in the Caucasus, focusing mainly on authors’ collection in different regions of the Northern Caucasus in between 2009 and 2016. A key for the identification of all the Caucasian species (including 8 provisory species) is given. Detailed descriptions, taxonomic remarks, notes on ecology, distribution in the Caucasus and known distribution in the world for each taxon are provided.
Teloschistaceae, one of the largest families of lichenized fungi, has its known Eurasian diversity hot-spots in the Mediterranean basin and in arid continental territories. The Caucasus is a natural boundary between these territories and the diversity of Teloschistaceae is therefore expected to be high in this region. We studied the easternmost part of the Caucasus, Dagestan, a region neglected by lichenologists in the past, but with recent lichenological activity. We provide here a checklist of 85 species of Teloschistaceae, 39 of them new to Dagestan from our field work in 2015, and four species new to Russia (Athallia nesodes, "Caloplaca" emilii, "Caloplaca" xerica and Gyalolechia epiphyta). This total is higher than the numbers known from some well-surveyed Central European countries, but lower than numbers reported from Mediterranean countries. It suggests a rather high diversity of Teloschistaceae in Dagestan, although the absence of well-developed maritime and Mediterranean habitats (which are usually rich in species of Teloschistaceae) precludes an even higher diversity.
The lichen fl ora of the Tlyaratinski y Protected Area (Zakaznik) in Dagestan, North-Eastern Caucasus is surveyed. In total 165 species, including 162 lichenized and 3 lichenicolous fungi, representing 82 genera are listed here with their localities and substrates. Caloplaca diphyodes is new to the Russian Caucasus. Arthonia intexta, Bryoria smithii, Protoparmelia badia and Sphaerellothecium reticulatum are new to Dagestan. Two species (Tornabea scutellifera, Usnea fl orida) represent those listed in the Red Data Book of Russia. The territory of Tlyaratinskiy Protected Area is the only known locality in the Caucasus of the species Carbonea assimilis, Lecidea silacea, Rhizocarpon ridescens and R. superficiale.
Twenty-three species of lichens and five lichenicolous fungi are reported for the first time for Dagestan. Of them, Bellemerella polysporinae, Lecanora pannonica, Opegrapha lutulenta, Porpidinia tumidula and Verrucaria praerupta are new to Caucasus and Russia; Lecanora contractula, Strangospora deplanata and Tremella candelariellae are reported for the first time from Caucasus. Opegrapha lutulenta and Tremella candelariellae are new to Asia. The genera Bellemerella, Didymocyrtis, Leprocaulon, Porpidinia, Protoparmelia, Strangospora and Tremella are reported for the first time from Dagestan. Porpidinia and Bellemerella are genera new to Russia. The most noteworthy records are briefly discussed.
Species diversities and similarities of lichen flora of high-mountain (alpine and subalpine) calcareous habitats from the Western Caucasus (Lagonaki Plateau, Adygeya Republic, Krasnodar Territory) and the Eastern Caucasus (Gunib Plateau, Inner-mountain Dagestan) are compared. Up to date, 452 species in 164 genera and 50 families are known from the the two high-mountain plateaus. There are 141 species, 87 genera and 27 families common for two plateaus. The Lagonaki Plateau at the height 1800-2760 m has 377 species where 236 are specific. The Gunib Plateau at the height 1800-2354 m has 216 species where 75 are specific. The similarities degree of lichen flora between the two plateaus is 31 %. Species of three families Verrucariaceae, Teloschistaceae and Physciaceae compose the lichen flora bullet of two plateaus with gross share above 1/3 of species composition. There are two main groups among revealed lichen species by the pattern of distribution: a) distributed only in highlands (specific highlands) - 190 species in two plateaus; b) prevailing by the height gradient and distributed at the low height (common highlands) - 262 species. The lichen flora specificity increases with the increasing of the height above sea level. The Lagonaki Plateau has 157 mountain species in which 129 are specific. There are also 220 widely used species (108 specific). The Gunib Plateau has 61 mountain species (33 specific) and 115 prevailing species (42 specific). Ground lichen flora species has widely distributed by the height gradient and epilit lichens are limit distributed in high-mountain. The first effect the lichen flora similarity of two plateau largely, the second -there specificity and difference. High proportion of limit distributed and specific mountain epilit lichens shows more self-contained formation of high-mountain lichen component. The high similarity in lichen flora of the plateaus is caused by similarities in calcareous habitats of interlay material - calcarous rock. However the difference of climatic parameters especially in average annual precipitation (the Lagonaki Plateau has about 2000 mm elements in a year; Gunib -620 mm) caused the presence of differential taxons in the lichen flora. Arid and thermophilic lichens from Siberian-Asian, Irano-Turanian and sub-Mediterranean species occur in the Gunib Plateau only. Those are namely in genera Aspicilia, Flavoplaca, Glypholecia, Gyalolechia, Neocatapyrenium, Peltula, Thallinocarpon, Thyrea, Xanthoparmelia. On the other hand, humid and cryophilous lichens (atlantic, central and northern Europe are only known from the Lagonaki Plateau; most of Arthrorhaphidaceae, Hymeneliaceae, Lecideaceae, Pannariaceae, Protothelenellaceae, Thelenellaceae, Thelocarpaceae, Verrucariaceae, etc., and genera Bacidia, Lecanora, Ochrolechia, Polysporina, Porpidia, Scytinium, Tetramelas, etc.
Data on the lichen flora diversity of the Northern Caucasus have been collected in the framework of the project “North Caucasian Lichen Flora” (NCLF) (grant RFBR no 15-29-02396). The Caucasus Mountains are one of the world's biodiversity hotspots as well as one of the richest regions of Russia. About only 1100 species have been mentioned for NC in the first Russian lichen checklist (2010). As a result of intensive studies in latest years, the number of known species has increased by more 500 new species.
Samur forest is the only Russian subtropical Liana forest situated in the lowland at the western shore of the Caspian Sea. Its territory of 11200 ha is protected. Dominant tree species are Carpinus betulus and Querqus robur. We have explored virgin and old-growth core of the forest and also some marginal sites with a coastal shrub vegetation. We have recorded about 116 species of epiphytic (and epixylic) lichens and allied non-lichenized fungi, but only 20% are macrolichens. Our record list includes new species and genera for Dagestan and Caucasus Mts. Some species are new to Russia, e.g. Agonimia borysthenica and Lecanographa lyncea. We consider some of our records as rare and endangered lichens indicating old-growth lowland forest remnants, e.g.
