Introduction
The Republic of Tuva is one of the largest republics in Russia. It extends from north to south between 53°43'N and 49°47'N and borders Mongolia to the South. It is between 88°47'E and 99°16'E in longitude and borders the Republic of Altai in the West and the Republic of Buryatia in the East. The
territory is geomorphologically heterogeneous: vast intermountain basins combine with ridges and plateaus. The highest point is Mongun-Taiga Mts -3976 m a. s. l. The Republic of Tuva is characterized by an increased continental climate compared with the adjoining regions of Siberia. South Tuva Mountains are the watershed between the river basin of the Arctic Ocean and the drainless region

of Central Asia. This watershed is the southern limit for the Siberian taiga landscapes and the northern one for the desert-steppe landscapes of Mongolia. In phytogeography terms, the mountain range of southern Tuva marks the border of the Boreal and ancient Mediterranean floristic sub-kingdoms of the Holarctic (Takhtajan, 1986).
It is surprising, but today the Republic of Tuva is one of the biggest bryological "white spot" of Russia. For this vast and heterogeneous territory, there is the only one list of local bryoflora, for the Todzha Valley (Otnyukova, 2003). Additionally, for some species it is possible to find information about their locations in the territory (Bardunov, 1972, 1974). To fill the gap some keyplots were investigated recently and about 50 species were revealed as new for the territory immediately, among them so interesting as Amblyodon dealbatus (Hedw.) P. Beauv., Catoscopium nigritum (Hedw.) Brid., Tortella spitsbergensis (Bizot et Ther.) O. Werner, Kockinger et Ros and others (Pisarenko, 2013, 2018; Pisarenko, Artemov, 2019); and also species from the Red Data Book of the Russian Federation - Aongstroemia julacea (Hook.) Mitt. (Bardunov, 2008), Hilpertia velenovskyi (Schiffn.) R. H. Zander. (Czernyadjeva et al., 2008). The paper continues the list of new findings.
Materials and methods
The work is based on the materials of the author collected in 2013 and 2018-2019. The specimens examined are deposited in the Central Siberian Botanical Garden (NSK), duplicates are in the herbariums of the Altai State University (ALTB) and Moscow State University (MW). The location coordinates are determined using a 12-channel GPS and are given in decimal degrees. The names of moss species are mainly according to the "Check-list of mosses of East Europe and North Asia (Ignatov et al., 2006); names of vascular plants are according to the "Check-list of the flora of Asian Russia" (Konspekt flory ..., 2012).
Species new for the Republic of Tuva
Calliergon richardsonii (Mitt.) Kindb.
Specimens examined: "Russia, the Republic of Tuva, Mongun-Taiga Distr., Chikhacheva Range, N-faced macroslope, Chedi-Tey River headwaters, 2395 m. 50°13'26.69"N, 89°25'10.78"E, sedge-moss swamp along the periphery of small lake, in admixture with Scorpidium cossonii (Schimp.)
Hedenas. 22 VII 2019. O. Pisarenko. NSK2007842" (NSK, ALTB); "Russia, the Republic of Tuva, Mongun-Taiga Distr., near Khindigtik-Khol Lake, 2296 m. 50°23'50.75"N, 89°58'50.2"E, gentle slightly concave slope, mire community with predominance of Betula rotundifolia Spach, Eriophorum vaginatum L. and Aulacomnium palustre (Hedw.) Schwagr. 2 VIII 2019. O. Pisarenko. NSK2007870" (NSK).
Calliergon richardsonii is obligate swamp species. It is distributed mainly in the arctic and subarctic zones; in the boreal zone it is known from a few localities (Lapshina, 2003; Ignatov, Ignatova, 2004); in south it rarely occurs in the mountains from South Europe (Hodgetts, 2015) to Caucasus (Ignatov, Ignatova, 2004) and Mongolia (Tsegmed, 2010). In Altai-Sayan region the species is rare; there are a few records for Altai (Ignatov, 1994), for Khakassia and for the ranges of the West and East Sayan within the Krasnoyarsk Territory and the Irkutsk Province (Bardunov, 1974).
Coscinodon cribrosus (Hedw.) Spruce
Specimens examined: "Russia, the Republic of Tuva, Mongun-Taiga Distr., Kargy River valley downstream of Mugur-Aksy settlement, 1650 m. 50°17'7.8"N, 90°39'29.52"E, steep N-faced rock outcrops, on stones. 8 VIII 2019. O. Pisarenko. NSK2008043, S+" (NSK, ALTB).
The species prefers xeric habitats and has wide but disjunctive distribution in the Holarctic. In Russia it is known from scattered localities from Kola Peninsula to South Kuril Islands by way of the Caucasus, Transbaikalia, Yakutia and Kamchatka (Ignatov et al., 2017; Herbarium specimens of Russian mosses, URL: http://arctoa.ru/Flora/basa. php). The species is distributed in many regions of Mongolia (Tsegmed, 2010), but in Altai-Sayan region it was reported only from Altai Mts (Ignatov, 1994).
Hymenostylium recurvirostrum (Hedw.) Dixon
Specimens examined: "Russia, the Republic of Tuva, Erzin Distr., Sangilen highlands, the upper reaches of the Naryn river, 1913 m. 50°13'31.94"N, 96°16'56.86"E, limestone outcrops in a shallow gully. 12 VII 2013. O. Pisarenko. NSK2007134" (NSK, ALTB); "Russia, the Republic of Tuva, Erzin Distr., Sangilen highlands, the upper reaches of the Balyktyg-Khem river, 2230 m. 50°18'56.52"N, 96°27'44.28"E, foot of N-faced slope, on stones in Betula rotundifolia Spach thickets. 17 VII 2013. O. Pisarenko. NSK2007135" (NSK).
Pisarenko O. Yu. New moss records from the Republic of Tuva
The species is widely distributed in most areas of the Holarctic. It occurs mainly in the mountains and grows on wet rocks, more often on limestone. In Siberia it reaches the high Arctic: is known from the Taimyr Peninsula, from the Yakut Arctic, and from the Novosibirsk Islands. But it is more common in the mountains of the southern part of the territory -in the Altai, in the Sayan, in the Baikal region (Herbarium specimens of Russian mosses. URL: http://arctoa.ru/Flora/basa.php). It is not rare in Mongolia (Tsegmed, 2010).
Isopterygiopsispulchella (Hedw.) Iwats.
Specimens examined: "Russia, the Republic of Tuva, Erzin Distr., Sangilen highlands, Naryn river valleyvicinity, Naryn settlement, 1320 m. 50°12'7.85"N, 95°36'19.44"E, floodplain forest from Picea obovata Ledeb., on rotten log. 06 VII 2013. O. Pisarenko. NSK2007530" (NSK, ALTB); "Russia, the Republic of Tuva, Bay-Tayga Distr., Kara-Khol Lake surroundings, N-faced slope, 1900 m. 51°20'47.68"N, 89°25'15.71"E, larch-forest, on rotten log. 10 VII 2018. O. Pisarenko. NSK2007362" (NSK).
The species takes place in most regions of the Holarctic. It is more common in regions with cold and cool climates; it is widely distributed from the tundra zone to coniferous and broad-leaved forests and in mountains. It grows on rotten log in forests and in breaks of grass turf on the soil in tundra, in crevices of rock outcrops and in niches of stone fields. It is rare or absent in arid areas. In Siberia, it occurs from the high Arctic to the Altai and Sayan and is more common in mountainous regions. In Mongolian mountains it is also not rare (Tsegmed, 2010).
Loeskypnum badium (Hartm.) H. K. G. Paul
Specimens examined: "Russia, the Republic of Tuva, Bay-Tayga Distr., Kara-Khol Lake vicinity, Caste-Khol Lake shore, 1930 m. 51°26'35.3"N, 89°23'45.31"E, wet community with Betula rotun-difolia predominance, in moss cover, a mixture with Warnstorfia sarmentosa (Wahlenb.) Hedenas. 11 VII 2018. O. Pisarenko. NSK2007374" (NSK, ALTB).
The species is widespread mainly in the Arctic and subarctic regions; to the South it occurs sporadically in the high mountains. It grows in mineralo-trophic mires and in wet tundra. In South Siberia it is rather rare, known from a few localities in southeast Altai and in East Sayan (Herbarium specimens of Russian mosses. URL: http://arctoa.ru/Flora/ basa.php). In Mongolia for the species there is the
only record from the last century (Abramova, Tseg-med 1983).
Plagiobryum demissum (Hook.) Lindb.
Specimens examined: "Russia, the Republic of Tuva, Tes-Khem Distr., East Tannu-Ola Range, Ka-ra-Khol Lake vicinity, Khol-Oozhu River source, 1740 m. 50°54'27.76"N, 94°19'53.76"E, on bare peaty soil along a stream on sunny spot in mountain forest-steppe belt. 30 VI 2018. O. Pisarenko. NSK2007307, S+" (NSK, ALTB).
This arctic-alpine species is rare in Russia and occurs mostly in Siberia, both in Arctic and high mountains; it grows usually in moss-lichen and dryad tundra on soil and gravelly substrates. Plagio-bryum demissum is reported for Republic of Tuva (Ignatov et al., 2018), but the report is wrong. The report based on a sample of Bardunov from the Kadir-Oruk pass. 19 VII 1961 (IRK, MHA); but in South Siberia there are two passes with the name "Kadir-Oruk" - one is on the Tsagan-Shabit Range in Tuva and another is in the Irkutsk Province in the East Sayan; L.V. Bardunov was collecting in the second locality.
Pseudocalliergon turgescens (T. Jensen) Loeske
Specimens examined: "Russia, the Republic of Tuva, Mongun-Taiga Distr., Khindigtik-Khol Lake surroundings, 2426 m. 50°22'4.01"N, 89°58'16.14"E, big mire massif in the intermountain basin, in moss cover of a hollow. 2 VIII 2019.

O. Pisarenko. NSK2004931" (NSK).
Pseudocalliergon turgescens is rather rare arcto-alpine species. It is widely distributed in Arctic and Subarctic regions: in Alaska, Canada, Greenland, Scandinavian Mountains; in Russia - from Kola Peninsula to Chukotka, north to Franz Joseph Land and Vrangel Island (Herbarium specimens of Russian mosses. URL: http://arctoa.ru/Flora/basa.php). Farther south it has scattered localities in mountains. In Altai-Sayan region it is known by some samples from Terektinsky and Kurai Ranges in Altai and from Tunkinskiy, Kitoyskiy and Pogranichnyy Ranges in East Sayan (Bardunov, 1974; Ignatov, 1994). There are reports from Mongolian highlands (Tsegmed, 2010). P turgescens grows in wet habitats - in hollows of mires, near springs and in water of cold lakes. In the Republic of Tuva it is common and dominates in moss cover of highland swamps.
Tayloria lingulata (Dicks.) Lindb.
Specimens examined: "Russia, the Republic of Tuva, Mongun-Taiga Distr., Tsagan-Shabit Range, S-faced macroslope near Uzun-Hem River, elev. 2800 m. 50°28'29.28"N, 90°0'19.8"E, on peaty soil along a crook 7 VIII 2019. O. Pisarenko. NSK2007819, S+" (NSK, ALTB); "Russia, the Republic of Tuva, Mongun-Taiga Distr., Mongun-Taiga Mt., N-faced slope to Mugur River tributary, 2250 m. 50°18'59.22"N, 90°14'37.86"E, wet larch-forest, in moss cover in admixture with Campylium stellatum (Hedw.) C. E. O. Jensen. 31 VII 2019. O. Pisarenko. NSK2007820, S+" (NSK).
The species is distributed in the Arctic and Subarctic and in the highlands of the Northern Hemisphere temperate zone. In Russia it occurs sporadically in the tundra zone and highlands from the Caucasus to Sakhalin and Kamchatka (Ignatov et al., 2018). In Altai-Sayan region it is known from the Kantegirsky, Severo-Chuisky and Big Sayan ranges and Kuznetsk Alatau (Bardunov, 1974; Herbarium specimens of Russian mosses. URL: http://arctoa. ru/Flora/basa.php). There are no reports from Mongolia. The species grows usually in relatively wet, swampy habitats, sometimes along streams.
New records for the species previously known by a single specimen
Fissidens osmundoides Hedw.
Specimens examined: "Russia, the Republic of Tuva, Mongun-Taiga Distr., Chikhacheva Range, N-faced macroslope, Chedi-Tey River headwaters, 2395 m. 50°13'26.69"N, 89°25'10.78"E, sedge-moss swamp along the periphery of small lake, in admixture with Meesia uliginosa Hedw. 22 VII 2019. O. Pisarenko. NSK2007811" (NSK, ALTB); "Russia, the Republic of Tuva, Mongun-Taiga Distr., Mongun-Taiga Mt, N-faced slope to Mugur River valley, 2914 m. 50°17'52.94"N, 90°12'56.7"E, golt-sy terrace, wet sedge-cobresian tundra, in admixture with Meesia uliginosa. 31 VII 2019. O. Pisarenko. NSK2007828" (NSK). Fissidens osmundoides is widely distributed in the Holarctic, it is found in most parts of the Arctic and boreal zone; further South it grows in the mountains, penetrating to the tropical regions of South- East Asia and the southern States of America; there are reports from the southernmost tip of the South American mainland (Krajewski, 2017). In Altai-Sayan region the species is not rare in Altai and Kuznetsk Alatau (Herbarium specimens of Russian mosses. URL: http://arctoa.ru/Flora/ basa.php); it occurs in Salair and reported for ranges Oyskiy, Kantegirskiy, Yergak-Targak-Tayga in the Western Sayan Mountains and Tunkinskiy Ridge in the Eastern Sayan (Bardunov, 1974). The locality in Yergak-Targak-Tayga Range is specified as "Sistig-Khem River headwaters" (Bardunov, 1974), so it refers to the Republic of Tuva and located the northeast of the territory. That was the only report of the species for the Republic. There are no records of the species from Mongolia.
Indusiella thianschanica Broth. et Müll. Hal.
Specimens examined: "Russia, the Republic of Tuva, Mongun-Taiga Distr., Tsagan-Shabitu Range, Barlyk River near Aldig-Khem Creek mouth, 2190 m. 50°26'10.43"N, 90°41'57.84"E, E-aspect steep steppe slope, large vertical outcrops of shale, in fissures, associated with Distichium capillaceum (Hedw.)

Pisarenko O. Yu. New moss records from the Republic of Tuva
Indusiella thianschanica has disjunctive distribution in arid regions of the Northern Hemisphere: in the Pamirs and Tien Shan, in Tibet, in Mongolia and Siberia. Reported from the Caucasus, from Lake Chad in Africa, from Alaska, Bolivia and Argentina. In Siberia the species is very rare and known from scattered localities in Altai-Sayan region, in the Baikal region, in Yakutia and Taimyr. It grows on dry rocks, on the denudated surface of stones and in small crevices. I. thianschanica is in the Red Data Book of the Russian Federation (Dudareva et al., 2008) also in the Red Data Books of number regions of South Siberia including the Republic of Tuva (Pisarenko, Bakalin, 2018). In Tuva for a long time the species was known only by collection of L. V. Bardunov (11 VIII 1968) from Bert-Dag surroundings, East Tannu-Ola Range.
Pseudocalliergon trifarium (F. Weber et D. Mohr) Loeske
Specimens examined: "Russia, the Republic of Tuva, Mongun-Taiga Distr., Chikhacheva Range, N-faced macroslope, Chedi-Tey River headwaters, 2395 m. 50°13'26.69"N, 89°25'10.78"E, sedge-moss swamp along the periphery of small lake. 22 VII 2019. O. Pisarenko. NSK2007839" (NSK, ALTB); "Russia, the Republic of Tuva, Bay-Tayga Distr., Kara-Khol Lake vicinity, Caste-Khol River headwaters, 1927 m. 51°25'21.68"N, 89°24'27.11"E, big mire massif in the intermountain basin, in moss cover in admixture with Scorpidium revolvens (Sw. ex anon.) Rubers and Sphagnum platyphyllum (Lindb. ex Braithw.) Warnst. 11 VII
2018. O. Pisarenko. NSK2007517" (NSK); "Russia, the Republic of Tuva, Mongun-Taiga Distr., Mongun-Taiga Mt., S-faced macroslope, interfluve of the Orta-Shegetay and Tolayty rivers, 2850 m. 50°9'25.6"N, 90°4'59.63"E, flat bottom of stream valley, sedge mire, in moss cover in admixture with Warnstorfia sarmentosa. 28 VII 2019. O. Pisarenko. NSK2007861" (NSK).
Pseudocalliergon trifarium is distributed in the Holarctic, mainly in the northern regions and in the highlands. It grows in swamps rich in mineral nutrition, often in places of groundwater outlets with a high content of carbonates. In Siberia it is rare. In the West Siberian plain it penetrates south to the southern part of the Great Vasyugan mire; in Altai-Sayan region it is known from a few scattered localities in Altai, Kuznetsk Alatau and Salair (Igna-tov, 1994; Pisarenko, 2014). In Republic of Tuva the species first time was recently reported from Sang-ilen (Pisarenko, 2013); according to new data it is rather constant component of moss cover in Tuva highland mires.
Newly revealed species are different in ecology and area; they belong to different geographical elements. That confirms the thesis of bryological knowledge deficiency for the Republic of Tuva and the need to continue research.
