Buck & Crum., Andreaea alpestris (Thed.) Schimp., and Andreaea mutabilis Hook.f. & Wilson are newly recorded in Türkiye and Southwest Asia, following a recent bryological survey in the Artvin region. Additionally, the genus Iwatsukiella W.R.Buck & H.A.Crum. has been introduced as a new record for Türkiye’s bryophyte flora. This study provides brief descriptions, illustrations, and data on the geographic distribution and ecological preferences of these species, along with comparisons to morphologically similar species. RÉSUMÉ Trois espèces remarquables de mousses inédites en Turquie et en Asie du Sud-Ouest. Iwatsukiella leucotricha (Mitt.) Buck & Crum., Andreaea alpestris (Thed.) Schimp. et Andreaea mutabilis Hook.f. & Wilson ont été récemment répertoriées en Turquie et en Asie du Sud-Ouest, à la suite d’une étude bryologique menée récemment dans la région d’Artvin. De plus, le genre Iwatsukiella W.R.Buck & H.A.Crum. a été introduit comme nouveau genre dans la flore bryophyte de Turquie. Cette étude fournit de brèves descriptions, des illustrations et des données sur la répartition géographique et les préférences écologiques de ces espèces, ainsi que des comparaisons avec des espèces morphologiquement similaires.

INTRODUCTION The Karçal Mountains, a range extending from the Çoruh Valley to the Georgian border, rise from an altitude of 500 m to a peak of 3 545 m a.s.l. (Fig. 1). The region exhibits diverse climatic influences: the Çoruh Valley experiences a sub-Mediterranean climate, while the northern slopes of the Karçal Mountains are influenced by the Black Sea climate. In contrast, the southern slopes experience a mix of subMediterranean and continental climates, shaped by the valley’s influence. The eastern and higher elevations of the range are characterized by a more pronounced continental climate (Eminağaoğlu 2015; Fig. 1). Studies on the bryophyte flora in Türkiye have predominantly focused on the Aegean, Mediterranean, Central Anatolia, Marmara, and Black Sea regions. Although some research has investigated bryophytes in Artvin province and its surrounding areas (Gökler & Öztürk 1992; Townsend 2005; Özdemir et al. 2008; Batan & Özdemir 2008, 2012, 2013a, b; Blockeel et al. 2009; Batan et al. 2014; Alataş et al. 2018), there remains a notable scarcity of studies specifically investigating the bryophyte flora of the Karçal Mountains. The research area encompasses three distinct vegetation types: forest, subalpine, and alpine zones. The dominant vegetation is forest, characterized by mixed woodlands primarily composed of Abies nordmanniana (Steven) Spach subsp. nordmanniana, Picea orientalis (L.) Link, Ulmus glabra Mill., Castanea sativa Mill., Fagus orientalis Lipsky, Quercus petraea subsp. iberica (Steven ex M.Bieb.) Krassiln., Alnus glutinosa (L.) Gaertn, Populus tremula L., Salix caucasica Andersson, Carpinus betulus L., Corylus avellana L., Rhododendron luteum Sweet, R. ponticum L., Prunus laurocerasus L., Rubus platyphyllos C. Koch., Crataegus microphylla K. Koch., C. monogyna subsp. monogyna Jacq., Ilex colchica Pojark., Acer campestre var. campestre L. and Fraxinus angustifolia subsp. oxycarpa (M. Bieb. ex Willd.) Franco & Rocha Afonso (Eminağaoğlu 2015; Yılmaz 2016). MATERIAL AND METHODS In 2022, c. 7500 bryophyte samples were collected from various localities across different habitats and substrates in the Karçal Mountains. The UTM WGS84 coordinate system was used to record the coordinates of each collection site. The moss samples were examined using both stereomicroscope and light microscope, and species identification was conducted by consulting key bryological references (Murray 1988; Noguchi et al. 1991; Gao & Crosby 1999; Wu et al. 2002; Smith 2004; Frey et al. 2006; Brugués et al. 2007; fig. 1. — Location of research area.

Subsp. nordmanniana on the İrsa Plateau, Karçal Mountains, in the Artvin region. dıStrıbutıoN. — Iwatsukiella leucotricha is distributed across Europe (notably in the European part of Russia); Asia (including Georgia, China, and Japan); and North America (in Canada, Alaska, and Oregon) (Ignatov et al. 2006; Hodgetts & Lockhart 2020; GBIF 2024: https://www.gbif.org/species/2681265). This record demonstrates that the Iwatsukiella leucotricha, previously known from North America and eastern Asia, has extended its distribution further within Asia, marking a new location. The majority of records for Iwatsukiella leucotricha are from Russia. In the European part of Russia, it has been documented in the Republic of Bashkortostan (Bashkiria) and the Perm Territory. In Asiatic Russia, occurrences span across numerous regions, including the Chukotka Autonomous Area, Khanty-Mansi Autonomous AreaYugra, Republic of Sakha (Yakutia), Magadan Region, Irkutsk Region, Khabarovsk Territory, Kamchatka Territory, Commander Islands, Republic of Altai, Kemerovo Region, Republic of Buryatia, Trans-Baikal Territory, Amur Region, Primorye Territory, and Sakhalin Region (encompassing Sakhalin Island and the Kuril Islands). (Ignatov 1994; Ignatova et al. 1995, 1996, 2013; Ignatov et al. 2001; Czernyadjeva & Potemkin 2003; Zolotov & Baisheva 2003; Bakalın et al. 2009a; b; Pisarenko 2014; Fedosov et al. 2016; Afonina et al. 2018; Pisarenko & Bakalin 2018; Dudov et al. 2018; Pisarenko et al. 2022). This new record represents the westernmost and southernmost points of Iwatsukiella leucotricha’s global distribution. Additionally, this locality establishes it as both the southernmost occurrence of the species worldwide and the closest point to Europe within its distribution range. deScrıptıoN Plants small, slender 0.7-1.7 cm high, pale to yellowish-green. Stem creeping, densely pinnately branched. Brach 1-4 mm high and densely leaved. Leaves reflexed when moist and imbricate when dry. Leaves 1-2 mm tall and 0.2-1.3 mm wide, rounded or rounded ovate at base, and long, clear, hairpoint on the tip. Alar cells not clearly differentiated. Median leaf cells oblong or rhomboidal. Costa absent, or short and double. Iwatsukiella leucotricha bears resemblance to Habrodon perpusillus (De Not.) Lindb., yet it can be differentiated by its long, transparent hairpoint at the leaf tip and its undifferentiated alar cells. Iwatsukiella leucotricha is also morphologically close to Heterocladiella dimorpha (Brid.) Ignatov & Fedosov, from which it is distinguished by similar features: a long, clear hairpoint at the leaf tip and undifferentiated alar cells. Additionally, Heterocladiella dimorpha differs by its denticulate leaf margins and papillose cell surfaces, further setting it apart from Iwatsukiella leucotricha. remarkS Iwatsukiella leucotricha was most recently assessed for the IUCN Red List of Threatened Species in 2017, where it is categorized as Least Concern (LC) (Baisheva et al. 2019. This assessment, documented under the Europe region, is accessible in the IUCN Red List of Threatened Species (2019: e.T87468107A87758253), with data available as of March 26, 2024.

N. Batan, H. Erata, N. Batan, H. Erata, KTUB[KTUB1627]; duplicate in Erata 1216 (Herb. Erata). ecology. — Andreaea alpestris typically grows on periodically wet rocks and lithosols often near snow beds. Also grows on rocks in subalpine and alpine habitats (Dierßen 2001; Smith 2004; Frey et al. 2006). dıStrıbutıoN. — Andreaea alpestris has a broad distribution, found in Europe (Finland, Norway, Sweden, Great Britain, Andorra, Corsica, France, Italy, Madeira, Spain, Austria, Poland, Switzerland, Bulgaria, North Macedonia, Romania, Caucasus (in Europe); Artict Russia (NW Russia); Ukranie; Asia (China); America (Subartic America, EW America, Canada, Guatemala, Honduras, Costa Rica); (Murray 1988; Allen 1994; Smith 2004; Hodgetts & Lockhart 2020). deScrıptıoN Plants small, 1.0-3.4 cm high, reddish black, black or greenish brown cushions. Shoots 1.4-1.8 cm high. Leaves 0.4-0.8 mm long, usually straight, imbricate, lanceolate, widest above the base. Leaf margins entire, plane or slightly incurved. Costa absent; basal cells short rectangular. Upper cells of leaf almost quadrate. Papillae on the dorsal surface of the leaves low or absent. Perichaetial leaves differentiated, sheathing, convolute and 1.1-1 mm long and 0.5-0.6 mm wide (Murray 1988; Smith 2004; Frey et al. 2006). This species closely resembles Andreaea rupestris Hedw., but it differs by having straight leaves and low or absent papillae on the dorsal leaf surface. Additionally, A. alpestris is distinct from A. rupestris due to its smaller, imbricate, obtuse leaves and the non-porose nature of the upper leaf cells. Andreaea alpestris also bears similarities to Andreaea mutabilis Hook.f. & Wilson; however, it can be differentiated by its typically straight leaves and the low or absent papillae on the leaf surface (Murray 1988; Smith 2004; Frey et al. 2006; Zander 2007). remarkS The species was last assessed for the IUCN Red List in 2017 and is currently classified as Data Deficient (DD) (Hallingbäck et al. 2019; IUCN Red List of Threatened Species, 2019: e.T83659776A87832177, accessed on July 8, 2024). Family aNdreaeaceae Dumort. Genus Andreaea Hedw. *Andreaea mutabilis Hook.f. & Wilson (Fig. 4) SpecımeN examıNed. — Türkiye • Artvin province, Borçka district, Balcıköy Plateau, power plant surroundings on rock; 2095-2150 m alt.; 41°56’36.2”N, 41°20’35.7”E; 22.VI.2022 • Borçka district, Beyazsu Plateau, on rock; 2356 m alt.; 41°57’36.1”N, 41°21’18.4”E; 57 Three remarkable moss species new to Türkiye and Southwest Asia CRYPTOGAMIE, BRYOLOGIE • 2025 • 46 (6) 23.VI.2022; leg. N. Batan, H. Erata, det N. Batan, H. Erata, KTUB[KTUB1628]; duplicate in Erata 1217 (Herb. Erata). ecology. — Andreaea mutabilis typically grows on dry to wet, exposed acidic rocks, It is also found on periodically wet acid boulders crags or rubble, rarely on thin soil over rocks (Dierßen 2001; Smith 2004; Frey et al. 2006). dıStrıbutıoN. — Andreaea mutabilis is distributed across various regions, including Europe (Fareo Islands, Great Britain, Andorra, France, Spain); Asia (Taiwan, China, and Malaysia); the Americas (North and South America); Oceania (New Guinea, Australia, Tasmania, and New Zealand). (Chiang 1998; Gao & Crosby 1999; Smith 2004; Hodgetts & Lockhart 2020). deScrıptıoN Plants small, 1.0-1.2 cm high, reddish to black cushions. Shoots 0.4-1 cm high. Leaves 0.4-0.7 mm long, erect-spreading and straight, lanceolate, widest above the base, acuminate to acute apex. Costa absent. Leaf margins entire, incurved. Basal laminal cells rectangular, basal marginal cells isodiametric, median laminal cells rounded-quadrate or rhomboid. Perichaetial leaves oblong-lingulate, acuminate (Murray 1988; Smith 2004; Frey et al. 2006). Andreaea mutabilis closely resembles Andreaea sinuosa B.M. Murray but can be distinguished by its quadrate basal laminal cells and non-sinuose basal cells. Additionally, A. mutabilis differs from Andreaea rupestris Hedw. by having isodiametric basal marginal cells, less pitted basal cell walls, and quadrate basal laminal cells, whereas A. rupestris has rectangular basal laminal cells and laminal papillae. Andreaea mutabilis also bears similarity to Andreaea alpestris, but differs in its minimally sheathing leaf bases, often displaying a patch of yellow cells at the base, with basal cells that are scarcely pitted. Its basal laminal cells are rectangular, and marginal cells are quadrate, measuring 0.8-1 mm in length and 0.3-0.4 mm in width (Chiang 1998; Murray 1988; Smith 2004; Frey et al. 2006; Zander 2007). remarkS Andreaea mutabilis was last assessed for The IUCN Red List of Threatened Species in 2016, where it is classified as Least Concern (LC) (Hodgetts et al. 2019; The IUCN Red List of Threatened Species 2019: e.T83659827A87792052 accessed on 11 July 2024). CONCLUSION The discovery of Iwatsukiella leucotricha, Andreaea alpestris, and Andreaea mutabilis in the Karçal Mountains extends the known distribution of these species and represents the first records for Türkiye and Southwest Asia. These findings highlight the biogeographical importance of the Karçal Mountains (Artvin, Türkiye), a poorly explored region with high potential for cryptogamic flora. The area emerges as an important reservoir of bryophyte diversity. Continued floristic surveys in this and other under-investigated regions are likely to yield additional noteworthy records, thereby enhancing our understanding of regional moss diversity.
