Abstract: DNA-barcoding revealed/confirmed the range extension of the following bryophytes: Campylostelium saxicola (Krasnodar Territory), Tortella densa (Yakutia), T. fasciculata (Crimea), T. pseudofragilis (Kamchatsky Territory), T. angustifolia (Adygea Republic), and Apopellia megaspora (Murmansk Province). РезюмеС помощью ДНК-баркодинга выявлены или подтверждены находки за пределами основного ареала следующих видов мохообразных: Campylostelium saxicola (Краснодарский край), Tortella densa (Якутия), T. fasciculata (К… Show more

Leskea catenulata subsp. remotifolia was described in 1877 based on specimens from Georgia (Caucasus) and later never reported from this country. It was recently found that this taxon is identical with the Hyrcanian species traditionally called Pseudoleskeella laxiramea. It was recently placed into Forsstroemia or Leptodon. In 2022 the species was again collected in Georgia, in a locality 15 km from the locus classicus. It appeared to be identical to the Iranian specimens in its ITS sequences. However, in the molecular phylogenetic tree based on ITS it is resolved in a clade with Cryptoleptodon pluvinii, whereas Leptodon smithii, L. longisetus, and L. corsicus form a clade sister to Cryptoleptodon. Since the representatives of these two clades possess considerable morphological distinctions, we suggest to consider Cryptoleptodon as a separate genus. This conclusion is also supported by the statistical support of each clade (Leptodon and Cryptoleptodon) which higher than the support of their common clade, both from Bayesian and maximum parsimony analyses. РезюмеОписанную из Грузии по сборам 1877 года Leskea catenulata subsp. remotifolia с тех пор более в стране на находили. Недавние исследования выявили ее таксономическую идентичность с ирано-гирканским видом, традиционно называвшимся Pseudoleskeella laxiramea. Последние работы относили его к другим родам, а именно или к Forsstroemia, или к Leptodon. В 2022 году вид был повторно собран в Грузии, к 15 км от locus classicus. По последовательностям ITS он оказался полностью идентичным иранским растениям. Вместе с тем, в молекулярно-филогенетическом дереве по последовательностям ITS он оказывается в кладе с Cryptoleptodon pluvinii, тогда как Leptodon smithii, L. longisetus и L. corsicus образуют сестринскую кладу. Ввиду того, что виды этих клад значительно отличаются морфологически, мы предлагаем считать Cryptoleptodon отдельным родом. Этот вывод поддерживается и тем, что статистические поддержки обеих клад, Leptodon и Cryptoleptodon, значительно выше, чем поддержка их совместной клады и в Байесовом анализе, и в анализе методом максимальной парсимонии.

Despite ongoing moss flora research in the Russian Far East, the bryoflora of Koryakia remains relatively poorly studied. A brief excursion to Karaginskii Island in August 2023 revealed 112 bryophyte species. With the previously published data and our additions, the total number of moss species on the island is 141. We identified 36 species that are new to the "Southern Koryakia" region of the northern Russian Far East. The most interesting findings are Brachythecium frigidum, Bucklandiella macounii subsp. alpina, and Ditrichum zonatum, previously known in the north of the Far East only from the Commander Islands, as well as a rare and little-studied species Tortella pseudofragilis. Our record of Bryoerythrophyllum rubrum is the first for Kamchatka. РезюмеНесмотря на продолжающиеся активные исследования флоры мхов Дальнего Востока России, бриофлора Корякии остается слабо изученной. Краткосрочная экскурсия на остров Карагинский позволила выявить 112 видов мхов. С учетом наших дополнений к списку 2012-го года на острове произрастает 141 вида мхов. Среди выявленных мхов 36 видов являются новыми для района «южная Корякия» севера Дальнего Востока России. Наиболее интересные находки -это ранее известные на севере Дальнего Востока только с Командорских островов Brachythecium frigidum, Bucklandiella macounii subsp. alpina и Ditrichum zonatum, а также редкий и малоизученный вид Tortella pseudofragilis. Наша находка Bryoerythrophyllum rubrum -первая для Камчатского края.
