“…The loci choice was based on the availability of sequences from these studies and considerations on marker variability. For example, the nuclear ribosomal ITS region was not included (following Bonfim Santos & Stech, 2017b) since the internal transcribed spacers are largely unalignable at family and suprafamilial levels in the Dicranidae.…”

Haplolepideous moss systematics has been through major changes based on morpho-molecular studies. However, many taxa remain little studied with still unclear circumscriptions and relationships among the traditionally recognized families. We inferred the phylogenetic relationships of the haplolepideous mosses based on a sample of 37 out of the 38 haplolepideous moss families and using mitochondrial (nad5 G1 intron) and chloroplast (trnS-rps4 spacer/rps4 gene and trnL gene/trnL-trnF spacer) markers. The resolved relationships indicate the need for rearrangements in the circumscription of the Aongstroemiaceae and Dicranellaceae and their genera, which correspond to the variation of morphological characters of leaf shape, rhizoid tuber morphology, and capsule and peristome traits. The two families, although historically considered morphologically close, were resolved as separate lineages in the core haplolepideous clade. The genera Aongstroemia and Dicranella were resolved as polyphyletic across the clades corresponding to the families Aongstroemiaceae and Dicranellaceae and other clades. The characterization of Aongstroemia by julaceous plants is not supported; the three species sampled here belong in three separate families and differ from one another in other (more stable) characters, such as the presence and shape of peristome teeth. Regarding Dicranella, the sampling of 13 of its 167 species suggests the broad morphological variation comprised by the genus under its current circumscription might be narrowed down to smaller ranges corresponding to the phylogenetically separate clades. The present molecular data furthermore suggest changes in the composition of the protohaplolepideous Dicranidae grade, including one Dicranella clade, a new lineage with a ditrichoid morphology, but excluding the Chrysoblastellaceae, which were resolved in the core haplolepideous clade. The latter finding implies the independent evolution of the rare double-opposite peristome type in both the protohaplolepideous grade and the core haplolepideous clade.

“…Similar to many moss genera, the moss genus Leucobryum Hampe has been shown to include several cryptic species ( Oguri et al 2006 ; Oguri et al 2010 ; Oguri et al 2013 ; Bonfim Santos and Stech 2017 ). The genus currently includes about 80–100 species worldwide with predominantly temperate and tropical distribution ( Eddy 1990 ; Enroth 1990 ; Klazenga 2012 ).…”

Leucobryum scalare was described in 1904 but its taxonomic status has been disputed, being reduced to a variety of Leucobryum aduncum or synonymized with Leucobryum aduncum. The taxonomic confusion of this taxon has remained unresolved. Hence, we revisited the taxonomic status of the taxon using phylogenetic and morphometric approaches. A total of 27 samples from Leucobryum aduncum var. aduncum and Leucobryum aduncum var. scalare were used to generate data from four markers, including ITS1, ITS2, atpB-rbcL spacer, and trnL-trnF. The concatenated dataset was used to reconstruct a phylogenetic tree. Both qualitative and quantitative morphological characters were measured and analyzed with Principal Component Analysis (PCA) and PERMANOVA. The results showed that the two taxa are closely related but they are reciprocally monophyletic. Both qualitative and quantitative characters could also separate Leucobryum aduncum var. scalare from Leucobryum aduncum var. aduncum as shown with PCA and PERMANOVA. We propose the resurrection of the species rank for Leucobryum scalare as separate from Leucobryum aduncum. This work highlights the need for a more thorough revision of Leucobryum to clarify the actual level of diversity in this genus.

The genus Campylopus in Russia is revisited based on molecular phylogenetic data, which included also European accessions originated from vicinities of the loci classici of several species. Eight species are proved to occur in Russia, among which C. schimperi is widespread in montane areas throughout the country, while other species are known from few localities in Kamchatka (5 species), southern part of Russian Far East (3 species), Caucasus (3 species) and Kaliningrad Province (1-3 species). Nuclear ITS allowed a reasonable delimitation of C. schimperi and C. subulatus; previously known differences in their morphology, ecology and distribution are confirmed. Molecular phylogenetic reconstruction, based on combined plastid trnS-trnF, mitochondrial Nad5 and nuclear ITS suggests that the genus Campylopus harbours at least three well morphologically and phylogenetically justified lineages, which could be considered as separate genera to prevent assigning Pilopogon to synonymy of Campylopus. РезюмеПроведена ревизия рода Campylopus в России с помощью молекулярно-филогенетических методов, в которой были использованы для сравнения данные по образцам из Европы, собранным вблизи loci classici нескольких видов. На территории России выявлено 8 видов, среди которых наиболее широко распространенным является C. schimperi, встречающийся в горных регионах по всей стране, в то время как остальные виды известны из немногочисленных местонахождений на Камчатке (5 видов), в южной части российского Дальнего Востока (3 вида), на Кавказе (3 вида) и в Калининградской области (1-3 вида). Ядерный участок ITS позволил хорошо разграничить C. schimperi и C. subulatus и подтвердить ранее известные отличия между ними в морфологии, экологии и распространении. Молекулярно-филогенетическая реконструкция, основанная на объединенных последовательностях пластидного trnS-trnF, митохондриального Nad5 и ядерного ITS маркеров позволяет предположить, что в роде Campylopus имеются по меньшей мере три морфологически и филогенетически хорошо разграниченные линии, которые могут быть выделены в качестве самостоятельных родов, чтобы избежать включения рода Pilopogon в синонимы Campylopus.
