ABSTRACT Introduction The diversity of the moss genus Glyphomitrium Brid. is concentrated in East Asia. Its range extends to the southern part of the Russian Far East, where its species are rather widespread in hemiboreal coniferous forests. However, the species to which Russian specimens should be assigned remains unclear. Methods A morphological survey was conducted, along with a molecular phylogenetic study based on the plastid trnS–trnF and nuclear ITS regions. Of the three lineages identified, two were investigated using species distribution modelling. Key results For two of three revealed lineages, the use of the names Glyphomitrium crispifolium Nog. (previously considered to be a rare Japanese endemiс) and G. humillimum (Mitt.) Card. are suggested, whereas the third one, which combines excurrent costae of stem leaves and subulate acumina of the perichaetial leaves, is described as a new species, G. ambiguum Fedosov. In Russia, G. crispifolium is mostly associated with the cooler and more humid climate of hemiboreal forests, whereas G. ambiguum occurs in drier conditions in broadleaved forests. Although the niches of G. crispifolium and G. ambiguum were assessed as being rather similar, their ranges overlap weakly. Conclusions Our results suggest the presence of three species of Glyphomitrium at the northern limit of its distribution in Asia. Results of niche distribution modelling show that the two species’ distributions depend on different predictors, and thus this tool appeared helpful for integrative taxonomic purposes. By contrast, the results of the niche similarity/divergence test were inconclusive.

ABSTRACT Introduction Bryophyte diaspore banks are a critical aspect of the life strategy of some species yet remain neglected and poorly understood. This study investigated the longevity in natural habitat of the diaspore bank of Physcomitrium eurystomum Sendtn., a moss species that is threatened with extinction in Europe. Methods Undisturbed soil cores of 40 cm depth were collected from Langmere, Norfolk, UK, and were split into investigated sediment layers of 1 cm depth. Dating of sediment layers was done by an analysis of radionuclides, and diaspore germination trials of each layer were carried out in a growth chamber. DNA barcoding was used to help identify plants that germinated. Key results and conclusions Viable diaspores of Physcomitrium eurystomum frequently occurred in sediment layers that were at least 100 years old and continued to occur in much lower layers that were probably several hundred years old. The long-term survival of bryophytes underground can have important implications for conservation decisions.

ABSTRACT Introduction. Hennediella Paris is a globally distributed genus comprising 15 species, of which two are presently known from southern Africa. Field studies in the Cape winter-rainfall area yielded a specimen that could not be assigned to any of the known species of the genus and is here described as new. Methods. Specimens collected using standard bryological field techniques were rehydrated in the laboratory, dissected, and mounted in Hoyer’s solution. Observations and measurements were made using standard stereo and compound microscopy. Key results and conclusions. Hennediella austroafricana Hedd. & M.J.Cano is a new species that is currently known only from the type locality in the Cape winter-rainfall region at Drie Kuilen, where it grew in Matjiesfontein Renosterveld. It is distinct from all other members of the genus in the combination of leaves with a border of short-rectangular, thick-walled, smooth (or at least less papillose) cells, and sporophytes with a thick seta, and a peristome with a high basal membrane and relatively short, straight to slightly twisted, filiform teeth.

The purpose of this paper is to typify Sphagnum balticum (Russow) C.E.O.Jensen and provide an accompanying description. Russow’s herbarium was sold by his widow after his death and most of it ended up at the Komarov Botanical Institute of the Russian Academy of Sciences (LE). However, about half of it was returned to Estonia; most of these collections are now found in the Estonian University of Life Sciences (TAA), with the minority held in the University of Tartu (TU). Some of his collections also arrived in the Berlin Botanic Garden and Botanical Museum (B), the University of Helsinki (H) and the Swedish Museum of Natural History (S). Typification is here based on a review of material located in B, H, LE, TAA and TU, plus material from Jensen’s herbarium located in the University of Copenhagen (C). Potential material in S will not be available for study for several years, because it is in storage while the herbarium building is being renovated. There are five collections of Sphagnum made by Russow in the database for S, but none are S. balticum. Turland et al. (2018) is followed for nomenclatural guidance.
本文的目的是对Sphagnum balticum (Russow) C.E.O.Jensen进行分类，并提供相应的描述。Russow的植物标本室在他去世后被他的遗孀卖掉，其中大部分最终被俄罗斯科学院(LE)的科马罗夫植物研究所(Komarov Botanical Institute)收藏。然而，其中约有一半已归还爱沙尼亚;这些藏品现在大部分在爱沙尼亚生命科学大学(TAA)，少数在塔尔图大学(TU)。他的一些收藏也抵达柏林植物园和植物博物馆(B),赫尔辛基大学(H)和瑞典的自然历史博物馆(S)。代表在这里根据审查的材料位于B, H, LE, TAA和TU,加上材料从詹森的标本位于哥本哈根大学(C),潜在的材料不会被用于研究好几年了,因为它是在储存标本建筑正在翻新。S的数据库中有5个由Russow制造的Sphagnum，但是没有一个是S. balticum。遵循Turland等人(2018)的命名指导。

Section Papillatae Bischl. is one of the most taxonomically complicated sections in the family Marchantiaceae, due to its ambiguous interand intra-specific delimitation (Zheng and Shimamura 2022). In East Asia, for many years only two subspecies, Marchantia emarginata subsp. tosana (Steph.) Bischl. and M. papillata subsp. grossibarba (Steph.) Bischl., have been recognised in this section (Bischler 1989; Bischler-Causse 1989; Zheng and Shimamura 2020). Although this treatment has been widely adopted in almost all Asian studies, the delimitation between the two subspecies remains ambiguous due to the overlap in some morphological characters, such as the blackish median band on the dorsal surface of the thallus, appendage of the ventral median scales, number of female receptacle lobes, and angle of the basal sinus of the male receptacle. In 2022, Zheng and Shimamura first noted the presence of these ambiguities in the two subspecies of sect. Papillatae in Japan and therefore partly clarified their delimitation by reducing Marchantia tosana Steph. (≡ M. emarginata subsp. tosana) and M. tosayamensis Steph. (= M. emarginata subsp. tosana) under M. papillata subsp. grossibarba. Marchantia emarginata subsp. cuneiloba (Steph.) T.X.Zheng & M.Shimamura was subsequently proposed to replace the former M. emarginata subsp. tosana. Because of the lack of available ordinary specimens from a wide geographical range, previously synonymised taxa of M. emarginata subsp. tosana were also tentatively transferred to subsp. cuneiloba. To provide a clearer delimitation of the two subspecies of sect. Papillatae in East Asia, and to lay the foundation for a future comprehensive revision of the section, these synonyms need to be reviewed. During the taxonomic revision of the family Marchantiaceae in Asia, it has been possible to study the original material of one little known Chinese species, Marchantia fallax Herz. This species was originally described based on a specimen from Yunnan Province, China (Herzog 1930). Since then, no further information on this species was published until Bischler (1989) synonymised the species under M. emarginata subsp. tosana without providing any comments. Detailed taxonomic notes were provided in a subsequent monograph (Bischler-Causse 1989); however, this synonymy still needs to be reviewed because when this treatment was produced, the morphological concepts of accepted species in sect. Papillatae, such as M. emarginata and M. papillata, were neither well understood nor clearly defined. In this note, a detailed description of Marchantia fallax, illustrations of its important taxonomic features, and taxonomic notes are provided.
乳突节。由于其种间和种内的界限不明确，是Marchantiaceae科中分类学上最复杂的部分之一(Zheng and Shimamura 2022)。在东亚，多年来只有两个亚种，Marchantia marginata亚种。tosana(篮)。Bischl。和乳突菌亚种。grossibarba(篮)。Bischl。，已在本节中得到认可(Bischler 1989;Bischler-Causse 1989;Zheng and Shimamura 2020)。尽管这种处理方法在几乎所有的亚洲研究中都被广泛采用，但由于在一些形态学特征上的重叠，如菌体背表面的黑色中间带、腹侧中间鳞片的附属物、雌性花托裂片的数量和雄性花托基底窦的角度，两个亚种之间的界限仍然不明确。2022年，Zheng和Shimamura首次在日本的Papillatae节的两个亚种中发现了这些模糊性，因此通过还原Marchantia tosana Steph部分澄清了它们的界限。≡田螺子。tosayamensis Steph.;(= M. emarginata subsp。乳头状芽胞杆菌亚种下的芽胞菌。grossibarba。海地菜亚种cuneiloba(篮)。郑廷勋和岛村先生随后被提议取代原来的江边田先生。tosana。由于在广泛的地理范围内缺乏可用的普通标本，以前的同义分类群的emarginata亚种。Tosana也被暂时转移到subsp。cuneiloba。为了对东亚乳突科的两个亚种进行更清晰的界定，并为今后对本科的全面修订奠定基础，有必要对这些近义词进行复习。在对亚洲Marchantiaceae科植物进行分类修订的过程中，有可能对中国一个鲜为人知的种——Marchantia fallax Herz的原始材料进行研究。本种最初是根据中国云南省的一个标本描述的(Herzog 1930)。此后，关于该物种的进一步信息没有发表，直到Bischler(1989)将该物种同义归入M. emarginata亚种。托萨纳没有提供任何评论。在随后的专著(Bischler-Causse 1989)中提供了详细的分类说明;然而，这一同义词仍需要进行回顾，因为在制作这一处理时，乳突节中公认的种的形态学概念，如M. emarginata和M. papillata，既没有得到很好的理解，也没有明确的定义。本文详细介绍了黄菖蒲(Marchantia fallax)属植物，并举例说明了其重要的分类特征和分类注释。

ABSTRACT Introduction We report the results of an international bryological expedition to the Khamar-Daban mountain range in Russian southern Siberia. The novel approach of integrative floristics is introduced here as a method of surveying the flora of a region by using a combination of morphological and molecular evidence to identify and verify unexpected findings. We show that use of this approach can deliver a high level of credibility in cases in which direct molecular comparison is possible or the relevant data can be easily obtained from reliable studies informing recent treatments. Integrative floristics can also be used to identify potential taxonomic problems requiring further study. Methods Conventional identification methods based on plant anatomy and morphology were supplemented with molecular barcoding (nuclear ITS, plastid trnL–trnF, rps4 and atpB–rbcL regions) of specimens that either did not fit existing morphological concepts perfectly or for which records were unexpected based on previously established phytogeographical patterns. Key results and conclusions In total, we recorded ca 380 species of mosses and ca 150 species of liverworts from five localities on the northern slopes of the Khamar-Daban range. Such floristic richness indicates a hotspot of bryophyte diversity with a remarkably high proportion of suboceanic species, such as Brachydontium trichodes (F.Weber) Milde, Herzogiella striatella (Brid.) Z.Iwats. and Racomitrium macounii subsp. alpinum (E.Lawton) Frisvoll. Nearly 20% of specimens were identified or checked using DNA barcoding. This approach showed the presence of previously unrecorded species in a number of genera, including Didymodon, Neckera and Pseudohygrohypnum.

This approach showed the presence of previously unrecorded species in a number of genera, including Didymodon, Neckera and Pseudohygrohypnum.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":"44 1","pages":"107 - 133"},"PeriodicalIF":1.9,"publicationDate":"2022-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45538705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT Introduction Recent bryological research in Portugal has revealed the occurrence of a little-known segregate of the Riccia sorocarpa group, representing the first record for mainland Portugal and the Azores of Riccia sorocarpa Bisch. subsp. erythrophora R.M.Schust. ex Konstant. & L.Söderstr. New data are presented on the taxonomy and phytogeography of this globally rare taxon. Methods A revision of approximately 200 samples of Riccia sorocarpa s.l. from selected Portuguese herbaria, together with some recent field collections, was carried out, based on the results of light and scanning electron microscopy. Key results and conclusions Our findings confirm that Riccia sorocarpa subsp. erythrophora is a distinct subspecies, and show that morphological differences of the thallus, primarily the violet-red purple bases of the ventral scales, are the most important characters for its delimitation. Scanning electron micrographs of spores of this taxon are presented for the first time. Phytogeographically, our data significantly extend the known distribution of the subspecies.
