During our studies of Indian hornworts, a distinctly variable population was found at Binsar, Uttarakhand, and sharing the same habitat as Phaeoceros himalayensis (Kashyap) Prosk. ex Bapna & G.G.Vyas and Phaeoceros laevis (L.) Prosk.Methods A critical study of the specimens housed at CSIR–NBRI, Lucknow (LWG) was conducted. An SEM study of spores was also carried out to examine their ultramorphological characters.Key results The plants were found to be remarkably characterised by a narrow thallus with prolific stalked tubers arising from the mid-ventral surface; female plants with short involucres; single rounded to irregular chloroplast per cell, without a pyrenoid; and spore distal face with a large, central, single, pitted central hump, and the proximal face with a distinct single dimple on each tetrahedral area between triradiate rays. A detailed morphotaxonomic account is presented, along with detailed SEM observations of spores of the Indian plants.Conclusion Our critical comparative study has revealed that the plants of the newly recorded population belong to the genus Phymatoceros and are distinct from hitherto known species. They are described here as a new species, Phymatoceros binsarensis A.K.Asthana, D.Shukla & Reesa Gupta, and are the first record of Phymatoceros in India. As such, they represent a remarkable and interesting disjunct occurrence of the genus in Asia, separate from its distribution in four other continents (Africa, Europe, and North and South America).

Having 29 species in California, Grimmia Hedw. is the third richest moss genus in the state, but recent fieldwork suggests that this number is an underestimate. The identity of some specimens endemic to the Klamath Mountains of California and previously identified as G. brevirostris R.S.Williams remains unclear, and they potentially represent a new species. Two further specimens of Grimmia from Siskiyou County, California, do not correspond to any species described so far. Here we present morphological and phylogenetic arguments for recognising these plants as two new moss species in the genus Grimmia subg. Orthogrimmia Schimp. Methods Morphological characters across potential new species were reviewed and compared with those of related species. Phylogenetic analyses based on the plastid trnS–trnF and nuclear ITS regions were conducted. Key results and conclusions The molecular and morphological analyses revealed two new species of Grimmia for California, which are described and illustrated: G. shevockii J.Muñoz, I.Solano & D.Quandt and G. insolita J.Muñoz, I.Solano & D.Quandt. The former is resolved in a monophyletic clade with high support, whereas the latter has incongruent positions in the plastid and nuclear phylogenies, thus it is hypothesised that it could have a hybrid origin. Both of the two new species and G. hamulosa undoubtly pertain to Grimmia. The richness of the bryophyte flora of California provides a clear warrant for future research.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42966884","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}

We present here our preliminary results based on recent fieldwork and herbarium studies. Methods We recorded bryophyte occurrences in grid cells (quadrants) of approximately 5.5 × 6 km. Frequency was determined based on the number of quadrants, and geographical distribution evaluated in terms of the 19 administrative units (counties) of the country. To investigate correlations between species richness and relevant environmental drivers, statistical analyses were carried out. Key results A total of 698 bryophyte taxa (2 hornworts, 151 liverworts and 545 mosses) have been found in the territory of Hungary. For each of the 637 taxa that have been observed since 1973, one of five frequency classes (very common, common, sporadic to frequent, rare, and very rare) has been assigned based on the relevant number of field records or herbarium specimens. Additionally, tabular distributional information (occurrence in each of the 19 counties) is presented for each taxon. In the statistical evaluation of the geographical distribution data, the elevational range and the size of the surveyed area were positively correlated with bryophyte richness, whereas arable land cover was negatively correlated. Conclusions Although the survey was not uniform or complete across the different counties, the results support some robust bryogeographical theories. We hope to have the opportunity in the near future to compile a new Hungarian bryophyte Red List, partly based on these national frequency data.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41798020","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}

Methods Surveys were undertaken at all locations from where the species has been known and counts made of individual-equivalents (occupied 1 m grid cells). Light loggers were used to measure the light regime across a full annual cycle at a control site and at colonies of the liverwort within deciduous woodland and heathland habitat, from which percentage shade was calculated. Key results and conclusions The species was refound at all eight locations at which it has been known previously. A total of 157 individual-equivalents were found and it is estimated that the real total is 189–300 individual-equivalents, with the largest populations at Bonython (64 individual-equivalents counted; 41%) and Poltesco (44 individual-equivalents counted; 28%). High illuminance (> 10,000 lux) was recorded commonly at the control site (29.5% of measurements; n = 52,560), rarely in heathland (2.6–6.6%) and never in deciduous woodland. Compared with heathland, shade in deciduous woodland is higher (annual mean = 78.4–91.1% vs 98.4–98.5%) and more consistent throughout the year. The status of the species across the Lizard Peninsula seems to be favourable, but the small size of the population and its localised occurrence mean that it will remain vulnerable.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47903843","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}

Methods All sites at which Sphagnum balticum has been recorded recently in Britain were visited in 2020, and a search made for it and other species with which it could be confused, together with possible hybrids. Samples were collected when suitable material was found. DNA was extracted from 31 shoots, each representing one field sample. Fifteen microsatellites that have been developed for Sphagnum species were amplified and genotyped. The genetic structure of the data was investigated using principal coordinate analysis and cluster analysis. Results The results of the genetic analysis support the recognition of four taxa, which corresponded to four morphologically identified taxa: Sphagnum angustifolium, S. balticum, S. cuspidatum and S. fallax. There was no evidence of hybrids. Over-recording of S. balticum has occurred in Britain due to confusion with some forms of S. cuspidatum and S. fallax, which can exhibit some morphological characters usually used to identify S. balticum. An illustrated identification key is provided to help solve this problem. Conclusions Sphagnum balticum is a very rare species in Britain that has undergone a decline due to habitat destruction and alteration. It is presently known to survive at only three sites, of which two are within protected areas.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48758752","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}

The aim of this study was to investigate the value of such records as evidence of change in the condition of protected areas. Methods The study area comprised Epping Forest, UK, where basic bryophyte recording has been undertaken ad hoc since ca 1800 and was again carried out in January 2022. A total of 224 species were included within the analysis, each categorised as either having been found during the surveys in January 2022 or only found during previous recording. Ellenberg indicator values for each species were derived from published literature. To investigate if any of the Ellenberg indicators were significant predictors of whether or not a species was found during the January 2022 surveys, a binomial generalised linear model was constructed (model 1). A second similar model was produced that excluded epiphytes (model 2). Results Regarding the likelihood of a species having been found during January 2022, model 1 indicated that there were highly significant negative relationships with moisture and acidity, and a highly significant positive relationship with nitrogen. Model 2 provided similar results except that moisture was insignificant. Conclusions Basic bryophyte records indicated that the condition of Epping Forest has undergone significant change, to become a site that is less acidic and more nutrient rich. This is consistent with a known decline in sulphur dioxide pollution and an increase in nitrification.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44555774","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}

It was based on Ulota bellii, a species described by Nikolajs Malta for which only two previous collections were known. Despite this sample size limitation, Malta simultaneously published two varieties, each based on one of the two specimens: the type variety and U. bellii var. longicolla. Methods Specimens from 80 localities between 0 and 1430 m a.s.l. from both the North and South Islands of New Zealand were studied. Type material of both varieties of Ulota bellii was included in the study, and the ecological affinities of Rehubryum bellii were analysed. Key results and conclusions Morphometric analysis supports the conclusion that our recent collections correspond to the original concept of Ulota bellii, now combined as Rehubryum bellii. Additionally, var. longicolla is synonymised with the type variety based on a lack of morphological differences. Rehubryum bellii is described in detail and illustrated, and its distribution and ecological affinities are discussed. Rehubryum bellii presents a set of morphological diagnostic characters: leaves with a submarginal band of elongate cells, papillose-denticulate margins in the base–lamina transition, and an endostome with 16 segments. Similarities and differences between Rehubryum and Atlantichella, the sister genus from the northern hemisphere, as well as the distinction from Australasian species of Orthotrichaceae, are discussed. The genus is now known from 12 localities in montane areas of the South Island of New Zealand and two isolated mountains on the North Island.","PeriodicalId":54869,"journal":{"name":"Journal of Bryology","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2023-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41887510","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}
