Sequencing showed the species and, because it is very similar to the type species, the genus, which was lastly cited as incertae sedis, to belong to the Ramalinaceae. A new species from the Amazon was also shown to belong to the Ramalinaceae and the new genus Appressodiscus is erected to accommodate this species, as well as a species that was recently described in the genus Ramboldia.

{"title":"A chemistry overview of the beautiful miniature forest known as mosses","authors":"W. R. Sala-Carvalho, D. F. Peralta, C. Furlan","doi":"10.1639/0007-2745-126.3.342","DOIUrl":"https://doi.org/10.1639/0007-2745-126.3.342","url":null,"abstract":"Abstract. The bryophytes are the second largest group of land plants and are represented by three lineages: Marchantyophyta (liverworts), Anthocerotophyta (hornworts), and Bryophyta (mosses). They occupy a wide variety of habitats, from deserts to Antarctica, and exercise great ecological importance. These facts and their wide use in traditional medicine raise the question of what is known about moss chemistry. This paper gathered studies from the last 52 years about the compounds identified in mosses, aiming to address the following questions: Are mosses chemically under-studied? How many families, genera, and species of mosses have been chemically studied? Which continent and countries have been responsible for the majority of these studies? A literature search was performed in major scientific databases, using a combination of keywords. A total of 199 papers were compiled, of which 45% were published during the last decade. Only a small percentage of moss species has been studied, mostly from Europe and Asia. Dicranales and Hypnales are the most studied orders. In general, fatty acids and flavonoids are the most commonly reported classes of compounds. Biflavonoids and triflavonoids are detected mainly in derived clades of mosses, while coumarins are most reported for basal groups. Akthough only a small percentage of moss species has been chemically studied, most of these studies were published in the last decade—there has been a 135% increase in the number of reported compounds in the last 13 years. The emergence of new equipment, which can produce high-resolution spectra with small amounts of sample, combined with bioinformatics tools, has undoubtedly contributed to the increase of chemical investigation of mosses. Also, advances in the identification and phylogenetics of moss groups are contributing to a better understanding of them generally, which should lead also to increased study of moss chemistry.","PeriodicalId":55319,"journal":{"name":"Bryologist","volume":"1 1","pages":""},"PeriodicalIF":0.9,"publicationDate":"2023-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44141253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Though Klips is the only author of the book, OMLA members contributed some illustrations, feedback, and supplying poetry folded between the chapters. The book is intended primarily for aspirant cryptogam naturalists and aims to inspire curiosity in readers. By providing a ‘‘starter set’’ of cryptogams, this book pushes them to ‘‘dig deeper using microscopes and more technical manuals.’’ The spectacular macro-photography truly captures the complexity of the various organisms included, and the ecological roles they serve. Klips uses these photos to explain technical terms and concepts, highlighting key differences in leaf morphology, habitat utilization, reproductive structures such as sporangia and gametangia, and other details pertinent to cryptogram identification. The first chapter of the book provides an overview of mosses, liverworts, hornworts, and lichens. In this section, Klips emphasizes the ecology of bryophytes and lichens, describing how to find them, where they grow and how they survive, and their importance in the ecology of other organisms. Book chapters dedicated to the mosses are organized by morphology and include treatments for 106 of the more than 400 species of mosses in Ohio (Andreas 2011). The moss species accounts are divided into ten chapters – four chapters dedicated to acrocarps (the ‘‘cushion mosses’’), three chapters dedicated to pleurocarps (the ‘‘carpet mosses’’) and three chapters dedicated to the ‘‘weird ones’’ that are so different from the rest that they do not fall into either category. The sections are further broken down by leaf features. The acrocarps are separated by leaf shape (hairlike, lance-shaped, tongue-shaped, broad), the pleurocarps are separated by costa and leaf shape (sickle-shape, costate, ecostate), and the others are split into three groups (Flat Fissidens and Friends, Haircap Mosses, Sphagnum Mosses). Ultimately, Klips spends one chapter divided into ten sections discussing how to identify mosses. Thirty-one taxonomic treatments of the approximate 100 liverwort species that have been recorded in Ohio are included in this book (OMLA). Three species of hornworts are addressed in this section, though they are not included in the taxonomic treatments. The liverworts are divided into fourteen different groups representing ‘‘growth form categories helpful in identification,’’ such as ‘‘leafy liverworts with toothed leaves and succubous insertion,’’ which is consistent with grouping schemas in scientific literature. According to the OMLA website, there are more than 200 species of lichen in Ohio, 101 of which are included in the book (OMLA).

In this study, we revised the lichen collection at the Herbario Amazonico Colombiano (coah) in Bogotá, Colombia. The collection has a total of nearly 2,400 specimens, with some duplicates in the Herbario Nacional (col) and in the herbarium of the Botanic Garden in Berlin (b). The revision of 1,861 specimens revealed 574 species in 142 genera and 44 families, among which there are 28 species new to science and seven new combinations. Previously, 324 species had been reported from the Colombian Amazon, and our revision resulted in a new total of 666 species, more than doubling the previous number. All 666 species are enumerated here in the first comprehensive checklist of lichens from the Colombian Amazon.

Gentle, modest Robert Root Ireland was one of Canada’s foremost bryologists and a key role model in many natural history careers. His legendary hard work, accuracy, and attention to detail set a highly motivating standard. His generosity and kindness encouraged others to be the same. His actions spoke persuasively, while he himself said as little as possible to call attention to his excellence and considerable influence. Bob was born, raised and educated in the state of Kansas, U.S.A. By the time he had earned his B.A. from the University of Kansas in 1956, he had also served a year in the navy, and had found his wife and lifelong partner, Ellen. He graduated with an M.A. (Botany) in 1957, having completed his thesis on ‘‘Biosystematics of Erythronium albidum and E. mesochoreum.’’ That same year, his bryological career began when he obtained the position of Herbarium Aid in Cryptogams at the United States National Herbarium (Smithsonian Institution). A year later, he advanced to Assistant Curator of Bryophytes. Learning very effectively on the job, Bob published his first bryology papers during those early years at the Smithsonian. He also attended a bryophyte course at the University of Michigan Biological Station, where he began an enduring friendship with mentor A. J. Sharp, who Bob affectionately dubbed ‘‘Uncle Jack.’’ At Sharp’s urging, in 1962, Bob became assistant to University of Washington (Seattle) professor, Elva Lawton, who was newly funded to create the Moss Flora of the Pacific Northwest (Lawton 1971). This work launched his interest in chromosome studies, which he undertook in support of the flora project. Soon, he also began to work on his Ph.D. studying the moss genus Plagiothecium in North America. After completing his doctorate in 1966, Bob was hired as Curator of Bryophytes at the Canadian National Museum of Natural Sciences (now the Canadian Museum of Nature, CMN) in Ottawa, Canada, replacing Howard Crum, who had held the post since 1954 before moving to the University of Michigan. In this role, Bob assumed responsibility for curating a relatively small but significant national bryophyte collection (CANM) that was founded in the 1800s by ‘Dominion Botanist’ John Macoun. In fact, when Bob arrived, the herbarium was still crowded into the same historic stone building where Macoun himself had worked. However, as the heavy Victorian edifice sank a few centimeters each year into the soft clay on which it had been built, the Botany collection soon moved to an ill-suited (if roomier) ‘‘temporary’’ home in an Ottawa office building . . . where it remained for more than thirty years. Despite the challenges, the collection grew from fewer than 100,000 to more than 250,000 specimens during Bob’s curatorship, through active exchanges with a multitude of institutions around the world, a busy donation-in-return-for-identification program, field work, adoption of orphan col","PeriodicalId":55319,"journal":{"name":"Bryologist","volume":"126 1","pages":"217 - 220"},"PeriodicalIF":0.9,"publicationDate":"2023-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47145836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
