Preussia (including species until recently classified within Sporormiella) include dung-, soil-, and plant-inhabiting strains with considerable diversity worldwide. We used morphological evidence and phylogenetic analyses (nuclear ribosomal internal transcribed spacers and 5.8s gene, the adjacent D1-D2 region of the nuclear ribosomal large subunit, and for a subset of strains, the translation elongation factor 1-alpha, EF1-a) to identify distinctive members of the Preussia intermedia clade occurring as endophytes in E. trifurca. These include P. arizonica sp. nov., which also occurs as an endophyte in other plants of the region, and P. elegans sp. nov., which has been found only in E. trifurca to date. We also propose Preussia mariae sp. nov., allied phylogenetically with Preussia lignicola but distinguishable on the basis of morphology and EF1-a data. Our analyses illustrate the potential for several currently recognized species of Preussia to represent species complexes that should be resolved by analyses of additional loci and by further sampling of endophytes, which may provide an ecological connection among strains occurring within living plant tissues and as coprophilous or soil-inhabiting fungi. More broadly, our work expands the known geographic scope, host use, and diversity of Preussia, especially in arid lands. In conjunction with previous work, our study also provides the basis for hypotheses regarding secondary metabolites of the newly described species.","PeriodicalId":52151,"journal":{"name":"Plant and Fungal Systematics","volume":"54 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69872657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Molecular analyses confirmed the conspecificity of Syntrichia sarconeurum with S. lithophila and S. pygmaea. This taxonomic conclusion implies that the correct name for the species in the genus Syntrichia is S. lithophila and S. sarconeurum is a new synonym of this name. It is because S. sarconeurum takes priority from 2007, whereas S. lithophila is based on Tortula lithophila which was validly published in 1906 and it is the next earliest legitimate name at the rank of species to be used. Syntrichia sarconeurum, as traditionally conceived, proved to be a heterogeneous taxon actually consisting of two distinct species, namely S. lithophila and S. frigorideserticola nom. nov., which is a new name for Sarconeurum antarcticum whose epithet is not available in Syntrichia. Australian and New Zealand plants of Syntrichia with propaguloid leaf apices are definitely distinct from South American and Antarctic S. lithophila and S. frigorideserticola and the correct name for them is S. abruptinervis comb. nov., based on Tortula abruptinervis.","PeriodicalId":52151,"journal":{"name":"Plant and Fungal Systematics","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69872876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Endophytes occur within living plant tissues and are known from diverse aquatic, marine, and terrestrial plants, where they often mitigate plant responses to stress. As part of a study evaluating endophyte communities associated with aquatic plants in lentic waters of Arizona, USA, we isolated a distinctive clade of endophytes from healthy, living roots of seasonally inundated P. amphibia, which we describe here on the basis of morphology and evidence from four loci as new species Clohesyomyces symbioticus (Lindgomycetaceae, Pleosporales, Dothideomycetes, Ascomycota). Clohesyomyces has long been considered a monotypic genus comprising the saprobic species C. aquaticus, presently known from submerged wood in freshwater systems in Asia and Australia.

The present review looks at the results of the research on the taxonomy of plants carried out by the team led by A. Boratyński. The team characterized the taxonomic and geographical differentiation of some species of the genera Abies, Juniperus, Pinus, Cupressus, Cedrus, as well as several others. Many of these studies were carried out in the Mediterranean area due to its importance for biodiversity. The results allowed unravelling taxonomic ambiguities, emphasizing the importance of geographic barriers in shaping variability, e.g., the Strait of Gibraltar or the Aegean Sea, and highlighting the role of mountain ranges as refuges, e.g., the Taurus and Anti-Taurus Mountains. All of the results obtained with biometrics were confirmed by genetic methods by different authors. Detailed research allowed the publication of a new name, Juniperus thurifera subsp. africana (Maire) Romo & Boratyński, stat. nov., and restoration of species status for the dubious taxon Juniperus canariensis. The review shows that relying on the research of a large number of correctly sampled populations and correctly selected differentiated characteristics of plants allows the generation of reliable results.","PeriodicalId":52151,"journal":{"name":"Plant and Fungal Systematics","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49337756","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

He graduated from the Faculty of Forestry at the Poznań University of Life Sciences (previously, the August Cieszkowski Agricultural University of Poznań). Presently, he is a senior professor, very active as a researcher and educator and with great organizational skills. He is also an author and co-author of many scientific articles, monographs, atlases and chapters in the books that are of significant importance for the world’s scientific literature. Trees and shrubs in the scientific life of Professor Boratynski are the focus of his research. The professor, apart from scientific articles, is the author of monographic studies of various tree species in the encyclopedia ‘Enzyclopädie der Holzgewächse’. Professor Boratyński is a friend of many botanists, especially young people. He always has time for conversations with them about science and life in general and is very interested in their problems, both scientific and connected with everyday life. He inspires young people to create different alternative hypotheses and search for and use various tools and technologies to solve research problems. Professor Boratyński has been continually developing his research techniques. He is one of the first Polish botanists to apply genetic analyses to solve phytogeographical problems and formed a team of young people, who presently develop high level research in the area of phylogeography, based on molecular techniques. Professor Boratyński is also a passionate traveller, who uses travels for nature observation and collecting material for studies in plant systematics, chorology and ecology. Among Professor’s favourite research regions are the Mediterranean Basin and Sudeten Mountains (Figs 1–2). The Mediterranean Sea (mediterraneus from Latin – inland or in the middle of the land) significantly affects the climate and vegetation of surrounding areas. It is vegetation of this region, particularly the dendroflora of Greece, Spain and some Mediterranean islands, which has been in the center of Professor’s scientific interests. In this place, it is worth recalling the work on dendroflora of Greece or the monograph of Empetraceae on the Iberian Peninsula, written in cooperation with his Spanish colleagues from the Botanical Institute of Barcelona. The Sudetes are the second special place for Professor Boratyński. The dendroflora of Karkonosze Mountains, the highest range of the Sudetes, was the study object of his habilitation thesis. No doubt, the biology and ecology of common yew (Taxus baccata) and many other trees were investigated in depth thanks to the Professor’s research. The current issue of the journal Plant and Fungus Systematics is dedicated to Professor Adam Boratyński.
