Vagle G.L., Lendemer J.C., Manzitto-Tripp E.A. & McCain C.M. (2024): Patterns and predictors of lichen rarity in a biodiversity hotspot - Biodiversity and Conservation, (2024): 1-22

Understanding the spatial distributions of rarity and diversity is crucial for both targeted conservation efforts and elucidating the mechanisms that underpin species richness patterns. Existing studies suggest local communities with greater species richness also hold higher numbers of low abundance species. Rarity hotspots at the global scale tend to be spatially divergent from species richness hotspots and differ among many taxonomic groups, but much less work has been done to understand rarity … Read more...

Westberg M., Wedin M. & Svensson M. (2024): Myriospora molybdina comb. nov. and the identity of Acarospora hysgina - Nordic Journal of Botany, 2024: e04269

The nomenclature and taxonomy of Acarospora molybdina is revised using morphological and molecular data. The new combination Myriospora molybdina is proposed and Acarospora hysgina is recognized as a distinct species while A. brunneola is reduced to synonymy with A. hysgina. In its new circumscription M. molybdina is an arctic species, in Scandinavia only occurring in northernmost Norway. Further localities are reported from Greenland, Russia, Svalbard and the USA (Alaska). Acarospora hysgina is … Read more...

Jung P., Baumann K., Emrich D., Schermer M., Eckhardt K.-U., Jandl G., Leinweber P., Harion F., Wruck A., Grube M., Büdel B. & Lakatos M. (2024): The dark side of orange: Multiorganismic continuum dynamics within a lichen of the Atacama Desert - Mycologia, 116(1): 44–58

Over the decades our understanding of lichens has shifted to the fact that they are multiorganismic, symbiotic microecosystems, with their complex interactions coming to the fore due to recent advances in microbiomics. Here, we present a mutualistic-parasitic continuum dynamics scenario between an orange lichen and a lichenicolous fungus from the Atacama Desert leading to the decay of the lichen’s photobiont and leaving behind a black lichen thallus. Based on isolation, sequencing, and ecophysiological … Read more...

Pląskowska E., Patejuk K., Lorenc M.W. & Grzeszczuk J. (2024): Lichens and Fungi on Sandstone Tombs at the Historical Jewish Cemetery in Wrocław (Poland) - Studies in Conservation, 69(1): 58–66

Microflora inhabiting rock surfaces, including bacteria, fungi, algae, and lichens, form a specific kind of an ecosystem. Unique and not well known forms of this environment are old cemetery tombs. To better understand such environments, lichenological and mycological studies were conducted in the old Jewish cemetery in Wrocław, Poland. The research covered 13 tombstones made of several varieties of sandstone. This research shows that some gravestones made of sandstone from Wartowice were strongly … Read more...

Moya P., Chiva S., Pazos T., Barreno E., Carrasco P., Muggia L. & Garrido-Benavent I. (2024): Myco–phycobiont interactions within the “Ramalina farinacea group”: A geographical survey over Europe and Macaronesia - Journal of Fungi, 10(3): 206 [17 p.]

Ramalina farinacea is a widely distributed epiphytic lichen from the Macaronesian archipelagos to Mediterranean and Boreal Europe. Previous studies have indicated a specific association between R. farinacea and Trebouxia microalgae species. Here, we examined the symbiotic interactions in this lichen and its closest allies (the so-called “R. farinacea group”) across ten biogeographic subregions, spanning diverse macroclimates, analyzing the climatic niche of the primary phycobionts, and discussing … Read more...

Maccarelli L., Schaeffer T.T., Smith G.D. & Chen V.J. (2024): Components of mid-nineteenth- and mid-twentieth-century cudbears - Heritage, 7(3): 1357–1371

Analysis of purple dyestuff from a tin labeled “1 oz. Cudbear, No. 1 N. F. Powdered”, marketed by the American business S. B. Penick & Company, “Manufacturers of fine drugs and chemicals”, confirmed that the material was indeed a lichen dyestuff. It contains the same major orcein components identified in several other lichen dyes and dyed samples dating from the mid-19th century to today. These dyestuffs were analyzed using several analytical techniques. Fluorescence and fiber optic reflectance … Read more...

Kubiak D. (2024): “Sosny Taborskie” nature reserve as a refuge for rare and threatened forest lichens - Folia Forestalia Polonica, Series A – Forestry, 66(1): 8–21

The article presents the results of a lichenological inventory carried out in the “Tabórz Pine” nature reserve, which protects a unique old-growth forest dominated by Scots pine and European beech. The aim of the research was to document the taxonomic and ecological diversity of the lichen biota in the reserve and, on this basis, determine the role and importance of this site as a refuge for stenoecious forest lichens. In an area of 95.32 ha, 118 species of lichens were found, including … Read more...

Wierzcholska S., Łubek A., Dyderski M.K., Horodecki P., Rawlik M. & Jagodziński A.M. (2024): Light availability and phorophyte identity drive epiphyte species richness and composition in mountain temperate forests - Ecological Informatics, 80: 102475 [10 p.]

Bryophytes and lichens are the most species-rich groups of epiphytes in temperate forests. They colonise different tree species that create a wide variety of microhabitats, and conditions in these microhabitats are modulated by different factors. We assessed drivers that create and maintain epiphyte species richness and diversity of bryophytes and lichens along tree species composition gradients. We hypothesised that tree species composition influences the diversity of lichens and bryophytes. The … Read more...

Bakacsy L. & Szepesi Á. (2024): A case study on the early stage of Pinus nigra invasion and its impact on species composition and pattern in Pannonic sand grassland - Scientific Reports, 14: 5125 [10 p.]

Alien woody species are successful invaders, frequently used for aforestation in regions like semi-arid lands. Shrubs and trees create important microhabitats in arid areas. Understorey vegetation in these habitats has unique species composition and coexistence. However, the impact of solitary woody species on understorey vegetation is less understood. This study evaluated the effect of native (Juniperus communis) and invasive solitary conifers (Pinus nigra) on surrounding vegetation, where … Read more...

Cho M., Lee S.J., Choi E., Kim J., Choi S., Lee J.H. & Park H. (2024): An Antarctic lichen isolate (Cladonia borealis) genome reveals potential adaptation to extreme environments - Scientific Reports, 14: 1342 [11 p.]

Cladonia borealis is a lichen that inhabits Antarctica’s harsh environment. We sequenced the whole genome of a C. borealis culture isolated from a specimen collected in Antarctica using long-read sequencing technology to identify specific genetic elements related to its potential environmental adaptation. The final genome assembly produced 48 scafolds, the longest being 2.2 Mbp, a 1.6 Mbp N50 contig length, and a 36 Mbp total length. A total of 10,749 protein-coding genes were annotated, … Read more...
