Haughian S.R., Medeiros H.R., Tenwolde K. & Harper K.A. (2025): Effects of gastropod exclusion and phosphate fertilization on Lobaria pulmonaria growth, Bryologist, 128(4): 746–754

Epiphytic lichens face increasing threats in per-humid temperate and boreal forests where many species are declining. A significant threat to some lichens, particularly those with a cyanobacterial symbiont, is overgrazing by invasive gastropods. This study tests two possible applied conservation measures that could reduce overgrazing from invasive gastropods or promote faster lichen recovery: (1) fertilization with potassium phosphate solution, and (2) slug exclusion via wrapping copper foil around … Read more...

Brodo I.M. & McMullin R.T. (2025): A revision of Pannaria rubiginosa s.l. (Pannariaceae) in eastern North America, Bryologist, 128(4): 727–745

Although the western populations of Pannaria rubiginosa s.l. have recently been revised resulting in the description of a new species, P. oregonensis, no detailed review of the eastern populations has been made since Jørgensen's monograph of North American Pannaria species in 2000. The present study, based on morphological, chemical and molecular data, has uncovered a new species in the east, P. subrubiginosa, characterized by its production of pannarin at least in the medulla, and has revised the … Read more...

Schmidt S.K., Cramm M.A., Solon A.J., Bradley J.A., Bueno de Mesquita C.P., Cimpoiasu M.O., Rubin R.R., Quispe Pilco R., Kuras O. & Irons T.P. (2025): Biological soil crust microcolonies reveal how microbial communities assemble following retreat of a High Arctic glacier, FEMS Microbes, 6: xtaf007 [10 p.]

Little is known about biological soil crust (BSC) formation during the early stages of primary succession following glacial retreat. Here, we report on focused sampling of twelve discrete BSC colonies near the snout of a retreating glacier in the High Arctic and show that BSC colonies had significantly higher 16S and 18S rRNA gene diversity than the simpler communities of bare sediments sampled next to each colony. Surprisingly, the colonies also had a higher degree of community dispersion than the … Read more...

Jiang S.-H., Xu Y.-K., Zhao X. & Jia Z.-F. (2025): A morphological and molecular analysis reveals a new species in the genus Diorygma (Graphidaceae, Ostropales) from Zhejiang Province, China, Phytotaxa, 720(1): 57–66

A new species of the lichenized fungi genus Diorygma is described from China: Diorygma jingningense Shu H. Jiang & Z.F. Jia, collected from Zhejiang Province. It is characterized by a saxicolous and pseudocorticate thallus, erumpent lirellae with complete thalline margin, entire labia, uncarbonized excipulum, hyaline hymenium, small, submuriform, 3 × 0–1-septate ascospores and the presence of norstictic and connorstictic acids. The placement of this new species was confirmed by a molecular phylogenetic … Read more...

Kono M., Ohmura Y. & Terai Y. (2025): The first whole genome sequencing of historical lichen specimens enables genome-wide analysis of fungal and algal symbionts, Ecology and Evolution, 15: e72216 [9 p.]

With the advent of high-throughput sequencing techniques, natural history museums and herbaria have become new frontiers for genetic research. Genomic information from historical specimens has provided evidence to solve significant questions in broad research areas. However, access to such valuable genetic resources remains limited in lichens due to experimental challenges in extracting and amplifying highly degraded DNA in historical specimens. So far, only a handful of studies have reported successful … Read more...

Haughland D.L., Maloles J.R., Selva S.B., Thauvette D., McMullin R.T., Porter E., Bull R.D., Williston P. & Lane C. (2025): Calicioids of Alberta, Canada, with descriptions of three new genera and 13 new Sphinctrinaceae species to science, Bryologist, 128(4): 607–726

At 661,848 km2, the province of Alberta, Canada is a biogeographically variable political region, located at the confluence of eight ecoregions. The provincial lichen flora was surveyed in several foundational North American studies, and recent increased survey effort from researchers, environmental impact assessments, group forays, and a province-wide biodiversity monitoring program have built on that foundation. Subsequent collections of calicioid lichens and allied fungi necessitated a large floristic … Read more...

Andrzejowska A., Bernatová M., Hájek J., Sekerák Jr. J.. & Harańczyk H. (2025): Low temperature inhibition of photosystems I, and II in Antarctic lichens of different morphotypes, Czech Polar Reports, 14(2)[2024]: 336–348

Chlorophyll fluorescence techniques represent an effective tool for photosynthetic performance of extremophilic poikilohydric autotrophs from cold Earth regions. Many parameteres of these techniques can detect the response of photosystem II (PS II) to a great variety of stressors. Chlorophyll fluorescence parametrs related to PS II funcioning are used quite often. For Antarctic lichens, that evolved several physiological mechanisms to cope with close to 0°C or even at sub-zero temperatures. The … Read more...

Cao S., Yang C., Tian H., Shen Y., Peng F. & Zhou Q. (2025): Deuterostichococcus alpinus sp. nov. (Chlorophyta; Trebouxiophyceae) from Antarctica, Czech Polar Reports, 15(1): 146–166

Lichens are the most dominant components in flora of Antarctica. A lichen epiphyte green alga FACHB-2327, isolated from Antarctic lichen Stereocaulon alpinum, was identified as a new species belonging to the genus Deuterostichococcus. The specimen of lichen Stereocaulon alpinum was collected from King George Island, Antarctica. A comprehensive analysis, including morphology, ultrastructure, habitat, phylogeny and secondary structure of SSU rDNA V9 region, was carried out. The green alga FACHB-2327 … Read more...

Rubio C., Ramírez J., Rojas J.L., Valencia-Islas N.A., Campos C. & Quiñones N. (2025): Antioxidant and Photoprotective Capacity of Secondary Metabolites Isolated from Pseudocyphellaria berberina, Molecules, 30(18): 3833 [14 p.]

Exposure to sunlight, whose main component is UV radiation (UVR), leads to various skin damage such as sunburns, premature aging, or more severe issues such as increased symptoms of autoimmune disease and skin cancer. Therefore, there is a growing interest in developing improved photoprotective agents that can protect skin from sunlight incidence and antioxidants that counteract the oxidative stress caused by it. Lichens are a source of such agents since they adapt to extreme environments including … Read more...
