Gupta A., Singh A.P., Singh P.R. & Sinha R.P. (2026): Photoprotective role of the lichen pigment parietin against UVR-induced damage in the cyanobacterium Synechocystis sp. PCC 6803, Dyes and Pigments, 246(1): 113405 [11 p.]

Parietin is an orange anthraquinone secondary metabolite found in the top layer of the upper cortex of some lichens such as Xanthoria elegans. In the present investigation, parietin was characterized using high-performance liquid chromatography (HPLC) alongwith photodiode-array detection and HRMS (retention time: 6.7 min; UV λmax: 265.3, 286.7 and 434 nm; [M+H]+m/z: 284). Cyanobacterial cells are severely damaged by ultraviolet radiation (UVR), which mainly affects their lipids, proteins, DNA, … Read more...

Guêné-Nanchen M., Rochefort L., Pouliot R., Boucher C. & Pouli M. (2025): Environmental drivers of bryophyte distribution and habitat preference in Sphagnum peatlands of Eastern Canada, Botany, 103: 1–22

The concept of habitat niche describes species distribution, aids in analyzing community structure, function, and diversity in changing environments, and guides peatland restoration and conservation efforts. Information on peatland sedges and bryophytes is available for Western Canada, but the habitat niche of peatland bryophytes is minimally described in Eastern Canada. Using data from 1403 quadrats in 168 Sphagnum-dominated peatlands across three climatic regions, the habitat preferences of dominant … Read more...

Meier M.F., Rocha A.M., González Réyes A.X. & Solans M. (2025): Hongos liquenizados del género Pseudocyphellaria (Ascomycota liquenizados: Lobariaceae) como microhábitats de tardígrados en bosques templado-fríos del noroeste patagónico (Argentina) [Lichenized fungí of the genus Pseudocyphellaria (lichenized Ascomycota: Lobariaceae) as microhabitats for tardigrades in temperate-cold forests of Northwestern Patagonia (Argentina)], Boletín de la Sociedad Argentina de Botánica, 60(3): 193–204

[in Spanish with English summary: ] Background and aims: Lichenized fungi are key components of Andean-Patagonian forests due to their role in nutrient cycling and their high epiphytic diversity. Among them, Pseudocyphellaria-one of the largest genera in Lobariaceae-is characterized by foliose thalli with pseudocyphellae, which generate microhabitats suitable for tardigrades. These microinvertebrates contribute to humification, decomposition, and food web dynamics. This study examined six Pseudocyphellaria … Read more...

Urbanavichus G.P. & Urbanavichene I.N. (2025): First records of nine species for the lichen flora of Russia from Utrish State Nature Reserve (the North-West Caucasus), Nature Conservation Research, 10(4): 92–94

This study is a contribution to the lichenological exploration of Protected Areas of the Russian Caucasus. Nine species of lichen and lichenicolous fungi (Agonimia octospora, Cercidospora caudata, Diplotomma glaucoatrum, Lichenochora aprica, Micarea herbarum, Opegrapha opaca, Sarcopyrenia geisleri, Toninia subdispersa, and Tremella macrobasidiata), collected mainly in the sub-Mediterranean formations in the Utrish State Nature Reserve on the Abrau Peninsula, have been reported for the first time … Read more...

Valitova J.N., Khabibrakhmanova V.R., Babayev V.M., Khajrullina A.F., Gurjanov O.P., Gazizova N.I., Beckett R.P. & Minibayeva F.V. (2025): Sterol composition in the lichens Lobaria pulmonaria and Lobaria retigera: Does photobiont matter?, International Journal of Molecular Sciences, 26(22): 11041 [10 p.]

The lipid composition of the mycobint and photobiont symbiotic partners of lichenized ascomycetes varies greatly. The aim of this study was to compare the profile of the major sterols in two closely related lichens from the genus Lobaria with different photobionts. The three-component lichen Lobaria pulmonaria has two photobionts. While the main photobiont is the chlorophycean alga Symbiochloris reticulata, this lichen contains small amounts of the cyanobacterium Nostoc. By contrast, the cyanobacterium … Read more...

Czacharowski M. & Bolibok L. (2025): The effect of gap size on the establishment and initial development of natural regeneration of Scots pine (Pinus sylvestris L.) in oligotrophic sites, European Journal of Forest Research, 144: 1701–1717

Artificial canopy gaps represent an effective tool for promoting natural regeneration, increasing structural diversity in forest ecosystems. However, the influence of specific gap characteristics on regeneration success remains insufficiently understood. This is especially important for the transformation of even-aged, single-layered Scots pine (Pinus sylvestris L.) stands on oligotrophic sites, where there is a clear need for evidence-based silvicultural recommendations. This study investigated … Read more...

Millanes A.M., Tuovinen Nogerius V., Freire-Rallo S., Diederich P., Periáñez J., Westberg M., Merinero S., Johannesson H. & Wedin M. (2025): Different patterns of frequency, lichen specificity and thallus location between the yeast and filamentous phases of two lichen-inhabiting basidiomycetes, Environmental Microbiology, 27(11): e70203 [16 p.]

Many fungi have a dimorphic life cycle, alternating between unicellular yeast and multicellular filamentous phases. Although dimorphism is assumed for many lichen-associated basidiomycetes, the existence of a yeast stage has rarely been confirmed. Using taxon-specific PCR and FISH-CLSM, we studied Tremella hypogymniae and T. tubulosae Tremellomycetes), two presumably dimorphic species previously known only from their filamentous phase in galls on the lichens Hypogymnia physodes and H. tubulosa, respectively. … Read more...

Diederich P., Lawrey J.D. & Ertz D. (2025): The 2025 classification and checklist of lichenicolous fungi: documenting a rapidly growing knowledge of diversity, Bryologist, 128(4): 765–870

Lichenicolous fungi comprise a diverse group of highly specialized organisms inhabiting lichens, occurring as parasites, commensals or saprotrophs, either host-specific or generalists. Since our 2018 checklist, the field has seen remarkable growth, notably through the publication of the first two volumes of the Flora of Lichenicolous Fungi (2022, 2024), which described numerous new species and genera of Basidiomycota and hyphomycetes. Here, we present an updated classification and checklist of lichenicolous … Read more...

Belosokhov A. & Spribille T. (2025): Making fungal-photobiont symbioses in the lab: Past, present, and future of the elusive in vitro lichen, Annual Review of Microbiology, 79(1): 713–730

The ability to synthesize lichen symbioses in vitro from pure cultures of transformable symbionts would be a game changer for experiments to identify the metabolic interplay that underpins the success of lichens. However, despite multiple reports of successful lichen resynthesis, no lichen lab model system exists today. We reviewed 150 years of in vitro lichen studies and found that the term resynthesis is applied to many types of fungal-photobiont cocultures that do not resemble lichens. Some of … Read more...

Nunes B.B.S., Braga A., Marques M.E.M., Lopes I. & Cardoso J.C.F. (2025): Are lichens biocompasses? Revisiting an old prediction using new techniques, Plant Biology, 27: 1150–1157

Abiotic factors influence not only vertical distributions of epiphytes, but also their radial positioning, such as around tree trunks. Due to planetary patterns of solar incidence, the equator-facing trunk portions receive direct sunlight, creating restrictive microclimatic conditions. Conversely, pole-facing portions remain shaded, providing optimal conditions for some epiphytes. Since trunk microhabitats are continuous, the distribution of epiphytes involves directional (compass-derived) data, … Read more...
