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...

Maliniemi T., Kiilunen P., Bråthen K.A., Kapfer J., Rosendal T.B., Grytnes J.-A., Saccone P. & Virtanen R. (2025): Long-term homogenization of Fennoscandian heathland and tundra vegetation is connected to the expansion of an allelopathic dwarf shrub, Ecography, 2025: e07921 [14 p.]

Boreal and tundra plant communities are expected to change in biodiversity due to increasing global change pressures such as climate warming. One long-term scenario is increasing compositional similarity, i.e. biotic homogenization, which has been relatively little studied in high-latitude plant communities. Here, we study how the composition and diversity of heathland and tundra plant communities have changed in northern Fennoscandia over several decades. In 2013–2023, we resurveyed 275 historic … Read more...

Roos U., Adler S., Lind T. & Sandström P. (2025): Ground lichen cover and response in relation to forest characteristics in Sweden 1993–2023, Global Ecology and Conservation, 64: e03946 [16 p.]

Reindeer husbandry is closely connected to the culture and tradition of the indigenous Sami people, and ground lichens are a key bottleneck resource for winter grazing of the semi-domesticated reindeer. Many factors have been linked to the decrease in ground lichens in the boreal zone. Forestry plays a crucial role in the lichen decline in Swedish forests but is also an important actor with the potential to contribute to a recovery. Forestry is obliged to consider the needs of reindeer husbandry, … Read more...

Nascimbene J., Di Musciano M. & Gheza G. (2025): Resampling epiphytic lichens in coniferous forests of the Southern Alps: Veteran trees promote compositional stability, Perspectives in Plant Ecology, Evolution and Systematics, 69: 125904 [8 p.]

In this study, by means of resampling epiphytic lichens in a timespan of fifteen years in forest stands of the Paneveggio-Pale di San Martino Natural Park (N Italy – Southern Alps), we aim at detecting changes in lichen assemblages by comparing temporal β-diversity patterns between tree individuals of different ages and considering the response pattern of thallus growth forms. Our results indicate that on veteran trees lichen composition seems to be more stable over time. This view is corroborated … Read more...
