It was discovered on February 22, 2020 on Quercus in a former clay pit at Rumst (Terhagen, province of Antwerp, Belgium). Morphology, ecology, habitat and distribution of the species are described.

Ertz D. (2024): Quatre espèces de lichens et deux espèces de champignons lichénicoles nouvelles pour la Belgique, et d’autres espèces intéressantes pour le pays, Dumortiera, 124: 28–33

Four species of lichens and two species of lichenicolous fungi new to Belgium, and other species of interest for the country. Recent field surveys have yielded several species of lichens and lichenicolous fungi that are interesting or new to Belgium. Species new to Belgium are: Chaenothecopsis pusiola, Inoderma byssaceum, Rinodina biloculata, Porina rosei, Verrucula pusillaria and Xenonectriella physciacearum. Other species of interest for Belgium: Arthonia fuscopurpurea, Melanelia stygia and … Read more...

Hjelm K., Romans E., Högbom L. & Ring E. (2025): Tree growth and ground vegetation 17 years after disc trenching and pre-harvest nitrogen fertilization, Forest Ecology and Management, 597: 123145 [10 p.]

Silvicultural practices such as site preparation and nitrogen (N) fertilization are commonly used to increase growth of a stand. These practices may affect the forest ecosystem for several decades, impacting not only the trees, but also the stand structure and ground vegetation. Long-term field experiments are thus necessary to study these effects. In our study, two field experiments, Hagfors and Nissafors, established around 1980, were used to study residual effects of previous N-fertilization and … Read more...

Wallenius T., Bjerke J.W., Erlandsson R., Kolari T.H.M., Räsänen A., Tahvanainen T., Tømmervik H., Winquist E. & Virtanen T. (2025): Reconstructing the historical decline of lichen cover across the reindeer fence of the Finnish–Norwegian border, Ambio, 54: 1683–1704

We analysed the history behind the current contrasting lichen covers of two adjacent reindeer herding districts at the Finnish–Norwegian border. We conducted vegetation field inventories across the border fence and reconstructed a lichen cover history from 1959 to 2020 using aerial and satellite images. The oldest images showed only a slight difference in lichen cover between the different sides of the border fence. Since the late 1950s, lichen cover has decreased in both districts. At present, … Read more...

Lin Y.-Y., Ho H.-C. & Chou J.-Y. (2025): Effects of lichen symbiotic bacteria-derived indole-3-acetic acid on the stress responses of an algal–fungal symbiont, Brazilian Journal of Microbiology, 56: 1567–1584

Lichens, comprising filamentous fungi and algae/cyanobacteria engaged in mutualistic symbiosis, exhibit remarkable adaptability to environmental challenges. While fungi safeguard algae from dry conditions, their ability to mitigate other stresses remains uncertain. Additionally, the functions of coexisting bacteria within lichen communities remain relatively unexplored. This study investigates the potential of indole-3-acetic acid (IAA) as a stress-response signaling molecule in lichen symbiosis. … Read more...

Gasulla F., Casano L.M. & Pérez-Ortega S. (2025): Algae and the city: the genetic and ecophysiological diversity of photobionts in two areas of Madrid (Spain) with contrasting levels of nitrogen pollution, Environmental Science and Pollution Research, 32: 17978–17996

Diverse hypotheses have been proposed to explain the low diversity and abundance of lichens in large cities, including high nitrogen pollution and the heat-island effect. Furthermore, it remains unclear which partner, the mycobiont or the photobiont, is more affected by these stresses that limit lichen survival. This study aimed to explore how nitrogen pollution and xeric conditions affect lichen photobionts. Photobionts from 25 lichen species in seminatural and urban areas of Madrid (Spain) were … Read more...

Knudsen K., Kocourková J., Kondrysová E., Pušová T., Hollinger J., Leavitt S., McCarthy J., Jedličková L. & Westberg M. (2025): Discovering the diversity of Acarosporaceae (Acarosporales, Lecanoromycetes) with carbonized epihymenial accretions in North America, MycoKeys, 122: 123–148

Six new species are described: Acarospora anthracina, A. austrooccidentalis, A. oscurensis, and A. profusa from southwestern North America; A. aquatica from wetlands in eastern North America; and A. minuta from the Holarctic flora of Canada. In total, 13 species of Acarosporaceae with carbonized epihymenial accretions are known from North America. No European taxa of Acarospora or Sarcogyne with carbonized epihymenial accretions were found in North America, except A. lapponica, which is part of the … Read more...

Ertz D. (2023): Les lichens et les champignons lichénicoles de la vallée de la Semois entre Bouillon et Bohan, avec dix-neuf espèces nouvelles pour la Belgique, Dumortiera, 121: 18–44

The lichens and lichenicolous fungi of the Semois valley between Bouillon and Bohan, with nineteen species new to Belgium. 335 species of lichens and 24 species of lichenicolous fungi were recorded during inventories carried out between 2020 and 2023 in the section of the Semois valley between Bouillon and Bohan. Nineteen species are new to Belgium: Abrothallus caerulescens, Arthonia digitatae, A. graphidicola, Bacidina piceae, Chaenothecopsis ochroleuca, Cresponea premnea, Dirina fallax, Lecanora … Read more...

Jones F.A.M., Hardenbol A.A., Hekkala A.-M., Larsson Ekström A., Jönsson M., Koivula M., Strengbom J. & Sjögren J. (2025): Partitioning beta diversity at two spatial resolutions reveals biotic homogenisation with habitat degradation, Diversity and Distributions, 31: e70080 [14 p.]

Aim: Understanding the effects of habitat degradation on biodiversity is essential for undertaking conservation initiatives, but commonly used metrics of biodiversity, like species richness and beta diversity, can miss important signals of change. Greater insights can be gained by partitioning beta diversity into nestedness, which relates to species loss, and turnover, which relates to species replacement. To obtain a more comprehensive understanding of biodiversity change with habitat degradation, … Read more...
