Vasco-Palacios A.M., Lücking R., Moncada B., Palacio M. & Motato-Vásque V. (2022): A critical assessment of biogeographic distribution patterns of Colombian fungi - In: de Almeida R.F., Lücking R., Vasco-Palacios A.M., Gaya E. & Diazgranados M. (eds), Catalogue of Fungi of Colombia, p. 121–137, Kew Publishing, Royal Botanic Gardens, Kew

Book chapter. This chapter attempts to assess the distribution patterns of three selected groups of fungi, namely polypores, ectomycorrhizal fungi (EcM), and lichenised fungi in Colombia. Assessing the biogeography of fungi is difficult because of two key issues: 1. information gaps on their distribution and biology in biodiversity-rich countries, such as Colombia, and 2. the traditional, phenotype-based species concepts, which make it difficult to recognise cryptic species or species complexes. … Read more...

Frisch A., Ohmura Y., Holien H. & Bendiksby M. (2022): A phylogenetic survey of the ascomycete genus Arthrorhaphis (Arthrorhaphidaceae, Lecanoromycetes) including new species in Arthrorhaphis citrinella sensu lato - Taxon, 71(5): 936–962

The genus Arthrorhaphis is a group of ascomycetes comprising lichenised and non-lichenised taxa from temperate to arctic-alpine regions in both hemispheres. Nine species and two infraspecific taxa are currently recognised. Their delimitation, inter-relationships, and phylogenetic placement remain poorly understood. We have used an integrative taxonomic approach to assess taxon limits, phylogenetic placement of the family, and to test the hypothesis that transition to lichenisation has happened … Read more...

Lendemer J.C. & McMullin R.T. (2022): Lectotypification of the threatened endemic Appalachian lichen Alectoria fallacina - Taxon, 71(5): 1077–1083

Alectoria fallacina, described by the prolific 20th century lichenologist Josef Motyka, is a threatened species narrowly endemic to the Appalachian Mountains of eastern North America. The production of a unique unidentified fatty acid as the main secondary metabolite chemically separates A. fallacina from its congeners, especially the morphologically similar A. sarmentosa. Here we show that while A. fallacina and A. sarmentosa are entirely allopatric, the type collection of A. fallacina is a mixture … Read more...

Rocha B., Matos P., Giordani P., Lõhmus P., Branquinho C., Casanelles-Abella J., Aleixo C., Deguines N., Hallikma T., Laanisto L., Moretti M., Alós Ortí M., Samson R., Tryjanowski P. & Pinho P. (2022): Modelling the response of urban lichens to broad-scale changes in air pollution and climate - Environmental Pollution, 315: 120330 [10 p.]

To create more resilient cities, it is important that we understand the effects of the global change drivers in cities. Biodiversity-based ecological indicators (EIs) can be used for this, as biodiversity is the basis of ecosystem structure, composition, and function. In previous studies, lichens have been used as EIs to monitor the effects of global change drivers in an urban context, but only in single-city studies. Thus, we currently do not understand how lichens are affected by drivers that … Read more...

Kalın Ş.N., Altay A. & Budak H. (2022): Inhibition of thioredoxin reductase 1 by vulpinic acid suppresses the proliferation and migration of human breast carcinoma - Life Sciences, 310: 121093 [11 p.]

Aims It was aimed to investigate the thioredoxin reductase 1 (TrxR1)-targeted anticancer effect of vulpinic (VA) and lecanoric (LA) acids, which are lichen secondary metabolites, on breast cancer MCF-7 and MDA-MB-453 cell lines, and to compare the effectiveness of this potential effect against commercial chemotherapeutic drugs carboplatin and docetaxel. Main methods The anticancer effects of both lichen metabolites were evaluated by XTT, flow cytometry analysis, cell scratch, and transwell … Read more...

(2022): Cladonia verticillaris (lichen) can exhibit defense mechanisms against Rn-222 under controlled conditions - Journal of Radioanalytical and Nuclear Chemistry, 331: 3671–3679

This study aimed to evaluate the efects of the Rn-222 progeny on the lichen Cladonia verticillaris under controlled conditions. The results showed resistance of the species, and few changes in the level of photosynthetic pigments. Blockage in the biosynthetic route of the major phenolic compound fumarprotocetraric acid was also identifed, and accumulation of protocetraric acid, as defense mechanism against external pollutants, to maintain thallus vitality. The accumulation of the 210Pb and … Read more...

Kuusisto I. & Mattanen S. (2022): Caloplaca tornoënsis new to Finland - Graphis Scripta, 34(6): 54–58

Caloplaca tornoënsis is reported from Finland for the first time. Specimens were collected from five locations of NW Finland and from one location of NE Finland. Collections were made from snowbeds on bryophytes using transect plot-based sampling method. C. tornoënsis has a circumpolar distribution and it is probably overlooked, although a rare species in Finland. The species should be looked for in late melting areas of mountains of northernmost Finland. Read more...

He Z. & Naganuma T. (2022): Chronicle of research into lichen-associated bacteria - Microorganisms, 10(11): 2111 [15 p.]

Lichens are mutually symbiotic systems consisting of fungal and algal symbionts. While diverse lichen-forming fungal species are known, limited species of algae form lichens. Plasticity in the combination of fungal and algal species with different eco-physiological properties may contribute to the worldwide distribution of lichens, even in extreme habitats. Lichens have been studied systematically for more than 200 years; however, plasticity in fungal–algal/cyanobacterial symbiotic combinations … Read more...

Di Nuzzo L., Canali G., Giordani P., Nascimbene J., Benesperi R., Papini A., Bianchi E. & Porada P. (2022): Life-stage dependent response of the epiphytic lichen Lobaria pulmonaria to climate - Frontiers in Forests and Global Change, 5: 903607 [14 p.]

Lichens are poikilohydric organisms, whose internal water content tends to reflect external humidity conditions. After drying, they can reactivate their metabolic activity through water vapor uptake or liquid water input. Thus, lichen water-related functional traits are important as they are involved in the duration of the hydrated period. Models predicting the effect of environmental conditions on lichens are based mainly on the presence or absence of adult thalli. Nevertheless, ecological … Read more...
