Kalın Ş.N. (2026): Evernic and diffractaic acids: Novel regulators of intracellular redox homeostasis in the MCF-7 cell line, Molecular Biology Reports, 53: 1182 [13 p.]

Background: Oxidative stress plays a critical role in tumor development and cancer cell survival; however, the effects of lichen secondary metabolites on antioxidant defense systems are not yet fully understood. In our previous study, we demonstrated that the lichen secondary metabolites evernic acid (EA) and diffractaic acid (DA) exert significant cytotoxic and anti-migratory effects in MCF-7 breast cancer cells through inhibition of thioredoxin reductase 1 (TrxR1), a key oxidoreductase enzyme involved … Read more...

Singh P. (2026): Resolving axonomic ambiguity in the Graphidaceae: Phaeographina torquescens and Sarcographina subtorquescens are synonyms of Sarcographa glyphiza, Phytotaxa, 767(2) 197–203

The taxonomic identity of the type material of Phaeographina torquescens (basionym: Glyphis torquescens) and Sarcographina subtorquescens (basionym: Glyphis subtorquescens) housed at the Finnish Museum of Natural History, Helsinki (H-NYL) is critically re-evaluated and found to be conspecific with Sarcographa glyphiza. Henceforth, both taxa are synonymized under S. glyphiza. This taxonomic revision is based on a thorough examination of all available type specimens, including detailed morphological, … Read more...

Maglonzo J.R.M., Ohmura Y. & dela Cruz T.E.E. (2026): A taxonomic report of Usnea from Quezon, Luzon Island, Philippines, Acta Manilana, 74: 17–28

The fruticose lichen Usnea is a globally distributed group. However, its diversity in many parts of the Philippine archipelago remains poorly documented. This study reports a taxonomic account of Usnea from two localities of Quezon Province, Luzon Island, Philippines: Mt. Banahaw de Tayabas and Brgy. Sitio Pandak, Lucban. Six specimens were collected and examined based on morphological, anatomical, and chemical characters. Major lichen substances were identified by thin-layer chromatography. … Read more...

Chiva S., Pazos T., Montero-Pau J., Moya P., Garrido-Benavent I., Barreno E. & Muggia L. (2026): Symbiotic versatility in action: Trebouxia diversity expands the niche of the lichen Xanthoria parietina, Environmental Microbiology, 28(7): e70379 [19 p.]

Xanthoria parietina is one of the most widespread and ecologically versatile lichens, yet the diversity of its fungal and algal symbionts and their contribution to its broad ecological niche remain poorly understood. Genetic diversity and phylogenies of both lichen symbionts were inferred from nrITS data. Mycobiont–phycobiont interaction networks were constructed, and ecological niches of associated Trebouxia species were modelled using 19 bioclimatic variables. Phylogenetic analyses revealed high … Read more...

(2026): Forest structure and multi-taxonomic diversity in Apennine beech forests subjected to conservation-oriented interventions, Plant Biosystems, 160: 224 [12 p.]

European forests have a long history of management, which has often homogenized stand structure, impacting the diversity of forest biological communities. In the last decades, the pursuit of forest multifunctionality has put emphasis on the links between forest management, structure and biodiversity. However, the lack of integrated data on stand structure and multi-taxon biodiversity data has hampered the understanding of how changes in forest structure affect the composition of different taxonomic … Read more...

We report 60 strictly or facultatively lichenicolous fungi including lichenicolous lichens as new to Padjelanta National Park. Among these, 20 species are new to Sweden, including one described new to science, one new to Europe and five new to Fennoscandia. The material was collected in Padjelanta National Park in 2020, 2022 and 2024. Stigmidium sapmi Isaksson & R.Vicente is described as new to science. The other species that are new to Sweden are: Arthonia epipolytropa, Chaetopyrena penicillata, … Read more...
