Rajaprabu N., Vasanthakumar A., Ponnusamy P., Govindarajan R.K., Alhomaidi E., Alsubait J., Rabbee M.F., Piskov S., Rzhepakovsky I. & Nagdalian A. (2026): Lichen-derived secondary metabolites and endophytic fungi as novel antidiabetic leads: Xylaria curta extract preserves β-cell viability and SUR1-mediated glucose sensing, 3 Biotech, 16: 393 [18 p.]

Type 2 diabetes mellitus (T2DM), driven by progressive pancreatic β-cell dysfunction and impaired insulin secretion, is a major global health burden, and new antidiabetic leads with β-cell-protective potential are needed. The sulfonylurea receptor 1 (SUR1), which gates ATP-sensitive potassium channels controlling pancreatic β-cell insulin release, is a validated but still underexploited antidiabetic drug target. Natural products derived from lichens and their associated endolichenic fungi (ELF) … Read more...

Beck A., Bayer C., Debastiani R., Schubert T., Gröger A. & Ruthensteiner B. (2026): Elemental composition, structure and amount of contact between Xanthoria parietina symbionts, Scientific Reports, 16: 27379 [9 p.]

As prominent examples for symbiotic interactions, the major part of lichens is built up by two different organisms, a photosynthetically active alga (photobiont) and a heterotrophic fungus (mycobiont). Given the hydrophobic coating of lichen symbionts in the lichen thallus by hydrophobins, the area of direct cell cell contact is of prime importance for the transfer of nutrients and signalling compounds between the symbionts. Genomic analyses reported cell wall remodelling during symbiont interaction. … Read more...

Gauslaa Y. (2026): Environmental, reproductive, and nutrient drivers of three-dimensional growth in the forest lichen Lobaria pulmonaria, Oecologia, 208: 122 [13 p.]

Measuring growth dynamics has been fundamental to understanding lichen biology and ecology. In this integrative analysis, I synthesize and reanalyze published data on three-dimensional growth in the foliose cephalolichen Lobaria pulmonaria transplanted in pristine North American forests, encompassing thallus area expansion, biomass accumulation, thallus thickening, and reproductive investment across multiple environmental gradients. Best subset regression selection and linear mixed models were applied … Read more...

Liu C. & Guo S. (2026): Optimal partitioning for molecular phylogenetic inference and generic delimitation in the cetrarioid core group (Parmeliaceae, Ascomycota), Journal of Fungi, 12(9): 654 [23 p.]

The species diversity of lichenized fungi remains largely underestimated, yet the number of species in the cetrarioid core group of Parmeliaceae has remained stable while generic delimitations have been highly debated. Here, we performed a partitioned phylogenetic analysis incorporating secondary structure characters of three ribosomal loci (ITS, mtSSU, and nuLSU) combined with comprehensive phenotypic traits. Based on the results, we hypothesized that a Large Temporal Band (29.0–35.0 Mya) may … Read more...

Moriyama T., Handa S., Sugiyama Y., Endo C., Tanaka C. & Isagi Y. (2026): Examples of diverse lichen-associated lifestyles of terrestrial algae Trentepohlia, Symbiosis, 98: 215–228

The present study reports for the first time that lichen thalli and ascomata may function as habitats for some trentepohliacean algae, including two new species described here, expanding the phylogenetic and ecological diversity in this algal lineage. Thorough sampling of Trentepohlia with various ecological traits was conducted at a single site, and the collected algae were morphologically and phylogenetically examined. Three species of Trentepohlia were revealed to inhabit lichens that are lichenized … Read more...

Sokolova I.V. & Stepanchikova I.S. (2026): Lectotypification of Parmelia pseudosaxatilis (Parmeliaceae). – In: Sokolova I.V. et al., Cryptogamic nomenclatural notes. 11, Новости систематики низших растений [Novosti sistematiki nizshikh rastenii] / Novitates systematicae plantarum non vascularium, 60(2): N4–N5

Parmelia pseudosaxatilis, when published, might be treated either as a replacement name or as the name of a new taxon. The typification carried out here (lectotype: W0347964) has established its status as a replacement name for P. marmariza var. physcioides. Keywords: lichen, lectotype, taxonomy, Parmelia.

Gagarina L.V., Komarnitskaya N.A. & Zueva A.S. (2026): Lectotypification of Usnea intermedia (Parmeliaceae). – In: Sokolova I.V. et al., Cryptogamic nomenclatural notes. 11 , Новости систематики низших растений [Novosti sistematiki nizshikh rastenii] / Novitates systematicae plantarum non vascularium, 60(2): N1–N4

Usnea intermedia was described from Italy by A. Massalongo in 1856 as U. barbata var. intermedia. The lectotype designated here is stored in the herbarium LE, isolectotypes in BM, BOLO, DUB, FH, NY, TO, UPS. Usnea intermedia is most similar to U. florida distinguishing mainly by its chemistry and spore size. Keywords: lichen, lectotype, taxonomy, Usnea. Read more...

Гудкова Е.П. & Мучник Е.Э. [Gudkova E.P. & Muchnik E.E.] (2026): Лихенобиота Приокско-Террасного государственного заповедника (Московская область, Россия)Lichen biota of the Prioksko-Terrasny state nature reserve (Moscow region, Russian federation) [Lichen biota of the Prioksko-Terrasny state nature reserve (Moscow region, Russian federation)], Вопросы лесной науки [Forest Science Issues], 9(2): 194 [39 p.]

[in Russian with Englisg abstract: ] Relevance and Goal. The Prioksko-Terrasny State Nature Biosphere Reserve, with an area of 4945 ha, is in the Serpukhovsky District of the Moscow Region, in the southern part of the coniferous-broadleaved forest subzone. The lichen biota of the territory has been studied only partially until now. This work aims to update and expand the list of lichens and allied fungi in the State Reserve, as well as to conduct a brief analysis of the identified lichen biota. … Read more...

Potenza G., Breuss O., Gheza G., Di Nuzzo L., Puntillo D., Isocrono D., Fascetti S. & Rosati L. (2026): Siliceous outcrops host new records of biodiversity interest for arctic–alpine lichens in the southern Apennines: An assessment based on field surveys and herbarium data, Diversity, 18(9): 521 [19 p.]

The Calabrian–Lucanian Apennines are a lichenologically insufficiently explored area. The purpose of the study was to improve the knowledge of its lichen flora in the wider context of ecology and biogeography and with regard to conservation perspectives. Our study is primarily based on recent collections but also includes comparative analyses of previous herbarium samples to verify identity; in particular a direct comparison with the CLU Herbarium (Calabria University) HLUC (Basilicata University) … Read more...

de Jonge I.K., Huisman S.N., Convey P., Cornelissen J.H.C. & Bokhorst S. (2026): Functional traits help identify remote sensing blind spots in polar vegetation mapping, Ecological Indicators, 189: 115107 [11 p.]

Accurate estimates of vegetation cover underpin ecological monitoring and conservation, yet lichens, the dominant primary producers across the coldest biomes remain poorly represented. Recent satellite-derived products provide Antarctic-wide estimates of vegetation cover, but detecting lichens remains challenging due to unique spectral characteristics, making it unclear where and how much lichen cover is missed. Interpreting and validating these products requires understanding of how lichens and … Read more...
