Ohmura Y., Tadome K., Kubo K. & Miyazawa K. (2026): Lichen diversity in the Imperial Palace Grounds, Tokyo, Japan, based on the third biodiversity survey, Memoirs of the National Museum of Nature and Science [Tokyo], 53: 65–105

An inventory of lichens in the Imperial Palace Grounds, Tokyo, Japan, conducted between 2021 and 2025, identified a total of 110 taxa of lichens and allied fungi, comprising 66 genera, 82 species, and 28 taxa identified only to the genus level. These included three lichenicolous fungal taxa (three genera) and one non-lichenized fungal taxon. When combined with previous surveys conducted in 1995–1996 and 2009–2013, the cumulative number of taxa recorded from the area reaches 145 taxa (77 genera, … Read more...

Ansil P.A., Rajeshkumar K.C. & Lücking R. (2026): Thelotrema maharashtrense (Graphidaceae), a new lichen-forming species from the Western Ghats of India, Phytotaxa, 752(3): 185–196

This study describes a new lichenized species, Thelotrema maharashtrense, from the Western Ghats of Maharashtra, India, integrating morphological, chemical, and phylogenetic methods. Thelotrema maharashtrense is characterised by a loosely corticate thallus, prominent apothecia with an only rarely apically free, basally I+ amyloid exciple, 1-spored asci producing large, muriform ascospores, and lack of lichen substances. Analyses based on a concatenated mtSSU, LSU and rpb2 data set placed T. maharashtrense … Read more...

Ferron S., Ismed F., Elyashberg M.E., Buevich A.V., Arifa N., Boustie J., Uriac P., Le Pogam P. & Le Dévéhat F. (2024): CASE-DFT structure elucidation of proton-deficient chlorodepsidones from the Indonesian lichen Teloschistes flavicans and structure revision of flavicansone, Journal of Natural Products, 87: 2148−2159

Biodiscovery efforts in Indonesia have aimed to explore the understudied chemical diversity of its rich lichen flora, seeking to find new products endowed with significant biological properties. The chemical screening of a Teloschistes flavicans extract led to selection of this species for further investigation. LC/MS and 1H NMR-based dereplication pinpointed six chlorodepsidones from the thallus of a sample of this lichen. This led to the streamlined isolation and the subsequent structure elucidation … Read more...

Millot M., Tomasi S., Studzinska E., Rouaud I. & Boustie J. (2009): Cytotoxic constituents of the lichen Diploicia canescens, Journal of Natural Products, 72: 2177–2180

A new diphenyl ether (1), along with 12 known compounds, was isolated from the lichen Diploicia canescens. The structure of compound 1 was elucidated by spectroscopic data analysis, and the biosynthetic origin of this product is discussed. Secalonic acids B (7), D (8), and F (9) were isolated for the first time from D. canescens. The cytotoxic activities of 1−3, 6−8, and 10 against the B16 murine melanoma and HaCaT human keratinocyte cell lines were evaluated. Read more...

Devi A.P., Duong T.-H., Ferron S., Beniddir M.A., Dinh M.-H., Nguyen V.-K., Pham N.-K.-T., Mac D.-H., Boustie J., Chavasiri W. & Le Pogam P. (2020): Salazinic acid-derived depsidones and diphenylethers with α-glucosidase inhibitory activity from the lichen Parmotrema dilatatum, Planta Medica, 86(16): 1216–1224

Three new depsidones, parmosidones F – G (1 – 2), and 8′-O-methylsalazinic acid (3), and 3 new diphenylethers, parmetherines A – C (4 – 6), together with 2 known congeners were isolated from the whole thalli of Parmotrema dilatatum, a foliose chlorolichen. Their structures were unambiguously determined by extensive spectroscopic analyses and comparison with literature data. The isolated polyphenolics were assayed for their α-glucosidase inhibitory activities. Newly reported … Read more...

Masyagina O.V., Evgrafova S.Yu., Detsura A.E., Porfirieva E.V., Sitnikova M.V., Kovaleva N.M., Menyailo O.V. & Matvienko A.I. (2026): Unearthing current knowledge gaps in epiphytic lichen research: A bibliometric analysis, Journal for Nature Conservation, 92: 127296 [15 p.]

Epiphytic lichens (ELs) are widespread symbiotic organisms (consortia of algae, cyanobacteria, fungi, yeasts, and bacteria) crucial to the cryptogamic cover of woody plants and could significantly influence carbon cycling under climate change. This study provides a scientometric analysis (using R and VOSviewer) of 1796 Scopus publications (1950–2023) to assess research trends on ELs, including their role in greenhouse gas exchange. The study revealed the following key findings:●Approximately … Read more...

Lichens have long been recognized for their therapeutic potential in traditional medicine; however, their secondary metabolites remain far less explored pharmacologically compared to plant-derived bioactive compounds. This review aims to highlight the chemistry and pharmacological applications of the lichen metabolite vulpinic acid (VA). Relevant literature was retrieved from scientific databases including Scopus, PubMed, and Google Scholar using the keyword “vulpinic acid,” and additional information … Read more...

Moriyama T., Endo C., Isagi Y., Tanaka C., Ohkuma M. & Hashimoto A. (2026): Rediscovery of “Gloeocystis-Halbflechte” after 84 years revealed an independent lineage of ascomycetes harboured in gelatinous algal biofilms, Fungal Biology, 130(4): 101757 [10 p.]

Gloeocystis-Halbflechte refers to a variant of the interactive structure between fungi and terrestrial unicellular green algae in which fungi form haustoria in algal cells within gelatinous algal colonies and occasionally form monilioid hyphal outgrowth. It was first recognized in 1941; however, the identity of the fungal and algal components of this interaction has not been clarified. In this study, the interactive structure between fungi and algae resembling Gloeocystis-Halbflechte and the adjacent … Read more...

Luo D., Cheng K., Wang Y., Xie T. & Yang R. (2026): The transport and distribution of polycyclic aromatic hydrocarbons (PAHs) across the Hengduan Mountains, southwest China, Forests, 17(4): 502 [14 p.]

Despite recent advances in polycyclic aromatic hydrocarbon (PAH) research on the Tibetan Plateau (TP), studies investigating the transport potential and accumulation dynamics of these contaminants in the Hengduan Mountains, especially in forest soils which are important sinks for atmospheric PAHs, remain scarce. In the present study, soil and lichen samples (partially located under the forest canopy) were concurrently collected from 62 sampling sites across the Hengduan Mountains to characterize … Read more...
