Paukov A. G., Davydov E. A., Kuzmina I. A., Chusovitin A. A., Ren Q. & Sohrabi М. (2023): Diversity and preliminary phylogeny of ‘Circinaria transbaicalica’ group (lichenized Ascomycetes), Problems of Botany in South Siberia and Mongolia (Проблемы ботаники Южной Сибири и Монголии), 22(2): 248-250

Circinaria transbaicalica – is a saxicolous dwarf-fruticose lichen species, with a range spreading from the Trans-Baikal territory and China to the Ural Mountains. The study of ITS and mtSSU sequences showed that it is relative to the crustose Circinaria arida, previously known from the USA only, and to the radiate C. maculata described from China. Specimens determined as Circinaria transbaicalica were split into two separate branches likely representing cryptic species that have no distinct … Read more...

Iqbal M. S., Din A. U., Khalid A. N. & Niazi A. R. (2024): A new species in the lichen genus Circinaria (Megasporaceae) from Pakistan based on morphology and DNA sequence data, Journal of the Botanical Research Institute of Texas, 18(2), 333–340

Circinaria terrenoides sp. nov. was collected in Balochistan and Gilgit Baltistan. Comparative morpho-anatomical research, chemical analysis, and ITS-based DNA analyses all support its placement within the genus Circinaria. Circinaria terrenoides sp. nov. is distinguished from the closely related species C. affinis in having a crustose, areolate to rimose-areolate thallus (vs. subfruticose, verrucose-areolate), earthy brown to greenish gray upper surface (vs. earthy gray to gray-green), smaller conidia … Read more...

Sipman H.J.M. & Raus T. (2026): Annotated lichen list for the island of Astipalea (central Aegean, Greece), including taxonomic and chorological novelties, Willdenowia, 56: 225–247

We report 152 species of lichenized and lichenicolous fungi from the central Aegean island of Astipalea, Greece, based on morphological, anatomical, chemical and macromolecular examination. Amandinea oleicola, Arthonia sanguinea and Endocarpon latzelianum are reported for the first time from Greece. Glaucomaria sulphurata and Lepra parotica are introduced as new combinations. Ramalina aegaea is described as a species new to science because its ITS sequences deviate from the morphologically similar … Read more...

McIlroy de la Rosa J.P., Warke P.A. & Smith B.J. (2014): The effects of lichen cover upon the rate of solutional weathering of limestone, Geomorphology, 220: 81–92

The contribution of lichens to the biomodification of limestone surfaces is an area of conflict within bioweathering studies, with some researchers suggesting a protective effect induced by lichen coverage and others a deteriorative effect induced by the same organisms. Data are reported demonstrating the potential role of endolithic lichen, in particular of Bagliettoa baldensis, in the active protection of Carboniferous limestone surfaces from rainfall-induced solutional weathering. During a 12-month … Read more...

Мелехин А.В. [Melekhin A.V.] (2026): Новые для Мурманской области виды на северной границе распространения [Lichens new for the Murmansk Region at the northern limit of distribution] , Труды Карельского научного центра РАН, Серия "Биогеография", Петрозаводск [Transactions of the Karelian Research Centre of Russian Academy of Science, ser. Biogeography, Petrozavodsk], 2026/3: 142–145

[in Russian with English abstract: ] Three lichen species previously unknown for the Murmansk Region are reported at the northern limit of their distribution and away from areas with their concentrated populations: Lecania naegelii, Porina lectissima, and Psora testacea. Porina lectissima was found in the northeast of the region, and the other two in the Khibiny Mountains. All the species are common in southerner regions of the world. Keywords: lichens; new records; calcicolous species; Murmansk … Read more...

Do T.-H., Duong T.-H., Ho M.-T.-T., Pham D.-D., Nguyen T.-H.-M., Aonbangkhen C., Sichaem J., Nguyen C.H.,, Vo T.-P.-G., Nguyen N.-H. & Tran T.-M.-D. (2026): A new diphenyl ether from the cultured lichen mycobiont of Graphis cf. handelii, Natural Product Research, 40: 189–195

Lichen is well-known for its various purposes. However, understanding the chemical composition and antimicrobial characteristics of Graphis cf. handelii remains insufficient. In this study, a new compound, graphinone A (1), together with three known compounds, handelone (2), 4-O-methylhiascic acid (3), and ethyl orsellinate (4) were isolated and structurally elucidated. Their chemical structures were established using comprehensive spectroscopic data (1D- and 2D-NMR and HRESIMS). Compounds 1–4 … Read more...

Huneck S., Porzel A. & Schmidt J. (1993): Structure and synthesis of arthonin, a lichen metabolite from Arthonia endlicheri, Tetrahedron: Asymmetry, 4(3): 303–311

Arthonin, a metabolite of the lichen Arthonia endlicheri has been structurally elucidated as (−)-N-benzoyl-L-valinyl N′-benzoyl-L-isoleucinate. The syntheses of arthonin and iso-arthonin [(−)-N-benzoyl-L-isoleucyl-O-benzoyl-L-valinol] are described. Arthonin (1) has been structurally elucidated as (−)-N-benzoyl-L-valinyl N′-benzoyl-L-isoleucinate. The syntheses of arthonin and iso-arthonin (2) are described. Read more...

Purpose: Cultured lichen mycobionts are valuable sources of new natural compounds. Mycobiont of Graphis handelii growing in Vietnam was isolated, cultivated and chemically investigated. The crude extract of this cultured mycobiont showed potent alpha-glucosidase inhibition with an IC50 value of 50 μg/mL. Methods: Multiple chromatographic methods were applied to the extract to isolate compounds. The combination of Nuclear Magnetic Resonance analysis and high-resolution mass spectroscopy determined … Read more...

Martellos S., Seggi L. & Trabucco R. (2026): The dataset of the lichen collection "Abramo Massalongo" preserved at the Natural History Museum of Venice, Biodiversity Data Journal, 14: e184587 [12 p.]

Background: Italy was one of the most active countries in the field of lichenology in the nineteenth century. Researchers such as Baglietto, De Notaris, Massalongo and Trevisan produced relevant herbaria, which are (at least in part) still preserved today. The digitisation of at least some of the collections is allowing the mobilisation of information from these specimens and aggregating the metadata in national and global repositories. New information: This dataset contains the metadata and images … Read more...
