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...

Kumar V., Upreti D.K. & Nayaka S. (2024): Morpho-taxonomic revision of the lichen genus Psora Hoffm. (Psoraceae, Lecanorales) from India, Biology Bulletin, 51: 954–958

Three species of the genus Psora are recognized in India including Psora crenata (Taylor) Reinke, P. decipiens (Hedw.) Hoffm. and P. himalayana (C. Bab.) Timdal. Among them, P. crenata is described as a new record to the lichen biota of India. Descriptions, illustrations and distributions are provided for each species together with a key to all species of Psora known from India. Keywords: lichenized fungi, biodiversity, taxonomy, Himalaya.

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...

Fałowska P., Dziurowicz P., Waszkiewicz K., Kamiński A., Nicia P., Zadrożny P. & Węgrzyn M.H. (2026): Seasonal, microclimatic and edaphic determinants of Cladonia spp. stress physiology in dry sandy Scots pine lichen forests, Forest Ecology and Management, 612: 123732 [14 p.]

The Cladonio–Pinetum association is among Europe’s most endangered dry, sandy forest communities and is highly sensitive to microclimate and edaphic shifts. We quantified how seasonality and microhabitat (psammophilous grasslands vs. pine forests) modulate physiological traits of the dominant terricolous lichens Cladonia mitis and Cl. uncialis in Bory Tucholskie National Park (north-central Poland). From September 2022 to September 2023 we monitored six permanent sites, recording light, temperature, … Read more...

Hynniewta L. & Syiem M.B. (2026): Ultrastructural and metabolic modifications in the cyanobiont of a high-altitude symbiotic lichen Peltigera malacea from Meghalaya, India, Symbiosis, 98: 15–27

The lichen Peltigera malacea collected from Pynursula, East Khasi Hill district, Shillong, Meghalaya, India, situated at N: 25° 82’ 9.6” E: 92° 6’ 43” at an altitude of 1425 m above sea level was investigated. Morphological and ultrastructural studies showed the presence of a cyanobacterium Nostoc calcicola just below the upper cortex of the lichen thallus and in contact with the fungi. Biochemical analysis proved this symbiosis to be a bipartite, where the heterocyst frequency of the cyanobiont … Read more...

Lobakova E.S., Zaytseva A.A., Shibzukhova K.A., Butaeva G.B. & Gorelova O.A. (2026): Localization of cyanobacteria in cohabitations with moss Hylocomium splendens and lichen Nephroma arcticum of the Karelian coast of the White Sea and heir phylogenetic relationship, Russian Journal of Plant Physiology, 73: 42 [14 p.]

Cyanobacteria have a number of properties, such as the ability to photosynthesize and fix nitrogen, which contribute to their survival in the harsh climatic conditions of the White Sea coast, which makes them attractive to organisms of various kingdoms for creating associations. In this paper, we studied such cohabitations with the moss Hylocomium splendens and the three-component lichen Nephroma arcticum. Using light and scanning electron microscopy, elongated ellipsoid, less often spherical, primordia … Read more...
