Kossowska M., Fałtynowicz W., Kowalewska A. & Piedgoń A. (2025): Lichens of the Ujście Warty National Park, Acta Mycologica, 60: 215424 [11 p.]

The first checklist of lichens occurring in the Ujście Warty National Park and its buffer zone is presented. The list is based primarily on the research conducted in years 2022–2024, but incorporates also the earlier literature data. During the research 138 lichen taxa were recorded, including 122 within the boundaries of the national park and 81 in its buffer zone. They represent various habitat groups: epiphytes (63 species), epixyles (59 species), epigeits (31 species), epiliths (39 species, … URL EN Read more...

Nguyen T.T.T., Chollet-Krugler M., Lohézic-Le Dévéhat F., Rouaud I. & Boustie J. (2015): Mycosporine-like compounds in chlorolichens: Isolation from Dermatocarpon luridum and Dermatocarpon miniatum, and their photoprotective properties, Planta Medica Letters, 2(1): e1-e5

Two mycosporines were isolated for the first time in two chlorolichen species, Dermatocarpon luridum and Dermatocarpon miniatum. Mycosporine glutaminol (1) and mycosporine glutamicol (2) were isolated along with the ethyl ester of mycosporine glutamicol (3), which was formed during the purification process. Aqueous extracts and pure mycosporines were then investigated for their antioxidant activities and photoprotective properties along with their photostability and photocytotoxicity. Semi-purified … URL EN Read more...

Mendonça S.C.S., de Vasconcelos C.M.L., Cruz J.S., Roman-Campos D., Menezes-Filho J.E.R., Anjos-Neto R.A., Martins D.L.C., Araújo A.A.S., da Silva L.C.C., Bezerra M.S., de Albuquerque-Júnior R.L.C. & Conde-Garcia E.A. (2017): (+)-usnic acid isolated from the lichen Cladonia substellata impairs myocardial contractility, Planta Medica International Open, 4: e59–e65

The scientific interest in (+)-usnic acid has grown because of its antitumor, cytotoxic, and antimicrobial activities as well as weight loss. However, overuse of usnic acid has been related with severe hepatotoxicity, making its use questionable. In this study, we decided to expand the knowledge of usnic acid biological activities by characterizing its effects on the mammalian myocardium as a potential pharmacological target. Usnic acid was isolated from samples of Cladonia substellata and submitted … URL EN Read more...

Ureña-Vacas I., González-Burgos E., Divakar P.K. & Gómez-Serranillos M.P. (2022): Lichen depsidones with biological interest, Planta Medica, 88: 855–880

Depsidones are some of the most abundant secondary metabolites produced by lichens. These compounds have aroused great pharmacological interest due to their activities as antioxidants, antimicrobial, and cytotoxic agents. Hence, this paper aims to provide up-to-date knowledge including an overview of the potential biological interest of lichen depsidones. So far, the most studied depsidones are fumarprotocetraric acid, lobaric acid, norstictic acid, physodic acid, salazinic acid, and stictic acid. … URL EN Read more...

Rositzki M.J., Raksat A., Simmons C.J., Smith C., Choi R.D.V., Wongwiwatthananukit S. & Chang L.C. (2026): A new trichlorinated xanthone and compounds isolated from Cladonia skottsbergii with Antimicrobial properties, Pharmaceuticals, 19(1): 174 [17 p.]

Background/Objectives: The global rise in multidrug-resistant (MDR) bacteria, particularly methicillin-resistant and methicillin-susceptible Staphylococcus aureus (MRSA and MSSA), continues to pose a major public health challenge, including in Hawaii. This underscores the need to discover new antimicrobial agents from natural sources. Guided by teachings from a Buddhist master regarding the medicinal value of lichens, we investigated the endemic Hawaiian lichen Cladonia skottsbergii. Methods: Specimens … URL EN Read more...

Manzitto-Tripp E.A., Watts J.L. & Raynor S.J. (2025): New and noteworthy reports of lichens and allied fungi to Colorado (U.S.A.), including descriptions of two species new to science, Journal of the Botanical Research Institute of Texas, 19(4): 389–418

Colorado’s southern Rocky Mountains and adjacent High Plains are home to some of the most vast, intact, and minimally disturbed natural ecosystems remaining in the western United States. Colorado moreover ranks among the top 10 states in the USA for percentage of land that is in the public domain, and hence a very long history of land conservation, stewardship, and research and interest in natural history. Despite extensive knowledge gained about the biota of Colorado over the prior century, the … URL EN Read more...

Skubała K., Zubek S. & Chowaniec K. (2026): Small-scale spatial heterogeneity of soil chemical and microbiological properties triggered by biocrusts and grasses in sand dunes of temperate climate, Applied Soil Ecology, 217: 106640 [13 p.]

Soils in drylands form a mosaic of vegetated patches and interspaces, creating spatial heterogeneity in soil properties. While plants often generate ‘fertile islands’, interspaces are frequently colonized by biocrusts that also shape soil characteristics. To examine these processes in early successional stages in a sand dune ecosystem, we analyzed microbial activity, soil chemistry, and root colonization by arbuscular mycorrhizal fungi (AMF) and dark septate fungi (DSF) across five compartments: … URL EN Read more...

Rojas-Coll A., Valencia J.-I., Tognarelli J. & Fernández-Bunster G. (2026): Genomic-driven identification of conserved biosynthetic gene clusters in Cladosporium limoniforme: The case of the DHN-melanin pathway, Metabolites, 16(1): 77 [14 p.]

Background: Endolichenic fungi represent an emerging source of bioactive secondary metabolites; however, the genomic basis of their chemical diversity remains largely poorly characterized. Specifically, the metabolic capabilities of Cladosporium limoniforme have not been explored at the genomic level. Objectives: This study aimed to characterize the biosynthetic potential of C. limoniforme by presenting its first whole-genome sequence and conducting a comparative analysis of its biosynthetic gene … URL EN Read more...

Dutra T.S., Nascimento G.M., Santos J.S., Rocha D.D.S. & Cunha-Dias I.P.R. (2025): Expanding the occurrence of Parmotrema enteroxanthum (Parmeliaceae, lichenized Ascomycota) in South America: first record from Brazil, and notes on distribution and conservation assessment, Plant and Fungal Systematics, 70(2): 85–90

Parmotrema enteroxanthum is a restricted distribution foliose lichen, easily recognized by its yellow medulla and salazinic acid content. Previously known only from Venezuela, Colombia, and Bolivia, its distribution in South America remains poorly understood. This study documents the first record of the species in Brazil, with notes on ecology and conservation. Field collections were conducted from Cerrado areas in the state of Maranhão, northeastern Brazil. Morphological and chemical analyses were … URL EN Read more...

Dietrich M. & Liersch S. (2024): Die Digitalisierung des Flechtenherbariums im Bündner Naturmuseum, Jahresbericht der Naturforschenden Gesellschaft Graubünden, 123: 19–30

The digitization of the lichen herbarium of Natural History Museum of the Grisons revealed various interesting results. The majority of the specimens date from the 19 th century, of which the collections of Gottfried Ludwig Theobald and Eduard Wolfgang Killias are particularly significant. Together with the later finds, including those by Josias Braun-Blanquet, they extensively document the canton of the Grisons. In addition to the species Ochrolechia frigida, which is new to Switzerland, several … EN Read more...
