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 … 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 … 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: … 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 … 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 … 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 … Read more...

Ismed F., Arifa N., Zaini E., Bakhtiar A., Umeda D., Putra O.D. & Yonemochi E. (2018): Ethyl haematommate from Stereocaulon graminosum Schaer.: Isolation and crystal structure, Natural Product Sciences, 24(12): 115–118

Herein, we reported the phytochemical investigation of whole thallus Sumatran lichen, Stereocaulon graminosum Schaer., and isolated a mono aromatic compound, ethyl haematommate (1). The structure of compound 1 have been established based on spectroscopic data and confirmed by single crystal X-ray structure analysis. Keywords − Stereocaulon, Lichen, Mono aromatic, Crystal structure. Read more...

Dietrich M. (2015): Gyalecta nidarosiensis auf der Burgruine Nünegg in Lieli (Kanton Luzern) erstmals in der Schweiz nachgewiesen, Herzogia, 28: 798–801

Gyalecta nidarosiensis is reported for the first time for Switzerland. The species, originally described from Norway, requires Atlantic climate conditions and only rarely occurs in Central Europe. The species was observed in the framework of the restoration of the ruins of Nünegg Castle. Key words: Lichenized fungi, new record, conservation, restoration. Read more...

Fernandez-Murillo M.P., Cifuentes E., Beggs A., Manzano M., Gutiérrez-Cortez I., Vargas C., del Río C. & Alfaro F.D. (2026): Assessing the crucial role of marine fog in early soil development and biocrust dynamics in the Atacama Desert, Soil Systems, 10(1):12 [26 p.]

Marine fog is a key non-rainfall water source that sustains microbial activity and transports dissolved nutrients inland, influencing early soil development in hyperarid ecosystems. However, the mechanisms through which sustained fog inputs drive soil surface modification and biocrust formation remain poorly understood. This study evaluated the effects of long-term fog augmentation on soil surface development, biocrust dynamics, and associated microbial communities in the Atacama Desert. We implemented … Read more...

(2026): Mapping the landscape of mycological organizations in Europe: where citizen science meets professional mycology, Biodiversity and Conservation, 35: 37 [26 p.]

Fungi have been used by humans since prehistoric times. Informal structures or groups for knowledge exchange regarding mushrooms and lichens probably existed for ages. Only recently, mycological activities have been structured in formal organizations. And where until a few centuries ago there were only learned societies and naturalists’ clubs, nowadays also mycological societies and citizen scientists have joined the landscape. However, the history of mycological organizations and activities in … Read more...
