Arup U., Malíček J., Schiefelbein U. & Holien H. (2025): Lecanora hybocarpa and similar European species, Lichenologist, 57: 239–255

The lichen genus Lecanora is one of the largest genera of lichenized fungi. The core part of the genus is the L. subfusca group and within this group, Lecanora hybocarpa (Tuck.) Brodo, initially described from North America and thought to be endemic, has been reported from several European countries. However, the identity of these European specimens has been increasingly questioned. This study aimed to clarify the relationship between North American L. hybocarpa and European collections, including … Read more...

Fryday A.M., Ruprecht U., Götz A & Kantvilas G. (2025): Aurantiothallia and Hertelaria, two new genera of porpidioid Lecideaceae (Ascomycota, Lecanoromycetidae, Lecideales), and other new porpidioid taxa from Tasmania, Lichenologist, 57: 256–277

The new genera Aurantiothallia and Hertelaria are proposed for species of saxicolous lichens known only from Tasmania. Aurantiothallia is erected for the species currently known as Poeltiaria tasmanica and the newly described A. riparia, both of which have an orange thallus lacking lichen products but with an amyloid medulla and black apothecia with only brown pigments internally. Hertelaria is based on the new species H. doleritica, which has an atrobrunnea-type thallus and large adnate, red-brown … Read more...

Ivanovich-Hichins C., Weber L., Li L., Leavitt S.D., Muggia L., Palice Z., Pérez-Ortega S., Sohrabi M. & Printzen C. (2025): New phylogenetic insights into the lichen genus Lecanora s. lat. (Lecanoraceae, Ascomycota): resurrection of the genera Glaucomaria, Straminella and Zeora, Lichenologist, 57: 278–303

A new phylogenetic analysis of Lecanora s. lat. is presented based on a dataset of seven loci, including recently published mitochondrial markers. In this analysis, comprising 136 specimens and 572 sequences, several clades that can be circumscribed taxonomically are recovered as monophyletic with strong support. Lecanora divides into two large monophyletic subclades. The well-supported MPRPS clade sensu Medeiros et al. (2021) combines the genera Lecanoropsis, Myriolecis, Protoparmeliopsis, Rhizoplaca … Read more...

Vtípilová V., Timdal E., Stodůlková E., Semerád J., Resl P. & Steinová J. (2025): Cladonia rubrotincta, a new species distinct from C. norvegica, Lichenologist, 57: 304–316

Cladonia norvegica was originally described from Norway based on different morphological and chemical characters distinguishing the species from C. coniocraea. Shortly after its description, material containing red spots on the thallus was reported from different parts of the world, but the taxonomic status of this form remained unclear. In this study, we investigated the morphological, chemical and genetic differences between the spotless form of C. norvegica and the red-spotted material. Phylogenetic … Read more...

Ísleifsdóttir D., Xu M., Biwersi M., Leblanc M.-J., Heiðmarsson S., Pálsson S., Sorensen J.L., Viktorsson E.Ö. & Ólafsdóttir E.S. (2026): Is the reindeer lichen Cladonia arbuscula really producing isousnic acid? A chemotaxonomy query, Molecules, 31(1): 143 [10 p.]

Isousnic acid (isoUA) has been detected in a few usnic acid (UA)-producing lichens with chemotaxonomic values. IsoUA was first isolated from a specimen belonging to Cladonia arbuscula s.l. (referred to as C. mitis in the publication). However, the isolation and detection of isoUA in this Cladonia species have not been reproduced and confirmed with clear evidence. This study focused on C. arbuscula s.l. collected in Iceland and aimed to (1) identify the lichen specimen using DNA barcoding and (2) … Read more...

Obermayer W. (2025): Dupla Graecensia Lichenum (numbers 1451–1500), Fritschiana (Graz), 103: 1–17

The exsiccata 'Dupla Graecensia Lichenum (numbers 1451–1500)' comprises 50 collections (767 specimens) of lichen duplicates from the following 12 countries [the number of taxa is given in square brackets]: Albania (district of Nat [1]), Austria (states of Carinthia [2], Salzburg [3], Styria [12], Tyrol [3], and Upper Austria [10]), Cameroon [2], Canada (pro-vinces of British Columbia [1] and Quebec [1]), France (region Auvergne-Rhône-Alpes [1]), Greece (region of Central Mazedonia [1], islands … Read more...

Gavarró P., Bros V., Sáez L., Santos X., Real J., Pons D. & Puig-Gironès R. (2026): Evaluating biotic interactions in a hard and fragile ecosystem: xerophilous land snails and epilithic cryptogram communities in rocky outcrops, Acta Oecologica, 130: 104153 [10 p.]

In biodiversity hotspots like rocky outcrops, species distribution is shaped by environmental factors at multiple scales, with microhabitat characteristics like substrate composition and shelter playing key roles. These fragile ecosystems host a rich diversity of species, including endemic and endangered taxa. However, they remain underexplored in conservation research, despite their crucial role in sustaining xerophilic biodiversity. This study investigates the environmental drivers of xerophilous … Read more...

Pino-Bodas R., Ahti T., Stenroos S. & Sanmartín I. (2026): Diversification and spatio-temporal evolution of Cladoniaceae (Lecanorales, Ascomycota), a widespread family of lichen-forming fungi, Fungal Biology, 130(1): 101710 [18 p.]

The lichen-forming fungi family Cladoniaceae has a great ecological relevance and forms the most important group of terricolous lichens. They make up a significant element of the vegetation of numerous biomes, such as boreal forests, the tundras, and the páramos of South America. Within Cladoniaceae, Cladonia is the most diverse genus, distributed in all continents. Here, we explore the role played by dispersal and ecological opportunity in the diversification and geographic expansion of Cladonia … Read more...

Cuellar M.A., Mejía J., Quintero-Pertuz H., Castro-Álvarez A., Mellado M., Vera-Quezada W., Montenegro G., Espinosa-Bustos C., Bridi R. & Salas C.O. (2026): Experimental and In Silico Studies to Unravel the Antioxidant and Antibacterial Properties of Lichen Metabolites from Pseudocyphellaria compar and Pseudocyphellaria nudata, Antioxidants, 15(1): 34 [21 p.]

Lichens are a source of diverse compounds with a wide range of biological activities, making them of significant interest for novel drug development. In this study, metabolites were extracted from Lobariaceae lichens, and their antioxidant and antibacterial properties were experimentally investigated and explained using various computational approaches. Specifically, four lichen metabolites were analyzed using three methods to assess their antioxidant capacity. Antibacterial activity assays were … Read more...
