Sankar K., Selvi M.C., Kumar R.S., Karuppiah P., Periyasami G., Karthikeyan P. & Tamil Selvan E.B. (2025): Effectiveness of image-based classifiers for on-site identification of lichens in reserved forest, Computers and Electronics in Agriculture, 239: 110994 [22 p.]

The collection and identification of lichen samples within the reserved forest pose significant challenges, leading researchers to seek alternative methodologies. Manual identification of lichens requires microscopic and chemical analysis, which is time-consuming and requires domain expert knowledge. Deep learning models can automatically learn complex lichen features from images, thereby avoiding manual feature extraction. In this context, an in-depth study was conducted using two approaches to … Read more...

Dahlberg A., Pioli S., Jönsson M., Barbi F., Thor G. & Tuovinen Nogerius V. (2025): Detailed analysis of fungal communities in Norway spruce logs reveals stochastic fine-scale patterns of species and detects lichen forming fungi without their photobionts, Fungal Ecology, 78: 101458 [13 p.]

Fungal ecologists have long been intrigued by the mechanisms behind the high fungal species richness in dead wood at small and large spatial scales. We identified processes resulting in fine-scale fungal community patterns with a network analysis based on a detailed metabarcode mapping of fungi in and on the surfaces of eight naturally fallen Norway spruce logs in northern Sweden. Our results show that (1) dominant species and communities of fungi vary significantly among the logs, (2) wood inside … Read more...

Bişgin D., Halıcı M.G. & Yiğit M. (2025): DNA barcoding of some lichenized fungi from Dismal Island, Biological Diversity and Conservation, 18(3): 372–388

Lichenized fungi are the most dominant macro organisms in Antarctic terrestrial ecosystems. Studies on lichens in Antarctica have a history of approximately two centuries. Especially with the recent use of DNA-based techniques in taxonomy studies, lichen biodiversity studies in Antarctica has accelerated. Dismal Island is the largest of the Faure Islands, 1.9 kilometers long and 60 meters high, mostly covered with ice in Marguerite Bay on the west coast of Graham Land. In the literature, there is … Read more...

Kubiak D. & Sucharzewska E. (2025): Nieustający czar „skali porostowej” [The enduring charm of the “lichen scale”], Wiadomości Botaniczne, 69: 202952 [7 p.]

The paper discusses the history of the Hawksworth-Rose lichen scale (1970), which played a very important role in the development of bioindication studies and monitoring of atmospheric pollution in Europe. This scale was created to assess air pollution with sulfur dioxide in the period when its concentrations reached unprecedented values today. Due to the significant improvement in air quality and a clear decrease in SO2 concentrations in recent years (below the lower threshold of lichen sensitivity … Read more...

(2025): Materiały do rozmieszczenia porostów i grzybów naporostowych Polski, 5 [Materials for the distribution of lichens and lichenicolous fungi in Poland, 5], Wiadomości Botaniczne, 69: 204055 [22 p.]

The paper presents new localities of 38 species of lichens and 7 species of lichenicolous fungi (marked by an asterisk), endangered in the country or considered regionally rare. Several of the recorded taxa (Acrocordia cavata, Catinaria neuschildii, Gyalidea minuta, Knufia peltigerae, Paranectria oropensis, Stigmidium rivulorum and Trichonectria anisospore) were previously known from single localities in Poland. The name of each taxon is followed by data on its diagnostic features and distribution … Read more...

Zibold M., Weckesser M. & Scholler M. (2025): Epiphytic lichens in old castle parks in Southwest Germany: A case study, Urban Ecosystems, 28: 203 [11 p.]

Old cultural landscapes, such as old parks and gardens, can be expected to be rich lichen habitats, as they offer otherwise rare microstructures and a high habitat continuity. Yet, old parks are not well studied with regard to their lichen flora. In this study, we investigated three old castle parks in southwest Germany and recorded the epiphytic (bark-inhabiting) lichen flora on 205 native and non-native trees, belonging to 63 tree species. We surveyed lichens on tree stems and assessed tree diameter, … Read more...

(2016): Flavoparmelia caperata, a host for Beauveria sp. in subalpine forest of Chakrata district, Uttarakhand, India, and natural selection in B. bassiana, Asian Journal of Microbiology, Biotechnology and Environmental Sciences, 18(4): 983-990

Lichen thallus, composed of photobiont, mycobiont and often other fungi and bacteria, can be considered as mini-ecosystem comprising several organisms. The present study was focused on the isolation and identification of the fungusassociated with the corticolous lichen Flavoparmelia caperata collected from subalpine forest of Cedar (Cedrusdeodara (Roxb.) G. Don) in Chakrata district, Uttarakhand, India; comparison of secondary metabolites produced from the isolated fungus and the lichen thallus via … Read more...

Savković Ž., Unković N., Stupar M., Franković M., Jovanović M., Erić S., Šarić K., Stanković S., Dimkić I., Vukojević J. & Ljaljević Grbić M. (2016): Diversity and biodeteriorative potential of fungal dwellers on ancient stone stela, International Biodeterioration & Biodegradation, 115: 212-223

Biodeterioration caused by fungal colonizers on an ancient stone stela, excavated from the former Roman settlement (Eastern Serbia) was investigated. According to selected biodeterioration elements, average deterioration index was assessed (0.8), prompting the need for conservation. Fungal somatic and reproductive structures, along with lichen thalli and moss fragments, were detected on the surface using different microscopy and cultivation methods. In situ microscopy on the site was implemented, … Read more...

Schmitz D., Putzke J., de Albuquerque M.P., Schünemann A.L., Vieira F.C.B., Victoria F.D.C. & Pereira A.B. (2018): Description of plant communities on Half Moon Island, Antarctica, Polar Research, 37(1): 1523663

During February–March of the austral summers of 2013/14 and 2014/2015, fieldwork was performed on Half Moon Island, South Shetland Archipelago, Antarctica, to evaluate the distribution and abundance of mosses and lichens, as well as to describe and map the plant communities there. The quadrat (20 × 20 cm) sampling method was employed in a phytosociological study that aimed to describe these communities. The area was mapped using an Astech Promark II® DGPS, yielding sub-metric precision after … Read more...

Adhikari R., Pal N., Nayaka S. & Prakash P. (2025): New species and nomenclatural updates in Graphidaceae from Western Himalaya, India, Bryologist, 128(3): 551–555

Three new species of Graphidaceae, Allographa binsarensis, Graphis albothallina, and G. moriensis, are described as new to science from the Western Himalayan part of India. Allographa binsarensis differs from the closely related A. semirigida in having short, mostly unbranched lirellae with lateral thalline margins; G. albothallina differs from G. appendiculata in having much prominent lirellae with distinctly striate labia and white lineages along the striae; while G. moriensis differs from G. astrolirellata … Read more...
