Sinigla M., Lőkös L., Varga N., Matus G., Dobronoki D. & Farkas E. (2024): The distribution of Vulpicida pinastri (Parmeliaceae, Lecanorales) in Hungary, Studia Botanica Hungarica, 55: 205–222

Vulpicida pinastri is considered as a vulnerable, rare lichen species in Hungary. According to the old and recent records it prefers humid, boreal-montane habitats of the Northern and the Transdanubian mountain ranges, occurring between 125 and 950 m elevations, growing especially on decaying wood and also on bark of more than 10 host tree species. Hungarian specimens are usually underdeveloped and small sized compared to those living in typical habitats in high mountains. A distribution map together … Read more...

Ren Z., Li R., Wang C., Xue J., Wang L., Wang X. & Zhang L. (2025): Morphology, chemistry, and phylogeny reveal three new species of Lecidea (Lecideaceae) from China, MycoKeys, 121: 341–356

Three new species, Lecidea flavothallia, L. sublaboriosa, and L. tibetica, are reported from China based on morphological, chemical, and molecular characters. Lecidea flavothallia is characterized by an orange thallus and the presence of schizopeltic acid. Lecidea sublaboriosa is characterized by a sparsely developed thallus, brown hypothecium, and the presence of 4-O-demethylplanaic acid in the apothecia. Lecidea tibetica is characterized by a well-developed thallus, I+ violet medulla, hyaline to … Read more...

Zhong C.-J., Zhao Z.-T. & Hu L. (2025): The phylogeny and taxonomy of Violella (Tephromelataceae, lichenized Ascomycota), including a new species from China, MycoKeys, 121: 329–340

Violella yunnanensis C. J. Zhong & L. Hu is described as new to science. It is characterized by its esorediate, areolate to weakly warted thallus, hymenium heavily pigmented with Fucatus-violet pigment, brownish inner ascospore walls, and its chemistry (atranorin and fumarprotocetraric acid). In addition, we collected specimens of Mycoblastus sinensis Kantvilas and Violella wangii T. Sprib. & Goffinet from the holotype localities. Mycoblastus sinensis is transferred to the genus Violella based on … Read more...

Rapaccini G., Porro Z., Passatore L., Trentanovi G., Zoderer B. M., Pirelli P., Guerci L., Galasso G., Quaglini L.A., Cardarelli E., Stefanelli S., Comolli R., Ferré C., Gheza G. & Zacchini M. (2025): Interdisciplinary approach to regenerate contaminated urban sites with novel ecosystems: The multi-layer analysis of La Goccia Forest, a case study in Milan, Forests, 16(9): 1410 [31 p.]

In the face of mounting challenges related to limited availability of urban land and ecological degradation, emerging novel ecosystems offer unique opportunities for ecological regeneration, social redefinition of space, and alternative urban visions. This study presents the multi-layer analysis of the Goccia Forest in Milan (Italy), a wild urban woodland that has developed over sealed and polluted post-industrial land, aiming to investigate the potential of this novel ecosystem to sustain Nature-based … Read more...

Yang M., Hu H., Gao J., Lai Q.W.S., Eshboev F., Leung K.W., Dong T.T., Xu Q. & Tsim K.W.K. (2025): The identification of gyrophoric acid, a phytochemical derived from lichen, as a potent inhibitor for aggregation of amyloid beta peptide: In silico and biochemical evaluation, International Journal of Molecular Sciences, 26(17): 8500 [15 p.]

Alzheimer’s disease (AD) is characterized by amyloid-beta (Aβ) plaque accumulation and neurodegeneration. This study identified gyrophoric acid, a lichen-derived phenolic metabolite, as a dual-action Aβ42 inhibitor preventing aggregation and disassembling of mature Aβ42 fibrils. Integrated in silico studies revealed that gyrophoric acid was a strong thermodynamic stabilizer of Aβ42 (MM–GBSA: −27.3 kcal/mol) via entropically driven hydrophobic interactions and disruption of aggregation-prone … Read more...

Popovici V., Bucur L., Popescu A., Caraiane A. & Badea V. (2018): Determination of the content in usnic acid and polyphenols from the extracts of Usnea barbata L. and the evaluation of their antioxidant activity, Farmacia, 66(2): 337-341

The aim of this study was the identification and quantification of the main active compounds from different Romanian Usnea barbata L. extracts and evaluation of their antioxidant activity. The vegetal product Usneae lichen was harvested from Călimani Mountains, Suceava County, Romania, in March 2016. We prepared 10% extracts in: acetone, 96% ethanol and water. The quantitative analysis of the identified constituents was performed using an HPLC method. The antioxidant activity was evaluated by the … Read more...

Boudreault C., P. Drapeau, M. Bouchard, M.-H. St-Laurent, L. Imbeau & Y. Bergeron (2015): Contrasting responses of epiphytic and terricolous lichens to variations in forest characteristics in northern boreal ecosystems, Canadian Journal of Forest Research, 45(5): 595-606

The main environmental factors that drive lichen communities are still poorly known in northern boreal ecosystems. This study compares the effects of forest stand characteristics (height, canopy cover, and age) on fruticose epiphytic and terricolous lichen communities across a large region located at the interface between closed-crown boreal forests and northern open woodlands in the province of Quebec (Canada). The dataset consists of 875 plots spread across a 242 000km2 territory that ranges from … Read more...

de Albuquerque M.P., Putzke J., Schünemann A.L., Vieira F.C.B., Victoria F.D.C. & Pereira A.B. (2018): Colonisation of stranded whale bones by lichens and mosses at Hennequin Point, King George Island, Antarctica, Polar Record, 54(1): 29-35

This paper presents the details of lichens and mosses found on whale vertebrae substratum in the Admiralty Bay area, King George Island, Antarctica. Samples were taken in the coastal area at Hennequin Point, a relict of the Antarctic whaling era. The samples were collected from the upper surface of the whale bones found in the study area during the austral summer 2010–2011. A total of 15 lichen and two moss species were found. All species sampled are known in the Admiralty Bay area, both as pioneers … Read more...

Boguslavsky A., Yurkevich N., Saeva O. & Gaskova O. (2017): Biosorption of uranyl ion from radioactive solution, International Multidisciplinary Scientific GeoConference Surveying Geology and Mining Ecology Management, SGEM, 17(52): 113-120

U(VI) biosorption by six natural materials: three types of peats, Polytrichium moss, Eichhórnia crássipes water plant and Cladonia stellaris lichen was investigated. Natural sorbents were selected, as it is available, cheap and accessible materials. The effects of initial concentration of UO2 2- in the model radioactive solution and pH on the sorption uranyl ions were assessed. Adsorption isotherms and constants for given adsorbates and adsorbents were determined. Equilibrium is well described … Read more...
