Bui V.M., Huynh B.L.C., Pham N.K.T., Nguyen T.A.T., Nguyen T.T.T., Nguyen K.P.P. & Nguyen T.P. (2022): Usneaceratins A and B, two new secondary metabolites from the lichen Usnea ceratina - Natural Product Research, 36(15): 3945–3950

Two new compounds, comprising one dibenzofuran, named usneaceratin A (1), and one phenolic acid, named usneaceratin B (2), together with one known dibenzofuran, isousnic acid (3), and two known phenolics, orsellinic acid (4) and methyl orsellinate (5) were clarified from the lichen Usnea ceratina using variously chromatographic methods. Their structures were testified by comprehensive HR-ESI-MS, and NMR spectroscopic analysis, and comparison with published data. Their α-glucosidase inhibitory activity … Read more...

Mendili M., Seaward M.R.D. & Khadhri A. (2022): Does the lichenicolous fungus Heterocephalacria bachmannii affect the antimicrobial potential of its host Cladonia foliacea? - Natural Product Research, 36(12): 3095–3099

The effects of the lichenicolous fungus Heterocephalacria bachmannii on the antimicrobial potential of the lichen Cladonia foliacea demonstrated that the extracts investigated have antimicrobial potential against gram-positive and negative bacteria, and yeast, and inhibit the germination of fungal spores. Inhibition activity varied considerably depending on the extract, the bacterial species, and the absence or presence of H. bachmannii; unparasitised C. foliacea has a higher antimicrobial activity. … Read more...

Susithra E., Meena R., Chamundeeswari D., Rajasekhar C., Naveena Lavanya Latha J. & Basaveswara Rao M.V. (2022): Low molecular weight non-peptidyl antimalarial leads: Lichen metabolite, usnic acid and its analogues - Polycyclic Aromatic Compounds, 42(8): 5020–5028

The search for newer antimicrobial agents is a developing and continuing process. With an aim to discover new antimalarial leads from natural sources, a unique lichen-derived metabolite namely, usnic acid (USA) and their analogues were screened against a chloroquine-sensitive Plasmodium falciparum 3D7 line using an in vitro parasite growth inhibition assay. A bio guided fractionation of USA, the molecule of interest, derived from the ether extract of the lichen, Usnea undulata, reported to … Read more...

Errington R.C., Macdonald S.E., Melnycky N.A. & Bhatti J.S. (2022): Estimating lichen biomass in forests and peatlands of northwestern Canada in a changing climate - Arctic, Antarctic, and Alpine Research, 54(1): 221–238

Climate warming in the North could lead to lichen decline within critical woodland caribou habitat. We used repeat measurements of sixty-nine plots over ten years (2007–2008 and 2017–2018) to assess lichen biomass changes under a warming climate along a latitudinal/climatic gradient in northwestern Canada. We compared lichen biomass on sensitive landscape features, including peat plateaux (permafrost-containing bogs), areas of permafrost thaw within the peat plateaux (collapse scars), and … Read more...

Gheza G., Di Nuzzo L., Nimis P.L., Benesperi R., Giordani P., Vallese C. & Nascimbene J. (2022): Towards a Red List of the terricolous lichens of Italy - Plant Biosystems, 156(3): 824–825

Terricolous lichens, threatened in many areas of Europe, have been greatly overlooked in conservation policies. This work provides a provisional Red List of the terricolous lichens of Italy, to favour their inclusion in conservation policies. The taxa were assigned to IUCN categories according to a simplified assessment procedure based on their rarity and past/current distribution in the administrative regions and ecoregions of Italy. We evaluated 162 species: 30 were listed as regionally extinct, … Read more...

Frati L., Brunialti G., Landi S., Filigheddu R. & Bagella S. (2022): Exploring the biodiversity of key groups in coppice forests (Central Italy): the relationship among vascular plants, epiphytic lichens, and wood-decaying fungi - Plant Biosystems, 156(4): 835–846

Sustainable Forest Management (SFM) indicators consider the main ecological and socioeconomic functions of forests but do not currently include some key groups widely adopted to assess the effects of forest management, such as herbaceous vascular plants, epiphytic lichens, and wood-decay fungi. Moreover, they are shaped into high forests while in the Mediterranean area the oldest type of forest management is coppice. We investigated the diversity and the relationships of the above-mentioned … Read more...

Soto Medina E., Aptroot A. & Lücking R. (2022): New records of lichen genera and species for Colombia - Revista de la Academia Colombiana de Ciencias Exactas, Físicas y Naturales, 46(180): 751–757

Dirina paradoxa, Heterocyphelium triseptatum, Julella sublactea, Opegrapha aurantiaca, Peltula steppae, Sarcographina cyclospora and Schistophoron tenue are reported for the first time in Colombia. The genera Dirina, Heterocyphelium Sarcographina and Schistophoron are reported for the first time in Colombia. These lichens mainly originate from dry ecosystems where previous collections of lichenized fungi have been uncommon. Key words: crustose lichens; tropic; taxonomy. Read more...

[Ismailov A.B.] (2022): Анализ разнообразия и функциональных признаков эпифитных лишайников в лесах Дагестана разных формаций [Analysis of diversity and functional traits of epiphytic lichens in Dagestan forests of different formations] - Юг России: экология, развитие [South of Russia: ecology, development], 17(3): 125–134

[in Russian with English abstract: ] Aim. The structure of forest communities changes along the altitude gradient, which determines the composition of epiphytic lichens. The aim of the study is to compare the species composition and functional characteristics of epiphytic lichens in Dagestan forests of different formations to identify key differences in the lichen flora. Material and Methods. Data on diversity and structure of 334 species of epiphytic lichens … Read more...

Lumbsch H.T. & Türk R. (2022): Varicellaria velata occurs in the Alps - Herzogia, 35(1): 74–76

Varicellaria velata in its current circumscription has a worldwide distribution and is common in tropical and subtropical habitats but also extends into the temperate zone. In Europe it has a subatlantic distribution and has also been recorded from a single locality in Austria for the Alps. This record has recently been interpreted as dubious and consequently, the species was not listed in recent checklists of the Alps and Austria. We here report a new collection of this species from Austria … Read more...
