Xue X.-D., Jiang S.-H. & Ren Q. (2023): Fouragea gyrophorica sp. nov. from China, with morphological and phylogenetic evidence - Bryologist, 126(2): 167–173

A new species Fouragea gyrophorica is described from China. It is most similar to F. vegae, but differs by its sparsely to densely branched apothecia, and it often has an obvious prothallus, and the presence of gyrophoric acid detected by TLC. This is the first report that Fouragea contains lichen substances. An analysis of its relationships based on molecular phylogeny is given. A world key to the species of Fouragea is also presented. Key words: Lichenized fungi, taxonomy, Opegraphaceae, foliicolous. Read more...

de Lange P.J., Blanchon D.J., Marshall A.J. & Schmid L.M.H. (2023): Lepra erythrella (Pertusariaceae) – a new addition to the lichenized mycobiota of the Aotearoa / New Zealand archipelago - Український ботанічний журнал [Ukrainian Botanical Journal], 80(1): 94–97

An investigation of the fl ora, mycobiota and lichenized mycobiota associated with the endemic Aotearoa / New Zealand plant genus Lophomyrtus (Myrtaceae) revealed a specimen of Lepra erythrella (Pertusariaceae). Lepra erythrella, though briefl y mentioned in a paper documenting the results of that Lophomyrtus study, has not yet been formally admitted into the lichenized mycobiota of Aotearoa / New Zealand. Th erefore, to complete that process in this paper, we provide a description based … Read more...

Sellers H.L., Vargas Zesati S.A., Elmendorf S.C., Locher A., Oberbauer S.F., Tweedie C.E., Witharana C. & Hollister R.D. (2023): Can plot-level photographs accurately estimate tundra vegetation cover in northern Alaska? - Remote Sensing, 15(8): 1972 [24 p.]

Plot-level photography is an attractive time-saving alternative to field measurements for vegetation monitoring. However, widespread adoption of this technique relies on efficient workflows for post-processing images and the accuracy of the resulting products. Here, we estimated relative vegetation cover using both traditional field sampling methods (point frame) and semi-automated classification of photographs (plot-level photography) across thirty 1 m2 plots near Utqiaġvik, Alaska, from 2012 to … Read more...

Filimonov A., Luzina O., Gatilov Y. & Salakhutdinov N. (2023): Regioselectivity amination of usnic acid by ammonia in water - Molbank, 2023(2): M1618 [6 p.]

Usnic acid is a well-known secondary lichen metabolite exhibiting a broad spectrum of biological activity. Previously it was shown that the reaction of usnic acid with various amines resulted in enamine-bond formation instead of the C(11)=O carbonyl group. Enamines obtained have a pronounced biological activity. In this work, we have shown that the reaction of usnic acid with ammonia can be regioselective if the solvent is replaced by water. The regioselectivity of that reaction depends on temperature … Read more...

Bednaříková M., Gauslaa Y. & Solhaug K.A. (2023): Non-invasive monitoring of photosynthetic activity and water content in forest lichens by spectral reflectance data and RGB colors from photographs - Fungal Ecology, 62: 101224 [8 p.]

There is a need for non-invasive monitoring of temporal and spatial variation in hydration and photosynthetic activity of red-listed poikilohydric autotrophs. Here, we simultaneously recorded kinetics in RGB-colors (photos), reflectance spectra, water content, maximal (FV/FM), and effective quantum yield of PSII (ΦPSII) during desiccation in foliose lichens differing in cortical characteristics and photobionts. The spectral absorbance peaks of chlorophyll a, phycocyanin, and phycoerythrin were clearly … Read more...

Vandinther N. & Aherne J. (2023): Biodiversity-based empirical critical loads of nitrogen deposition in the Athabasca Oil Sands Region - Nitrogen, 4(2): 169–193

Anthropogenic nitrogen (N) emissions can have considerable effects on terrestrial ecosystems, with chronic N deposition leading to changes in plant species composition. The Athabasca Oil Sands Region (AOSR) represents a large point source of N emissions, which has prompted concern for surrounding habitats. The objective of this study was to determine the relative importance of N deposition as a driver of plant species community composition against bioclimatic and soil chemical variables. Further, … Read more...

García R. (2023): La funga liquenizada de la Reserva “Eco Área de Avellaneda” y su relación con otras áreas protegidas del Río de la Plata - Historia Natural (tercera serie), 12(3): 169–180

[in Spanish with English abstract: ] On the southern bank of the Río de la Plata there is a forest ecosystem that has suffered the ravages of urbanization, which is known as jungle or gallery forest. Within this ecosystem there is a recently formed natural reserve: the Municipal Reserve “Eco Area of Avellaneda”, which is surrounded by one of the most populated areas in the country. Epiphytic lichen species were surveyed. A total of 43 species were found. Comparisons were made by means … Read more...

Nguyen N.-H., Nguyen P.-T., Otake H., Nagata A., Hirano N., Imanishi-Shimizu Y. & Shimizu K. (2023): Biodiversity of basidiomycetous yeasts associated with Cladonia rei lichen in Japan, with a description of Microsporomyces cladoniophilus sp. nov. - Journal of Fungi, 9(4): 473 [16 p.]

For more than a century, lichens have been used as an example of dual-partner symbiosis. Recently, this has been challenged by the discovery of various basidiomycetous yeasts that coexist in multiple lichen species, among which Cladonia lichens from Europe and the United States were discovered to be highly specifically associated with the basidiomycetous yeast of the family Microsporomycetaceae. To verify this highly specific relationship, we investigated the diversity of basidiomycetous yeasts associated … Read more...

Yang Q., Song Z., Li X., Hou Y., Xu T. & Wu S. (2023): Lichen-derived Actinomycetota: Novel taxa and bioactive metabolites - International Journal of Molecular Sciences, 24(8): 7341 [22 p.]

Actinomycetes are essential sources of numerous bioactive secondary metabolites with diverse chemical and bioactive properties. Lichen ecosystems have piqued the interest of the research community due to their distinct characteristics. Lichen is a symbiont of fungi and algae or cyanobacteria. This review focuses on the novel taxa and diverse bioactive secondary metabolites identified between 1995 and 2022 from cultivable actinomycetota associated with lichens. A total of 25 novel actinomycetota species … Read more...

Chahloul N., Khadhri A., Vannini A., Mendili M., Rayes A. & Loppi S. (2023): Selecting the species to be used in lichen transplant surveys of air pollution in Tunisia - Environmental Monitoring and Assessment, 195: 570 [8 p.]

This study was undertaken with the aim of selecting one or more lichen species that are the most suitable for transplant-based surveys of air pollution in Tunisia, in areas where the local native lichen vegetation is scanty or missing at all. To this purpose, four epiphytic (tree inhabiting) lichen species (Evernia prunastri, Flavoparmelia caperata, Parmotrema perlatum, Ramalina farinacea) were collected from the Babouch forests, a remote and unpolluted area of NW Tunisia, and analyzed for their … Read more...
