Diaz V. & Manzitto-Tripp E. (2023): A synopsis of the yellow-green, usnic acid-producing, species of Xanthoparmelia in Colorado - Opuscula Philolichenum, 22: 1-40

The genus Xanthoparmelia belongs to one of the largest and most species-rich foliose lichen families - Parmeliaceae. It occurs primarily in arid regions around the world. In the United States, Xanthoparmelia is extremely abundant in the southern Rocky Mountains and adjacent high plains of Colorado, where species play significant ecological roles. The present study emphasizes the examination of type material, protologues, study of new field collections as well as existing herbarium material, data … URL EndNote PDF Read more...

Llewellyn T., Nowell R., Aptroot A., Temina M., Prescott T., Barraclough T. & Gaya E. (2023): Metagenomics Shines Light on the Evolution of "Sunscreen" Pigment Metabolism in the Teloschistales (Lichen-Forming Ascomycota) - Genome Biology and Evolution, 15(2): 1-19

Fungi produce a vast number of secondary metabolites that shape their interactions with other organisms and the environment. Characterizing the genes underpinning metabolite synthesis is therefore key to understanding fungal evolution and adaptation. Lichenized fungi represent almost one-third of Ascomycota diversity and boast impressive secondary metabolites repertoires. However, most lichen biosynthetic genes have not been linked to their metabolite products. Here we used metagenomic sequencing … URL EndNote PDF Read more...

Westberg M., Hammarström O., Isaksson R., Johansson P., Thor G., Vicente R. & Svensson M. (2023): Additions to the flora of lichenicolous fungi of Sweden - Graphis Scripta, 35(1): 4-13

15 lichenicolous fungi are reported as new to Sweden: Abrothallus halei, A. puntilloi, Arthonia japewiae, A. parietinaria, Buelliella lecanorae, Lecidella parasitica, Opegrapha lamyi, O. pertusariicola, Parmeliicida pandemica, Rosellinula frustulosae, Sclerococcum microsporum, Stigmidium acetabuli, S. hageniae, S. humidum and Xenonectriella physciacearum. Eight of these are also new to Fennoscandia. URL EndNote PDF Read more...

Erlandsson R., Arneberg M.K., Tømmervik H., Finne E.A., Nilsen L. & Bjerke J.W. (2023): Feasibility of active handheld NDVI sensors for monitoring lichen ground cover - Fungal Ecology, 63: 101233 [9 p.]

Vegetation indices are corner stones in vegetation monitoring. However, previous field studies on lichens and NDVI have been based on passive sensors. Active handheld sensors, with their own light sources, enables high-precision monitoring under variable ambient conditions. We investigated the use of handheld sensor NDVI for monitoring pale lichen cover across three study sites from boreal heathlands to High Arctic tundra (62–79 °N), and compared it with Sentinel-2 satellite NDVI. NDVI decreased … URL EndNote Read more...

Khakhar A. (2023): A roadmap for the creation of synthetic lichen - Biochemical and Biophysical Research Communications , 654: 87–93

Lichens represent a charismatic corner of biology that has a rich history of scientific exploration, but to which modern biological techniques have been sparsely applied. This has limited our understanding of phenomena unique to lichen, such as the emergent development of physically coupled microbial consortia or distributed metabolisms. The experimental intractability of natural lichens has prevented studies of the mechanistic underpinnings of their biology. Creating synthetic lichen from experimentally … URL EndNote Read more...

Hekkala A.-M., Jönsson M., Kärvemo S., Strengbom J. & Sjögren J. (2023): Habitat heterogeneity is a good predictor of boreal forest biodiversity - Ecological Indicators, 148: 110069 [14 p.]

Reliable assessment measures are crucial for tracking changes in biodiversity and for evaluating the state of biodiversity. Two of the main drivers of biodiversity are habitat heterogeneity and resource amount. These drivers are used as proxies of biodiversity but assessing both is costly, limiting their practical use. To test which of the drivers best predicts the number and abundance of sessile species of conservation concern (including macrofungi, lichens, bryophytes, and vascular plants), … URL EndNote PDF Read more...

(2023): Mycobiont-specific primers facilitate the amplification of mitochondrial small subunit ribosomal DNA: a focus on the lichenized fungal genus Melanelia (Ascomycota, Parmeliaceae) in Iceland - MycoKeys, 96: 57–75

The fungal mitochondrial small subunit (mtSSU) ribosomal DNA is one of the most commonly used loci for phylogenetic analysis of lichen-forming fungi, but their primer specificity to mycobionts has not been evaluated. The current study aimed to design mycobiont-specific mtSSU primers and highlights their utility with an example from the saxicolous lichen-forming fungal genus Melanelia Essl. in Iceland. The study found a 12.5% success rate (3 out of 24 specimens with good-quality mycobiont mtSSU sequences) … URL EndNote Read more...

Boonpeng C., Sangiamdee D., Noikrad S. & Boonpragob K. (2023): Assessing seasonal concentrations of airborne potentially toxic elements in tropical mountain areas in Thailand using the transplanted lichen Parmotrema tinctorum (Despr. ex Nyl.) Hale - Forests, 14(3): 611 [19 p.]

The atmosphere of mountain areas may be contaminated by pollutants originating mainly from road traffic, as well as tourist and community activities within such areas. This study mainly aimed to assess the concentrations of airborne potentially toxic elements (PTEs) in two mountain areas in Thailand using lichen biomonitoring. Thalli of the lichen Parmotrema tinctorum from the relatively unpolluted area in Khao Yai National Park (KYNP) were prepared and exposed at nine sites in the KYNP and nine … URL EndNote PDF Read more...

Nascimbene J., Nimis P.L., Klüßendorf J. & Thüs H. (2023): Freshwater lichens, including new species in the genera Verrucaria, Placopyrenium and Circinaria, associated with Lobothallia hydrocharis (Poelt & Nimis) Sohrabi & Nimis from watercourses of Sardinia - Journal of Fungi, 9(3): 380 [25 p.]

This work summarizes the results of the exploration of freshwater lichen biota on the island of Sardinia associated with the regional flagship species Lobothallia hydrocharis, a large-sized crustose lichen from the splash zone along mountain streams, so far known from Sardinia only. Molecular data were used to confirm its distinctiveness from other taxa and its systematic placement and to identify critical taxa among its associated lichen biota. We found 25 species of lichenized fungi, including … URL EndNote Read more...
