(2022): Large differences in carbohydrate degradation and transport potential among lichen fungal symbionts - Nature Communications, 13: 2634 [13 p.]

Lichen symbioses are thought to be stabilized by the transfer of fixed carbon from a photosynthesizing symbiont to a fungus. In other fungal symbioses, carbohydrate subsidies correlate with reductions in plant cell wall-degrading enzymes, but whether this is true of lichen fungal symbionts (LFSs) is unknown. Here, we predict genes encoding carbohydrate-active enzymes (CAZymes) and sugar transporters in 46 genomes from the Lecanoromycetes, the largest extant clade of LFSs. All LFSs possess a robust … Read more...

Yang M.X., Wang L.S., Miao C.C. & Scheidegger C. (2022): From cradle to grave? A global hotspot and new species of the genus Lobaria discovered in the Himalayas and the Hengduan Mountains - Persoonia, 48: 150–174

n this study, the East Asian diversity of green-algal Lobaria was evaluated by applying both morphological and phylogenetic approaches. A multi-locus phylogenetic analysis of 72 green-algal Lobaria specimens was performed using a three-locus and time-calibrated species-tree approach. The analyses demonstrate that pairs of sexually and vegetatively reproducing lineages split into highly supported monophyletic clades. Taxonomically, 11 green-algal Lobaria species were identified as new to science, … Read more...

Zakeri Z., Junne S., Jäger F., Dostert M., Otte V. & Neubauer P. (2022): Lichen cell factories: methods for the isolation of photobiont and mycobiont partners for defned pure and co-cultivation - Microbial Cell Factories, 21: 80 [11 p.]

Background: Due to their huge biodiversity and the capability to produce a wide range of secondary metabolites, lichens have a great potential in biotechnological applications. They have, however, hardly been used as cell factories to date, as it is considered to be difcult and laborious to cultivate lichen partners in pure or co-culture in the laboratory. The various methods used to isolate lichen fungi, based on either the ascospores, the conidia, or the thallus, have so far not been compared … Read more...

Yazici K., Aslan A. & Etayo J. (2022): Lichens and lichenicolous fungi from the Bingol Province in Turkey - Phytologia Balcanica, 28(1): 11–38

This study is a contribution to the Lichen Biota of Turkey. As a result of the examination of lichens and lichenicolous fungi from 169 stations, 341 lichens and 23 lichenicolous fungi have been identified. While Sphaerellothecium contextum, a lichenicolous fungus, is new to Turkey, 19 lichenized and three lichenicolous fungi were found for the second time in Turkey. Key words: Ascomycota, Bingöl, biodiversity, lichen, Turkey. Read more...

Roser L.A., Erkoc P., Ingelfinger R., Henke M., Ulshöfer T., Schneider A.-K., Laux V., Geisslinger G., Schmitt I., Fürst R. & Schiffmann S. (2022): Lecanoric acid mediates anti-proliferative effects by an M phase arrest in colon cancer cells - Biomedicine & Pharmacotherapy, 148: 112734 [9 p.]

Lichen extracts containing, among other compounds, depsides such as evernic acid, atranorin, and lecanoric acid possess anti-proliferative effects. We aimed to identify lichen metabolites that are responsible for the observed anti-proliferative effects. We performed cytotoxicity, cell colony, cell cycle and apoptosis assays in various cell lines or primary immune cells. We analyzed several cell cycle proteins and apoptosis-related proteins to gain insights into the underlying mechanism. All … Read more...

Mollier S., Kunstler G., Dupouey J.-L. & Bergès L. (2022): Historical landscape matters for threatened species in French mountain forests - Biological Conservation, 269: 109544 [19 p.]

Ancient forests are known to host a biodiversity of high ecological distinctiveness and are likely to provide habitat for red-listed species. Yet, few studies have investigated the role of forest continuity for the conservation of threatened species. We used species-presence data on red-listed species from 12 taxonomic groups (Spermatophyta, Pteridophyta, Bryophyta, Lichens, Chiroptera, Aves, Squamata, Amphibia, Coleoptera, Lepidoptera, Odonata and Orthoptera) to ascertain if ancient forests … Read more...

Nadeem S., Niazi A.R., Habib K. & Khalid A.N. (2022): A new species of Gyalolechia (Teloschistaceae, lichen-forming Ascomycota) from Pakistan - Nova Hedwigia, 114: 237–249

Gyalolechia pakistanica sp. nov. is described and illustrated from dry hot hilly areas of Khyber Pakhtunkhwa, Pakistan. The new taxon is characterized by a sublobate thallus with short, indistinct lobes, and by relatively large, 8–20 µm long ascospores with variable shape. According phylogenetic analysis of ITS sequences, the new species is sister to G. subbracteata, from which differs by the less distinctly lobed thallus and the larger ascospores. A tabular comparison between the new … Read more...

Fayyaz I., Afshan N.S., Niazi A.R., Khalid A.N. & Orange A. (2022): A new species of Porpidia (Lecideales, Ascomycota) from Pakistan - Nova Hedwigia, 114: 221–235

Porpidia kashmirensis sp. nov. is described from Azad Jammu and Kashmir, Pakistan. ITS and nrLSU sequences confirm its position within the genus Porpidia and, together with its morphology and chemistry, suggest that it is separate from other species of this genus. The species is characterized by a well-developed, pale grey thallus, up to 2.5 mm thick with areoles, containing confluentic acid, immersed apothecia, ascospores relatively small, 13–16 × 6.3–9.9 µm, paraphyses with relatively … Read more...

Simon A., Goffinet B., Wang L.-S., Spribille T., Goward T., Pystina T., Semenova N., Stepanov N.V., Moncada B., Lücking R., Magain N. & Sérusiaux E. (2022): Global phylogeny and taxonomic reassessment of the lichen genus Dendriscosticta (Ascomycota: Peltigerales) - Taxon, 71(2): 256–287

The genus Dendriscosticta (Ascomycota: Peltigerales) encompasses several distinctive lichen-forming fungal species restricted to the Northern Hemisphere. Most are flagship species of old-growth forests with good air quality. A global phylogeny of the genus based on multilocus sequence data (ITS, RPB1, EF-1α, MCM7), model-based phylogenetic methods, and morphological and chemical assessments, reveals a high level of cryptic speciation often associated with restricted geographical distribution … Read more...
