[in Russian with English summary:] Four species of lichens, four species of fungi and one species of parasitic myxomycete are reported for the first time for the Central Forest State Natural Biosphere Reserve (CFR). Data on localities and habitats are provided for all species; nearest known localities in Tver Region are discussed. Nowadays the list of lichens and allied fungi of the CFR counts 413 species from 157 genera. Keywords: lichens, ichenicolous fungi, lichen flora, Central Forest … Read more...

Bergauer M., Dembicz I., Boch S., Willner W., Babbi M., Blank‑Pachlatko J., Catalano C., Cykowska‑Marzencka B., Gehler J., Guarino R., Keller S., Moysiyenko I., Vynokurov D., Widmer S. & Dengler J. (2022): Scale‑dependent patterns and drivers of vascular plant, bryophyte and lichen diversity in dry grasslands of the Swiss inneralpine valleys, Alpine Botany, 132: 195–209

The inner-alpine dry valleys of the Swiss Alps are characterized by subcontinental climate, leading to many peculiarities in dry grassland species composition. Despite their well-known uniqueness, comprehensive studies on biodiversity patterns of the dry grasslands in these valleys were still missing. To close this gap, we sampled 161 10-m2 vegetation plots in the Rhône, Rhine and Inn valleys, recording vascular plants, terricolous bryophyte and lichen species, as well as environmental data. … Read more...

Ndhlovu N.T., Minibayeva F. & Beckett R.P. (2022): Unpigmented lichen substances protect lichens against photoinhibition of photosystem II in both the hydrated and desiccated states, Acta Physiologiae Plantarum, 44: 123 [7 p.]

Lichen secondary metabolites have been suggested to play a great diversity of roles in lichen biology by acting as UV screens, antimicrobials, herbivore deterrents or allelopathic compounds. However, evidence is also beginning to accumulate that in addition to these roles, even faintly pigmented or unpigmented lichen substances can reduce photoinhibition caused by high levels of photosynthetically active radiation (PAR). Here we used an acetone rinsing technique to remove lichen substances … Read more...

Mkhize K.W.G., Minibayeva F. & Beckett R.P. (2022): Lichen photobionts can be hardened to photoinhibition by pretreatment with light, Acta Physiologiae Plantarum, 44: 122 [10 p.]

Lichens often grow in microhabitats where they receive more light than they are capable of using to fx carbon. Unless regulated, this excess energy can end up activating oxygen, thereby forming reactive oxygen species (ROS). These ROS can damage the photosynthetic apparatus and other cellular components, causing photoinhibition and photo-oxidative stress. Tolerance to high light theoretically can be achieved in a variety of ways, but for lichen photobionts, our knowledge of the precise mechanisms … Read more...

[in French, additionally with Esperanto and English abstracts] Description of the new lichen genus Verrucariopsis Gueidan, Monnat & Cl. Roux gen. nov. whose type species, V. suaedae Gueidan, Monnat & Cl. Roux sp. nov., was discovered on the coast of Brittany and Loire – Atlantique, on the upper schorre of rias where it grows on stems of Suaeda vera, on the supralittoral zone. The morpho – anatomical and phylogenetic study showed that Verrucariopsis belongs to the Verrucariaceae family and that … Read more...

Vasco-Palacios A.M., Lücking R., Moncada B., Palacio M. & Motato-Vásque V. (2022): A critical assessment of biogeographic distribution patterns of Colombian fungi, In: de Almeida R.F., Lücking R., Vasco-Palacios A.M., Gaya E. & Diazgranados M. (eds), Catalogue of Fungi of Colombia, p. 121–137, Kew Publishing, Royal Botanic Gardens, Kew

Book chapter. This chapter attempts to assess the distribution patterns of three selected groups of fungi, namely polypores, ectomycorrhizal fungi (EcM), and lichenised fungi in Colombia. Assessing the biogeography of fungi is difficult because of two key issues: 1. information gaps on their distribution and biology in biodiversity-rich countries, such as Colombia, and 2. the traditional, phenotype-based species concepts, which make it difficult to recognise cryptic species or species complexes. … Read more...

Frisch A., Ohmura Y., Holien H. & Bendiksby M. (2022): A phylogenetic survey of the ascomycete genus Arthrorhaphis (Arthrorhaphidaceae, Lecanoromycetes) including new species in Arthrorhaphis citrinella sensu lato, Taxon, 71(5): 936–962

The genus Arthrorhaphis is a group of ascomycetes comprising lichenised and non-lichenised taxa from temperate to arctic-alpine regions in both hemispheres. Nine species and two infraspecific taxa are currently recognised. Their delimitation, inter-relationships, and phylogenetic placement remain poorly understood. We have used an integrative taxonomic approach to assess taxon limits, phylogenetic placement of the family, and to test the hypothesis that transition to lichenisation has happened … Read more...
