Lendemer J. & Stone D. (2022): Leptogium stancookii, a new name for the western North American lichen referred to as L. cookii whose type corresponds to L. saturninum s. str. - Lichenologist, 54(1): 85-86

As part of a revision of the Leptogium saturninum group in North America, we described L. cookii D. F. Stone & Lendemer as a new species from the western United States and Canada (Stone et al. 2016). The separation of L. cookii from other members of the group was based on a combination of morphological differences (isidium morphology, medulla anatomy and thallus colour) with support from molecular phylogenetic analyses. Unfortunately, in the protologue we selected as type a specimen that had not … Read more...

Kraft M., Scheidegger C. & Werth S. (2022): Stressed out: The effects of heat stress and parasitism on gene expression of the lichen-forming fungus Lobaria pulmonaria - Lichenologist, 54(1): 71-83

Gene expression variation can be partitioned into different components (regulatory, genetic and acclimatory effects) but for lichen-forming fungi, the relative importance of each of these effects is unclear. Here, we studied gene expression in the lichen-forming fungus Lobaria pulmonaria in response to thermal stress and parasitism by the lichenicolous fungus Plectocarpon lichenum. Our experimental procedure was to acclimate lichen thalli to 4 °C over three weeks and then expose them to 15 °C and … Read more...

Feuerstein S., Lücking R. & Borges da Silveira R. (2022): A worldwide key to species of Carbacanthographis (Graphidaceae), with 17 species new to science - Lichenologist, 54(1): 45-70

We provide an updated, worldwide key to species of the genus Carbacanthographis, which is characterized by lirellate ascomata, a carbo- nized excipulum, warty periphysoids, and mostly non-amyloid ascospores. New collections and revision of herbarium material revealed 17 species new to science: Carbacanthographis acanthoamicta, with a thinly corticate thallus, a completely carbonized excipulum, apically warty paraphyses, small and (sub-)muriform ascospores, and salazinic acid; C. acanthoparaphysata, … Read more...

Fernanda de Souza M., Aptroot A. & Spielmann A. (2022): Key to Heterodermia (Physciaceae, Teloschistales) in Brazil, with 15 new species - Lichenologist, 54(1): 25-44

The species of Heterodermia in Brazil have been revised based on literature reports, public databases and examination of 500 recent speci- mens from 15 states. So far, 43 species have been reported in the literature, two of which are not accepted here. We report 10 additional species from Brazil and describe 15 new to science, mostly from the Atlantic rainforest biome, raising the total number to 68, including two still undescribed species from Santa Catarina State. A key to all accepted species … Read more...

Košuthová A., Westberg M. & Wedin M. (2022): A revision of the Rostania occultata (Collemataceae) complex in Fennoscandia - Lichenologist, 54(1): 13-24

The Rostania occultata species complex (‘Collema occultatum s. lat.’) is revised in Fennoscandia and found to consist of four species, all epiphytes on deciduous trees: Rostania effusa A. Košuth., M. Westb. & Wedin sp. nov., R. occultata (Bagl.) Otálora et al., R. pallida A. Košuth., M. Westb. & Wedin sp. nov. and R. populina (Th. Fr.) A. Košuth., M. Westb. & Wedin comb. nov. Rostania effusa and R. pallida are newly described from humid habitats in old-growth boreal coniferous forests, usually … Read more...

Davydov E. & Masson D. (2022): Umbilicaria meizospora comb. nov., a south-western European endemic species of the subgenus Papillophora - Lichenologist, 54(1): 1-12

Detailed morphological investigations and phylogenetic analyses of the ITS/5.8S nrDNA, mtLSU and RPB2 of the Umbilicaria crustulosa– U. spodochroa species complex reveal Umbilicaria hirsuta var. meizospora Harm. to be a separate species. The lectotype has been designated in ANGUC and a new combination Umbilicaria meizospora (Harm.) D. M. Masson & Davydov is proposed. Umbilicaria crustulosa var. badio- fusca was recognized as the heterotypic synonym of U. meizospora and the lectotype was designated … Read more...

Scur M.C., Kitaura M.J., Bianchi de Paula J. & Spielmann A.A. (2022): Contrasting variation patterns in Austroplaca hookeri and Rusavskia elegans (Teloschistaceae, lichenized Ascomycota) in maritime Antarctica - Polar Biology, 45: 101–111

Teloschistaceae is one of the largest lichen-forming fungal lineages, with more than one thousand species worldwide distributed, including areas with extreme environmental conditions, such as Antarctica. Two species of this family, Austroplaca hookeri and Rusavskia elegans were investigated with molecular, morphological, and anatomical data to understand their diversity patterns in maritime Antarctica. These species can be confounded in a superficial identification due to their apparent similarities … Read more...

Zorn S., Carvalho A., Bento H., Gambarato B., Pedro G., da Silva A., Gonçalves R., Da Rós P. & Silva M. (2022): Use of fungal mycelium as biosupport in the formation of lichen-like structure: recovery of algal grown in sugarcane molasses for lipid accumulation and balanced fatty acid profile - Membranes, 12(3): 258 [15 p.]

In this study, a lichen-like structure was obtained through the production of a unique biomass, formed by algae cells of Scenedesmus obliquus adhering to the mycelium of filamentous fungal Mucor circinelloides. This structure was composed in two steps; in the first one, microalgal cells and spores were incubated separately, and in the second one, after 72 h of growth, isolated, mature mycelium was harvested and added to cell culture. For spores’ incubation, a culture medium containing only 2 g·L−1 … Read more...

Ručová D., Đorđević T., Baláž M., Weidinger M., Lang I., Gajdoš A. & Goga M. (2022): Investigation of calcium forms in lichens from travertine sites - Plants, 11(5): 620 [13 p.]

Lichens are symbiotic organisms with an extraordinary capability to colonise areas of extreme climate and heavily contaminated sites, such as metal-rich habitats. Lichens have developed several mechanisms to overcome the toxicity of metals, including the ability to bind metal cations to extracellular sites of symbiotic partners and to subsequently form oxalates. Calcium is an essential alkaline earth element that is important in various cell processes. Calcium can serve as a metal ligand but can … Read more...

Di Nuzzo L., Masoni A., Frizzi F., Bianchi E., Castellani M.B., Balzani P., Morandi F., Sozzi Y., Vallese C., Santini G. & Benesperi R. (2022): Red wood ants shape epiphytic lichen assemblages in montane silver fir forests - iForest - Biogeosciences and Forestry, 15(1): 71–76

The Formica rufa group comprises several ant species which are collectively referred to as “red wood ants” (hereafter RWA). These species have key roles in forest ecosystems, where they are ecologically dominant and greatly influence the dynamics of the habitat they colonise. Various studies have shown how their trophic activity may affect other organisms, which include both other invertebrates and plants. We can therefore hypothesize that their presence could affect the taxonomic and functional … Read more...
