Ingle K.K., Nayaka S. & Upreti D.K. (2024): The lichen genus Pseudopyrenula (Trypetheliaceae) in India - The Lichenologist, 56(1): 21-26

A survey of the lichen genus Pseudopyrenula in India is presented, with morphotaxonomic accounts of all six accepted species. Two species, P. himalayana and P. megaspora, are new to science. Both species resemble P. staphyleae but have a lichenized thallus and eccentric ostiole. Furthermore, P. himalayana differs from P. staphyleae in having immersed perithecia and narrower ascospores, while P. megaspora differs in the larger ascospores. Detailed descriptions of the new species are presented, together … Read more...

Ptach-Styn Ł., Guzow-Krzemińska B., Lendemer J.C., Tønsberg T. & Kukwa M. (2024): Phylogeny of the genus Loxospora s.l. (Sarrameanales, Lecanoromycetes, Ascomycota), with Chicitaea gen. nov. and five new combinations in Chicitaea and Loxospora - MycoKeys, 102: 155–181

Loxospora is a genus of crustose lichens containing 13 accepted species that can be separated into two groups, based on differences in secondary chemistry that correlate with differences in characters of the sexual reproductive structures (asci and ascospores). Molecular phylogenetic analyses recovered these groups as monophyletic and support their recognition as distinct genera that differ in phenotypic characters. Species containing 2’-O-methylperlatolic acid are transferred to the new genus, … Read more...

Timdal E., Evankow A.M., Opedal V. & Fjelde M.O. (2024): Lecania lepidota, a new lichen species from pollarded Fraxinus excelsior in oceanic, old-growth deciduous forests in Norway - Graphis Scripta, 36(1): 1–14

The new lichen species Lecania lepidota is described from two localities in oceanic, old-growth, deciduous forests (boreo-nemoral rainforest) in SW Norway, growing near the base of pollarded Fraxinus excelsior. The generic placement is uncertain, as the ITS marker differs significantly from all other available ITS sequences and the mtSSU marker indicates sister relationship with Lecania croatica, a species of uncertain position in the Ramalinaceae. The species is morphologically most similar … Read more...

Pérez-Vargas I., Tuero-Septién J., Rancel-Rodríguez N.M., Pérez J.A. & Blázquez M. (2024): Patterns of endemism in lichens: another paradigm-shifting example in the lichen genus Xanthoparmelia from Macaronesia - Journal of Fungi, 10(3): 166 [18 p.]

It has long been assumed that lichen-forming fungi have very large distribution ranges, and that endemic species are rare in this group of organisms. This is likely a consequence of the “everything small is everywhere” paradigm that has been traditionally applied to cryptogams. However, the description of numerous endemic species over the last decades, many of them in oceanic islands, is challenging this view. In this study, we provide another example, Xanthoparmelia ramosae, a species that is … Read more...

Kubiak D. (2024): Notes on Candelariella reflexa s. str. (Ascomycota, Candelariaceae) in Poland - Acta Mycologica, 58: 183018 [5 p.]

This paper presents new localities of the epiphytic lichen Candelariella reflexa (Nyl.) Lettau found in NE Poland. The species has been reported in Poland for over two decades, but the progress of research on the taxonomy of this genus requires confirmation of the data by the currently accepted taxonomic approach. The paper also discusses the diagnostic features of the species that help distinguish it from other similar taxa. Keywords: lichens; Candelinella; Opeltiella; new localities; NE Poland. Read more...

Pinna D. (2024): Physical and mechanical methods for the removal of lithobionts—A review - Coatings, 14(3): 272 [21 p.]

This paper describes and discusses the results of scientific experiences of the physical and mechanical methods used to control and inhibit the growth of lichens and biofilms that grow on indoor and outdoor historical stone artworks. It provides an extensive selection and examination of international papers published in the last two decades on the issue. The great advantage of physical and mechanical methods lies in the lack of potential risks associated with the irreversible application of microbicides. … Read more...

Contardo T. & Loppi S. (2024): Assessing environmental justice at the urban scale: The contribution of lichen biomonitoring for overcoming the dichotomy between proximity-based and distribution-based approaches - Atmosphere, 15(3): 275 [15 p.]

In this study, we tested the use of lichen biomonitoring techniques for the assessment of air quality disparities at the urban scale. We based our evaluation on the results of a previous lichen biomonitoring study carried out in Milan (Northern Italy), which estimates the contamination by potentially toxic elements (PTEs) and its distribution over the area, also providing an evaluation of the main emission sources. Therefore, we used the traditional methodologies for environmental justice assessment: … Read more...

Grube M. (2024): [Chapter 6] Lichens - In: Hsueh Y.-P. & Blackwell M. (eds), Fungal Associations, The Mycota 9, p. 145–178, Springer, Cham

Lichenized fungi initiate their symbiotic structures from microscopic stages after recog-nition of compatible algae. The partnerships ultimately emerge as complex macroscopic phenotypes which are unrivaled in the fungal kingdom by their resilience and durability. This chapter presents an overview of lichen symbioses and covers the morphology and systematics of the fungal phenotypes, as well as their associations with diverse photobionts. This is followed by a coarse overview of eco-physiology and … Read more...

Wang Y., Wei X., Hu Y. & Xu J.-R. (2024): Umbilicaria muhlenbergii: A model for studying molecular mechanisms regulating initial fungal symbiotic interactions with algal cells - In: Hsueh Y.-P. & Blackwell M. (eds), Fungal Associations, The Mycota 9, p. 181–193, Springer, Cham

Lichens are known for their importance in evolution and ecology but our knowledge of molecular mechanisms regulating symbiont interactions in lichen symbiosis is very lim-ited. Recent studies have shown that Umbilicaria muhlenbergii has a relative fast growth rate and is amenable to molecular genetic studies for efficiently generating transformants and targeted gene disruption mutants. It is the only known dimorphic lichen-forming fungus, and pseudohyphal growth is associated with symbiotic interactions … Read more...

Nakai R., Munekawa S., Murai Y., Ohmura Y. & Tani K. (2024): Diversity profiling of microbiomes associated with selected alpine plants and lichens from Mt. Suisho, Japan - Microbiology Resource Announcements, 0:e01270-23

[preprint on line version, to be updated] We report 16S rRNA gene amplicon data for the microbiomes in selected alpine plants (genera Artemisia, Parnassia, and Phyllodoce) and lichens (genera Cladonia and a mixture of Miriquidica and Rhizocarpon) from Mt. Suisho, Japan. Most of these samples were dominated by Pseudomonadota, while some contained the rarely cultivated phylum Vulcanimicrobiota (Candidatus Eremiobacterota/WPS-2). Keywords: alpine, plant, lichen, microbiome. Read more...
