Hawksworth D. (2005): To be or not to be a lichen - Nature, 433: 468

Work by Mats Wedin and colleagues highlights both the versatility of fungi and the complications these unsung organisms pose for the biologist. Two of the ways in which fungi make a living are as saprophytes, drawing sustenance from decaying matter, and as lichens, in which they form an intimate relationship with green algae or photosynthetic bacteria. Evidently, however, a single fungal species can adopt either lifestyle according to circumstance (New Phytol. 164, 459–465; 2004). Read more...

Wang S., Zhao G., Niu D., Wang L., Ren X., Wu J. & Qu H. (2024): Three new species and a new record of the lichen genus Peltula (Peltulaceae) from Helan Mountain in China - Biology, 13(8): 590 [15 p.]

In this study, a systematic taxonomic analysis was carried out on the lichen genus Peltula, collected from Helan Mountain in China; three new species (Peltula helanense, P. overlappine, and P. reticulata) and a new record (P. crispatula (Nyl.) Egea) for China were identified. Four species were identified by morph-anatomical, chemical, and phylogenetic analyses by combining two gene loci (ITS and LSU). Peltula helanense is with tiny individual thalli up to 1mm, attached by creamy-white cylindrical … Read more...

Gerasimova J.V., Beck A., Scheunert A. & Kulkarni O. (2024): De novo genome assembly of Toniniopsis dissimilis (Ramalinaceae, Lecanoromycetes) from long reads shows a comparatively high composition of biosynthetic genes putatively involved in melanin synthesis - Genes, 15(8): 1029 [14 p.]

Lichens have developed numerous adaptations to optimize their survival in various environmental conditions, largely by producing secondary compounds by the fungal partner. They often have antibiotic properties and are involved in protection against intensive UV radiation, pathogens, and herbivores. To contribute to the knowledge of the arsenal of secondary compounds in a crustose lichen species, we sequenced and assembled the genome of Toniniopsis dissimilis, an indicator of old-growth forests, using … Read more...

Xavier-Leite A.B., Goto B.T., Cáceres M.E.S. & Lücking R. (2024): Reclassification of species in the lichenized family Gomphillaceae Walt. Watson ex Hafellner (Ascomycota: Graphidales) using morphology-based phylogenetic binning - Cryptogamie, Mycologie, 45(8): 83–99

Results of phylogenetic analyses are often not translated into formal classifications, because only a portion of the taxa have been sequenced, making the placement of the remaining taxa unclear. This is the case for Gomphillaceae Walt. Watson ex Hafellner, which currently includes 422 accepted lichenized and 18 lichenicolous or fungicolous species, with only 27% having sequence data available. A separate, expanded phylogeny of the family recognized at least 19 further genus-level lineages, in addition … Read more...

Casanova Municchia A., Giordani P., Taniguchi Y. & Caneva G. (2024): Assessing the impact of lichens on Saint Simeon Church, Paşabağ Valley (Cappadocia, Turkey): Potential damaging effects versus protection from rainfall and winds - Applied Science, 14: 6943 [20 p.]

The impact of lichens on the conservation of monuments, such as the World Heritage Site (WHS) of Cappadocian churches, presents a multifaceted challenge for conservators. Previous studies have shown that lichens can both induce deterioration processes of stone through their penetration into the substrate and chemical interactions as well as provide bioprotection, forming encrustations including calcium oxalate layers, which help mitigating the effects of weathering, reducing water penetration and … Read more...

Darmostuk V., Sira O. & Govorun O. (2024): New data about overlooked terricolous lichen-forming and lichenicolous fungi of Ukraine - Folia Cryptogamica Estonica, 61: 59–66

The new distribution data on rarely collected terricolous lichen species in Ukraine, Agonimia globulifera, Enchylium limosum, Epiphloea byssina, Gregorella humida, Sarcosagium campestre, Steinia geophana, Scytinium biatorinum, S. schraderi, and Verrucaria bryoctona, are provided. Notably, A. globulifera and S. biatorinum have been reported for the first time in the lowland part of Ukraine. Furthermore, the lichenicolous fungus Llimoniella terricola, growing on Epiphloea byssina, is reported for the … Read more...

Lücking R., Moncada B. & Bungartz F. (2024): Stochastic versus deterministic assembly of oceanic island biota: leaf-dwelling lichens on the Galápagos and on Cocos Island - Frontiers of Biogeography, 17: e133819 [15 p.]

We used a simulation approach to test whether species composition on oceanic islands follows deterministic assembly rules based on probabilities of successful dispersal and establishment. The study was performed with two island biota in the eastern Pacific: the Galápagos, dominated by dry vegetation and montane humid forest, and Cocos Island, covered by wet tropical forest. We used leaf-dwelling (foliicolous) lichens as the study group and compiled occurrence data from previous studies on both island … Read more...

Ossowska E.A., Guzow‑Krzemińska B., Kukwa M., Malíček J., Schiefelbein U., Thell A. & Kosecka M. (2024): The application of haplotypes instead of species‑level ranks modifies the interpretation of ecological preferences in lichen symbiont interactions in Parmelia - Scientific Reports, 14: 19682 [11 p.]

The analysis of the interaction between main bionts (mycobiont and photobiont) in the lichen symbiosis delivers substantial information about their preferences in the selection of symbiotic partners, and their ecological preferences. The selectivity in the Parmelia genus has been defined as strong so far. However, data on this lichen genus, which includes several widely distributed species, are biogeographically limited. Therefore, using specialization indicators and extended sampling, in this study, … Read more...

Amo de Paz G., Divakar P.K., Crespo A., Lumbsch H.T. & Rico V.J. (2024): The first miniature, small foliose, brown Xanthoparmelia in the Northern Hemisphere - Journal of Fungi, 10: 603 [16 p.]

The genus Xanthoparmelia includes several subcrustose, squamulose, small foliose, and small subfruticose species, primarily in the Southern Hemisphere. Here, we report on the first small foliose species lacking usnic acid in the genus occurring in the Holarctic. The species has been previously known as Lecanora olivascens Nyl., but subsequent studies of the morphology, secondary chemistry, and molecular data of the nuITS rDNA indicate that this species instead belongs to Xanthoparmelia. Consequently, … Read more...
