Kantvilas G. (2023): Three new species of siphuloid lichens, with a first key to the genus Parasiphula - The Lichenologist, 55(1): 17-25

The term ‘siphuloid’ is introduced for a suite of distinct lichen genera with a superficially similar foliose to fruticose morphology, notably Siphula, Siphulella, Siphulopsis, Parasiphula and Knightiellastrum. Three new species are described: Parasiphula squamosa Kantvilas (from Tasmania and New Zealand), characterized by a whitish grey, squamulose or minutely foliose thallus lacking lichen substances or containing traces of atranorin; Siphula capensis Kantvilas (from southern Africa), containing … Read more...

Pfeffer B., Lymbery C., Booth B. & Allen J. (2023): Chromosomal genome sequence assembly and mating-type (MAT) locus characterization of the leprose asexual lichenized fungus Lepraria neglecta (Nyl.) Erichsen - The Lichenologist, 55(1): 41-50

Complete chromosomal-level assemblies of fungal genomes are rare. The intimate ecological symbioses and complex reproduction strategies utilized by fungi make highly contiguous, gapless genome assemblies particularly difficult. Here, we use long-read sequencing on the Oxford Nanopore Technology MinION platform to sequence and assemble the genome of Lepraria neglecta (Ascomycota, Lecanorales). In addition to eight contigs ascribable to chromosomes, six of which are assembled telomere-to-telomere, … Read more...

Wang W., Abas A., Wei X., Qian X. & Wei J. (2023): Two new species of the lichenized genus Lasioloma (Byssolomataceae) from Asia - The Lichenologist, 55(1): 27-33

Two new species of the lichenized genus Lasioloma are described from Asia: Lasioloma longiramosum W. C. Wang & A. Abas (collected from Malaysia), is characterized by a distinct woolly prothallus between dispersed thallus patches, comparatively small, muriform ascospores, long filiform conidia (main branch 22–28 μm in length, the other three branches 65–80 μm) and a foliicolous habitat; L. verrucosum W. C. Wang & X. L. Wei (collected from China), is characterized by a warted thallus, filiform … Read more...

Zhurbenko M. (2023): Clypeococcum wedinii (Dothideomycetes), a new lichenicolous fungus on Bunodophoron, with an updated key to species of Clypeococcum - The Lichenologist, 55(1): 35-39

Clypeococcum wedinii, a pyrenocarpous ascomycete growing on the lichen genus Bunodophoron in Chile and New Zealand, is described as new to science. It differs from other Clypeococcum species in the combination of the following characteristics: a conspicuous gall formation, scattered, loose to dense stromatic growths sometimes looking like a clypeus, an ascomatal wall composed of both textura intricata and angularis in surface view, a non-amyloid hymenium, an absence of ostiolar filaments, 8-spored … Read more...

Bokhorst S., Bjerke J.W., Phoenix G.K., Jaakola L., Mæhre H.K. & Tømmervik H. (2023): Sub-arctic mosses and lichens show idiosyncratic responses to combinations of winter heatwaves, freezing and nitrogen deposition - Physiologia Plantarum, 175(2): e13882 [18 p.]

Arctic ecosystems are increasingly exposed to extreme climatic events throughout the year, which can affect species performance. Cryptogams (bryophytes and lichens) provide important ecosystem services in polar ecosystems but may be physiologically affected or killed by extreme events. Through field and laboratory manipulations, we compared physiological responses of seven dominant sub-Arctic cryptogams (three bryophytes, four lichens) to single events and factorial combinations of mid-winter heatwave … Read more...

Stanton D.E., Ormond A., Koch N.M. & Colesie C. (2023): Lichen ecophysiology in a changing climate - American Journal of Botany, 110(2): e16131 [14 p.]

Lichens are one of the most iconic and ubiquitous symbioses known, widely valued as indicators of environmental quality and, more recently, climate change. Our understanding of lichen responses to climate has greatly expanded in recent decades, but some biases and constraints have shaped our present knowledge. In this review we focus on lichen ecophysiology as a key to predicting responses to present and future climates, highlighting recent advances and remaining challenges. Lichen ecophysiology … Read more...

(2023): Larvicidal activity and docking study of Ramalina complanata and Cladonia verticillaris extracts and secondary metabolites against Aedes aegypti - Industrial Crops and Products, 195: 116425 [8 p.]

Highlights ● Ramalina complanata and Cladonia verticillaris extracts showed larvicidal activity. ● Fumarprotocetraric acid was a better larvicidal as Divaricatic acid. ● The TRP286 residue may have contributed to the very good activity of FUM. The Aedes aegypti mosquito is the main vector of the arboviruses that cause Zika, Yellow Fever, Dengue, and Chikungunya, incapacitating diseases that may even be fatal. There are still no vaccines for any of these viruses. Therefore, the … Read more...

Yañez O., Osorio M.I., Osorio E., Tiznado W., Ruíz L., García C., Nagles O., Simirgiotis M.J., Castañeta G., Areche C. & García-Beltrán O. (2023): Antioxidant activity and enzymatic of lichen substances: A study based on cyclic voltammetry and theoretical - Chemico-Biological Interactions, 372: 110357 [10 p.]

The antioxidant activity of nine lichen substances, including methylatrarate (1), methyl haematommate (2), lobaric acid (3), fumarprotocetraric acid (4), sphaerophorin (5), subsphaeric acid (6), diffractaic acid (7), barbatolic acid (8) and salazinic acid (9) has been determined through cyclic voltammetry. The compounds 1–4 presented slopes close to the Nernst constant of 0.059 V, indicating a 2H+/2e− relation between protons and electrons, as long as the compounds 5, 6, 7, 8, and 9 present slopes … Read more...
