McDonough A.M., Bird A.W., Luciani M.A. & Todd A.K. (2022): Establishing trace element concentrations for lichens and bryophytes in the ring of fire region of the Hudson Bay Lowlands, Ontario, Canada, Environmental Monitoring and Assessment, 194: 226 [13 p.]

Peatlands dominate the landscape of the Hudson Bay Lowlands in Ontario, Canada. Recently, mineral deposits of chromium (Cr), nickel (Ni), and copper (Cu) were discovered in the region and anticipated future industrial mining operations have the potential to impact the environment. Lichens and bryophytes are considered excellent biomonitors and indicators of deposition, deriving their nutrients directly from the atmosphere. Trace element concentrations in lichens and bryophytes have not been reported … Read more...

Nekhoroshev S.V., Leonov V.V., Nekhorosheva A.V., Gornikov N.V., Kot M.F. & Karpova Ya.A. (2022): Antimicrobial activity of some lichen extracts, Pharmaceutical Chemistry Journal, 55(11): 1190–1195

[Translated from the Russian original published in Khimiko-Farmatsevticheskii Zhurnal, Vol. 55, No. 11, pp. 22–27, November, 2021.] Cladonia rangiferina is a bushy lichen of the genus Cladonia and has a multi-regional distribution. This plant contains usnic acid as the main biologically active substance and has been tested against some opportunistic microorganisms. Among the studied C. rangiferina extracts, only glycerol extracts obtained at an extraction temperature of 40°C were biologically … Read more...

Veres K., Csintalan Y., Laufer Y., Engel R., Szabó K. & Farkas E. (2022): Photoprotection and high-light acclimation in semi-arid grassland lichens – a cooperation between algal and fungal partners, Symbiosis, 86: 33–48

Abstract In lichens, each symbiotic partner cooperates for the survival of the symbiotic association. The protection of the susceptible photosynthetic apparatus is essential for both participants. The mycobiont and photobiont contribute to the protection against the damaging effect of excess light by various mechanisms. The present study investigated the effect of seasonality and microhabitat exposure on photoprotection and photoacclimation in the photo- and the mycobiont of six lichen species with … Read more...

Xavier-Leite A.B., Cáceres M.E.S., Aptroot A., Moncada B., Lücking R. & Goto B.T. (2022): Phylogenetic revision of the lichenized family Gomphillaceae (Ascomycota: Graphidales) suggests post-K–Pg boundary diversification and phylogenetic signal in asexual reproductive structures, Molecular Phylogenetics and Evolution, 168: 107380 [23 p.]

We present the first broad molecular-phylogenetic revision of the lichenized family Gomphillaceae, based on 408 newly generated sequences of the mitochondrial SSU rDNA and nuclear LSU rDNA, representing 342 OTUs. The phylogenetic analysis of 20 out of the 28 currently accepted genera resulted in 48 clades. Twelve genera were resolved as monophyletic: Actinoplaca, Arthotheliopsis, Bullatina, Caleniopsis, Corticifraga, Gomphillus, Gyalectidium, Gyalidea, Jamesiella, Rolueckia, Rubrotricha, and … Read more...

Dal Forno M., Lawrey J.D., Moncada B., Bungartz F., Grube M., Schuettpelz E. & Lücking R. (2022): DNA barcoding of fresh and historical collections of lichen‐forming basidiomycetes in the genera Cora and Corella (Agaricales: Hygrophoraceae): A success story?, Diversity, 14(4): 284 [34 p.]

Lichen collected worldwide for centuries have resulted in millions of specimens deposited in herbaria that offer the potential to assess species boundaries, phenotypic diversification, ecology, and distribution. The application of molecular approaches to historical collections has been limited due to DNA fragmentation, but high-throughput sequencing offers an opportunity to overcome this barrier. Here, we combined a large dataset of ITS sequences from recently collected material and historical collections, … Read more...

Shevkar C., Armarkar A., Weerasinghe R., Maduranga K., Pandey K., Behera S.K., Kalia K., Paranagama P. & Kate A.S. (2022): Cytotoxic bioxanthracene and macrocyclic polyester from endolichenic fungus Talaromyces pinophilus: In-vitro and in-silico analysis, Indian Journal of Microbiology, 62(2): 204–214

Lichens are used in folklore medicines across the globe for wound healing and to treat skin disorders and respiratory diseases. They are an intricate symbiosis between fungi and algae with the domination of fungal counterparts. Recent research studies pointed out that yeast is a third major partner in lichens. Endolichenic fungi (ELF) are also a part of this complex miniature ecosystem. The highly competitive environment of lichens compels ELF to produce toxic metabolites which are comparatively less … Read more...

Diederich P., Millanes A.M., Etayo J., van den Boom P.P.G. & Wedin M. (2022): Finding the needle in the haystack: a revision of Crittendenia, a surprisingly diverse lichenicolous genus of Agaricostilbomycetes, Pucciniomycotina, Bryologist, 125(2): 248–293

While most lichenicolous fungi belong to the Ascomycota, c. 5% of them are members of the Basidiomycota. Among these, the poorly known genus Crittendenia in the Pucciniomycotina has recently been described for lichenicolous fungi with minuscule needle-like synnematous basidiomata. Although only two species were hitherto known, the wide observed host-spectrum suggested a larger number of mainly host-specific species. A classical revision using morphological characters alone proved to be virtually … Read more...

Lee B.G. & Hur J.-S. (2022): A new lichenized fungus, Psoroglaena humidosilvae, from a forested wetland of Korea, with a taxonomic key to the species of Psoroglaena, Journal of Fungi, 8(4): 392 [13 p.]

Psoroglaena humidosilvae Lee is described as a new lichen species from a wetland forest in South Korea. The new species is distinct from P. stigonemoides (Orange) Henssen by little projections locally present on the thallus; smaller, paler, and globose perithecia; smaller asci; and smaller ascospores generally 3-septate. Molecular analyses employing internal transcribed spacer (ITS), mitochondrial small subunit (mtSSU), and nuclear large subunit ribosomal RNA (LSU) sequences strongly support P. humidosilvae … Read more...

Elečko J., Vilková M., Frenák R., Routray D., Ručová D., Bačkor M. & Goga M. (2022): A comparative study of isolated secondary metabolites from lichens and their antioxidative properties, Plants, 11(8): 1077 [14 p.]

Free radicals play a critical role in the chemical processes that occur in all cells. Pharmaceutical companies manufacture a variety of synthetically prepared antioxidants, but it is known that many of these can be carcinogenic. As a result, efforts are being made to find natural antioxidants that do not have these side effects. Lichens may be suitable candidates because they contain secondary metabolites with proven antioxidant properties. This could be explained by the presence of compounds with … Read more...

Vicol I. & Mihăilescu S. (2022): A biogeographical study of red listed lichen species at temporal and spatial scales within protected and non‑protected areas, Scientific Reports, 12: 898 [9 p.]

The present study is focused on the temporal and spatial distribution of red listed lichen (RLL) species identifed in both non-protected areas (NPAs) and protected areas (PAs) in Romania. This study revealed diferent scenarios of RLL based on two major patterns: (1) the fate of RLL before and after their designation in the red list in Romania and (2) the fate of RLL before and after the designation of PAs in Romania. Generally, the occurrences of RLL were well represented in time and space … Read more...
