Soto Medina E., Aptroot A. & Lücking R. (2022): New records of lichen genera and species for Colombia, Revista de la Academia Colombiana de Ciencias Exactas, Físicas y Naturales, 46(180): 751–757

Dirina paradoxa, Heterocyphelium triseptatum, Julella sublactea, Opegrapha aurantiaca, Peltula steppae, Sarcographina cyclospora and Schistophoron tenue are reported for the first time in Colombia. The genera Dirina, Heterocyphelium Sarcographina and Schistophoron are reported for the first time in Colombia. These lichens mainly originate from dry ecosystems where previous collections of lichenized fungi have been uncommon. Key words: crustose lichens; tropic; taxonomy. Read more...

Исмаилов А.Б. [Ismailov A.B.] (2022): Анализ разнообразия и функциональных признаков эпифитных лишайников в лесах Дагестана разных формаций [Analysis of diversity and functional traits of epiphytic lichens in Dagestan forests of different formations], Юг России: экология, развитие [South of Russia: ecology, development], 17(3): 125–134

[in Russian with English abstract: ] Aim. The structure of forest communities changes along the altitude gradient, which determines the composition of epiphytic lichens. The aim of the study is to compare the species composition and functional characteristics of epiphytic lichens in Dagestan forests of different formations to identify key differences in the lichen flora. Material and Methods. Data on diversity and structure of 334 species of epiphytic lichens … Read more...

Lumbsch H.T. & Türk R. (2022): Varicellaria velata occurs in the Alps, Herzogia, 35(1): 74–76

Varicellaria velata in its current circumscription has a worldwide distribution and is common in tropical and subtropical habitats but also extends into the temperate zone. In Europe it has a subatlantic distribution and has also been recorded from a single locality in Austria for the Alps. This record has recently been interpreted as dubious and consequently, the species was not listed in recent checklists of the Alps and Austria. We here report a new collection of this species from Austria … Read more...

Gaya E., Motato-Vásquez V. & Lücking R. (2022): Diversity of fungi of Colombia, In: de Almeida R.F., Lücking R., Vasco-Palacios A.M., Gaya E. & Diazgranados M. (eds), Catalogue of Fungi of Colombia, p. 74–76, Kew Publishing, Royal Botanic Gardens, Kew

Book chapter. This chapter provides a brief overview of the diversity of fungi of Colombia, both in comparison with other organisms and in a global context, including an assessment of the current state of knowledge and an estimate of the actual species richness. The current checklist of fungi of Colombia, including lichenised and fungus-like organisms unrelated to the true Fungi, comprises 7,241 species. Assessments of biodiversity-rich countries are usually based on plants and vertebrates, but … Read more...

Vasco-Palacios A.M. & Moncada B. (2022): Two centuries of mycological history in Colombia, In: de Almeida R.F., Lücking R., Vasco-Palacios A.M., Gaya E. & Diazgranados M. (eds), Catalogue of Fungi of Colombia, p. 33–43, Kew Publishing, Royal Botanic Gardens, Kew

Book chapter. Current knowledge about the Colombian funga results from countless expeditions, researchers, and national and foreign institutions that have contributed to the development of mycology in Colombia for more than two centuries. This historical timeline will probably remain incomplete because several historical accounts are difficult to track down, but four different periods are highlighted: 1. Fungal knowledge from pre-Hispanic times is still incomplete despite efforts to compile … Read more...

Borisov S.A., Luzina O.A., Khvostov M.V., Tolstikova T.G. & Salakhutdinov N.F. (2022): Synthesis and pharmacological evaluation of (+)-usnic acid derivatives as hypoglycemic agents, Molbank, 2022(4): M1459 [7 p.]

Usnic acid is produced by lichens and exhibits different biological properties, including hypoglycemic ones. However, this effect becomes noticeable only at relatively high doses, something that may lead to some adverse effects. The chemical modification of the molecule is able to enhance its safety profile and its hypoglycemic properties. We synthesized six enamine derivatives of (+)-usnic acid, and two of them are novel. All compounds were evaluated for the hypoglycemic effect after oral introduction … Read more...

Shelyakin M., Malyshev R., Silina I., Zakhozhiy I. & Golovko T. (2022): UV‑B induced changes in respiration and antioxidant enzyme aktivity in the foliose lichen Peltigera aphthosa (L.) Willd., Acta Physiologiae Plantarum, 44: 116 [13 p.]

Lichens are phototrophic organisms tolerant to adverse environmental conditions. However, the mechanisms underlying their stress tolerance are not fully understood. For photosynthetic organisms depending on solar radiation, UV-B radiation (280–320 nm) acts as a stress factor. We studied the pro-/antioxidant and respiratory metabolism of Peltigera aphthosa to identify adaptive responses of lichen to a physiological dose of UV-B radiation (14 kJ day− 1 for 10 days). A browning of the upper … Read more...

Kumar T.K., Siva B., Anand A., Anusha K., Mohabe S., Reddy A.M., Le Devehat F., Tiwari A.K., Boustie J. & Babu K.S. (2022): Comprehensive lichenometabolomic exploration of Ramalina conduplicans Vain [sic!] using UPLC-Q-ToF-MS/MS: An identification of free radical scavenging and anti-hyperglycemic constituents, Molecules, 27(19): 6720 [14 p.]

In this study, we propose ultra-performance liquid chromatography coupled with quadrupole/time-of-flight mass spectrometry (UPLC-QToF-MS/MS)-guided metabolite isolation as a choice analytical approach to the ongoing structure–activity investigations of chemical isolates from the edible lichen, Ramalina conduplicans Vain. This strategy led to the isolation and identification of a new depside (5) along with 13 known compounds (1–4, 6–14), most of which being newly described in this lichen species. … Read more...

Xu H., Wang L., Feng X. & Gong X. (2022): Core taxa and photobiont‑microbial interaction within the lichen Heterodermia obscurata (Physcsiaceae, Heterodermia), Symbiosis, 86: 187–204

The dual nature of fungal-algal lichen symbioses is extended by other microbial associations. Increasing evidence has confirmed that lichens are successful holobionts composed of complex and multiple species. Specific interactions between these microbes contributed to the lichens’ health, growth and fitness. Previous studies suggested that the composition of microorganisms in lichens was potentially influenced by the genetic background of the host-symbiont, large-scale geography or different … Read more...
