Kitaura M.J., Scur M.C., Spielmann A.A. & Lorenz A.P. (2022): An integrative study of Pannaria hookeri (Ascomycota lichenized) from Argentina and the update of the taxon circumscription based on specimens from the Northern and Southern Hemispheres - Acta Botanica Brasilica, 36: e2021abb0357 [10 p.]

Pannaria hookeri (Borrer ex Sm.) Nyl. is reported as a bipolar cyanolichen that occurs in more than twenty countries in both Hemispheres. In the Northern Hemisphere, a minor variation is attributed to the species, whereas larger morphological and chemical variations have been reported in specimens from the Southern Hemisphere. Six P. hookeri DNA sequences are available in GenBank, and only one (from Australia) is associated with a published morphological description. In this study, we performed a … Read more...

Kitaura M.J., Torres J.-M., Scur M.C., Lorenz A.P. & Faria R.R. (2022): New species and new records of Peltula (Lichinales, Ascomycota lichenized) from Mato Grosso do Sul, Brazil - Rodriguésia, 73: e02202020 [9 p.]

Peltula species occur in arid and semi-arid environments, with new species being regularly described worldwide. Lichen diversity is being studied in the diverse but poorly known Midwest region of Brazil, and new species and records are being proposed. In this paper, Peltula anthracina is proposed as new to science, and P. leptophylla and P. lingulata are reported as new records from Mato Grosso do Sul state. As it is a region highly threatened by the expansion of agricultural activities, the authors … Read more...

León C.A. & Benítez-Mora A. (2022): Key abiotic parameters for the management of the richness of bryolichenic communities in bogs of North Patagonia (Chile) - Acta Botanica Brasilica, 36: e2021abb0190 [11 p.]

Peatlands are ecosystems that play a special role in conserving biodiversity because they are refugia for unusual wetland-dependent species. Nevertheless, these ecosystems are threatened in southern South America by the overharvesting of Sphagnum moss, used in horticulture as substrate. Moreover, the biodiversity measurement as species richness has not been considered in management practices. Thus, our purpose was to study the bryophyte and lichen diversity and abiotic factors of Chiloé peatlands … Read more...

Popovici V., Musuc A.M., Matei E., Karampelas O., Ozon E.A., Cozaru G.C., Schröder V., Bucur L., Aricov L., Anastasescu M., Așchie M., Badea V., Lupuliasa D. & Gîrd C.E. (2022): ROS-induced DNA-damage and autophagy in oral squamous cell carcinoma by Usnea barbata oil extract—An in vitro study - International Journal of Molecular Sciences, 23(23): 14836 [33 p.]

Oxidative stress is associated with aging, cancers, and numerous metabolic and chronic disorders, and phenolic compounds are well known for their health-promoting role due to their free-radical scavenging activity. These phytochemicals could also exhibit pro-oxidant effects. Due to its bioactive phenolic secondary metabolites, Usnea barbata (L.) Weber ex. F.H. Wigg (U. barbata) displays anticancer and antioxidant activities and has been used as a phytomedicine for thousands of years. The present … Read more...

Jannah M., A`yun Q., Afifah N., Prasetya E. & Hariri M.R. (2022): Usnea in West Java: a potential source of bioactive secondary metabolites - Berkala Penelitian Hayati, 28: 26–31

Lichen is a symbiotic organism consisting of algae (photobionts) and fungi (mycobiont). In Indonesia, Usnea is the only genus of lichen that has been widely recognized and used by the local community for traditional medicine. It is locally known as kayu angin, rusuk angin, or janggot Kai. Furthermore, it produces lichen acid and other compounds as secondary metabolites that need investigation. Therefore, this study aimed to identify species and determine the secondary metabolites of Usnea in West … Read more...

Jüriado I., Degtjarenko P., Oja E. & Randlane T. (2022): A recent update in red-listing of Estonian lichens: threat status of 168 species was assessed for the first time - Folia Cryptogamica Estonica, 59: 69–81

The threat status of 168 lichenized species growing mostly on rocks or ground were assessed in 2022 for the first time in Estonia. The IUCN Red List system (categories and criteria) were used for that purpose. Most of the assessed taxa were microlichens (163), while five macrolichen species were also evaluated. Among the assessed species, 91 were assigned to the threat categories (Critically Endangered – CR, Endangered – EN and Vulnerable – VU), 17 species were assigned to the category Near … Read more...

Kossowska M. (2022): Hornfels rocks as a habitat for saxicolous lichen biota. A case study from the Sudety Mountains (SW Poland) - Folia Cryptogamica Estonica, 59: 35–41

The results of lichenological studies on hornfels outcrops in the Izerskie Mountains (Sudetes, SW Poland) are presented. This substrate is connected with the igneous intrusion into the country rocks and is characterized by a richer chemical and mineral composition than the surrounding rock bodies. In the six analyzed sites, a total of 48 saxicolous lichen species were found. Hornfels as a substrate for lichen vegetation is distinguished by the presence of lichens typical for rocks rich in metal compounds, … Read more...

Farkas E. & Muhoro A. (2022): Identification key to the lichen species of the parmelioid clade in Kenya - Lichenologist, 54(5): 299-318

Of the c. 900 lichen species known from Kenya, 178 belong to the parmelioid clade. Several of these parmelioid taxa require further revisionary studies. An identification key to the species of the parmelioid clade, based on updated nomenclature, is produced to support the practical work in collecting and selecting certain parmelioid lichens for further research. A new combination Parmotrema nyasense (C. W. Dodge) R. S. Egan comb. nov. in Egan et al., Bibliotheca Lichenologica110, 383 (2016) is published … Read more...
