Asher O.A., Howieson J. & Lendemer J.C. (2023): A new perspective on the macrolichen genus Platismatia (Parmeliaceae, Ascomycota) based on molecular and phenotypic data, Bryologist, 126(1): 1–18

Lichens in the genus Platismatia are common, widespread and were some of the first to be studied by Western taxonomists. However, few molecular phylogenetic studies of Platismatia have been published to date. We present an expanded phylogeny of Platismatia inferred from 60 newly generated ITS sequences and 28 existing publicly available sequences. The new phylogeny confirms the delimitation of P. wheeleri as monophyletic and distinct from the widespread P. glauca, the latter of which was recovered … Read more...

Wright K., Berghe I.V., Sahramaa J. & Suomela J.A. (2023): Colorants detected by HPLC-PDA in textiles from 13th century Lieto Ristinpelto, Finland, Heritage, 6(2): 1209–1226

Organic colorants of textiles found in the female burial of Lieto Ristinpelto, SW Finland, were analyzed by HPLC-PDA. The textiles’ visible colors varied from different brownish shades to blueish, greenish, and reddish hues. The aim of the chromatographic analysis was to deepen the current understandings of the dyes used in Finland at the transition between the 12th and 13th centuries AD, i.e., at the beginning of the local Medieval period, and to contribute important new information about dyes … Read more...

Kello M., Goga M., Kotorova K., Sebova D., Frenak R., Tkacikova L. & Mojzis J. (2023): Screening evaluation of antiproliferative, antimicrobial and antioxidant activity of lichen extracts and secondary metabolites in vitro, Plants, 12(3): 611 [14 p.]

Lichen metabolites represent a wide range of substances with a variety of biological effects. The present study was designed to analyze the potential antiproliferative, antimicrobial and antioxidative effects of several extracts from lichens (Pseudevernia furfuracea, Lobaria pulmonaria, Cetraria islandica, Evernia prunastri, Stereocaulon tomentosum, Xanthoria elegans and Umbilicaria hirsuta) and their secondary metabolites (atranorin, physodic acid, evernic acid and gyrophoric acid). The crude extract, … Read more...

Sanders W.B. & de los Ríos A. (2023): Structure of foliicolous lichen thalli formed by some common lecanoralean taxa in subtropical leaf communities, Bryologist, 126(1): 35–44

Numerous distinct clades of lichen-forming fungi have independently specialized as foliicolous colonists of living leaves in the humid tropics and subtropics. Because of technical difficulties, the anatomy of their minute crustose thalli has not been compared in detail. In the present study, we applied SEM-BSE imaging to sectioned blocks of embedded thalli representing six lecanoralean taxa of foliicolous lichen-forming fungi with unicellular green algal partners. We compared our observations … Read more...

Condò C., Anfelli I., Forti L., Sabia C., Messi P. & Iseppi R. (2023): Lichens as a natural source of compounds active on microorganisms of human health interest, Applied Sciences, 13(3): 1976 [10 p.]

The antimicrobial properties of two lichen extracts (LC1 and LC2 solutions extracted in acetone and cyclohexane, respectively) were investigated against both Gram-positive and Gram-negative microorganisms through the agar well diffusion assay. Results displayed that both samples were similarly effective against all the indicator strains. The antimicrobial activity was maintained up to 30 days against Candida albicans ATCC 10231 with an inhibition zone of 38 mm and 37 mm for the LC1 and LC2 solutions … Read more...

Bannister J.M., Knight A. & Blanchon D. (2023): Reinstatement of Usnea capillacea Motyka (lichenized Ascomycota, Parmeliaceae) to the New Zealand lichenized mycobiota, Australasian Lichenology, 92: 8-13

The taxonomic histories of Usnea capillacea Motyka and U. articulata (L.) Hoffm. (Parmeliaceae) in New Zealand are discussed. Habitat preferences and molecular and morphological differences between the two species support reinstating Usnea capillacea to the New Zealand lichenized mycobiota for specimens currently referred to U. articulata.

Elix J.A. (2023): Two new species, a new combination and keys to the species of buellioid lichens (Caliciaceae, Ascomycota) in Antarctica, Australasian Lichenology, 92: 20-27

Amandinea norconiops Elix and Buellia tabarina Elix are described as new to science from Graham Land, Antarctica. In addition, the new combination Buellia cycloplaca (I.M.Lamb) Elix is made for Buellia russa var. cycloplaca I.M.Lamb, and a key is provided to the 46 species of buellioid lichens known from Antarctica.

Kantvilas G. (2023): The remarkable Lecidea hypersporella Stirt., Australasian Lichenology, 92: 3-7

Lecidea hypersporella Stirt., based on a type specimen from Tasmania, is described, illustrated and discussed. Known only from the original material, the taxonomic affinities of this species remain unknown. It is characterized by biatorine apothecia, polyspored asci approximating the Porpidia-type and simple, hyaline ascospores. Read more...
