Pyrczak-Felczykowska A., Reekie T.A., Jąkalski M., Hać A., Malinowska M., Pawlik A., Ryś K., Guzow-Krzemińska B. & Herman-Antosiewicz A. (2022): The isoxazole derivative of usnic acid induces an ER stress response in breast cancer cells that leads to paraptosis-like cell death - International Journal of Molecular Science, 23: 1802 [21 p.]

Derivatives of usnic acid (UA), a secondary metabolite from lichens, were synthesized to improve its anticancer activity and selectivity. Recently we reported the synthesis and activity of an UA isoxazole derivative, named 2b, against cancer cells of different origins. Herein, the molecular mechanisms underlying its activity and efficacy in vivo were tested. The viability of breast cancer or normal cells has been tested using an MTT assay. Cell and organelle morphology was analyzed using … Read more...

Cichowski D., Sutherland G.D., McNay R.S. & Sulyma R. (2022): Direct and indirect effects of habitat disturbances on caribou terrestrial forage lichens in montane forests of British Columbia - Forests, 13: 251 [27 p.]

Cumulative effects of increased forest harvesting, mountain pine beetle (Dendroctonus ponderosae; MPB) outbreaks, and wildfire in low-elevation lodgepole pine (Pinus contorta) forests could limit long-term winter habitat supply for the northern group of southern mountain caribou (Rangifer tarandus). In a 17 year longitudinal study of vegetation remeasurements at eight sites in north-central and west-central British Columbia (BC), we assessed responses of terrestrial caribou forage lichen abundances … Read more...

Albornoz L., Torres-Benítez A., Moreno-Palacios M., Simirgiotis M.J., Montoya-Serrano S.A., Sepulveda B., Stashenko E., García-Beltrán O. & Areche C. (2022): Phylogenetic studies and metabolite analysis of Sticta species from Colombia and Chile by ultra-high performance liquid chromatography-high resolution-Q-orbitrap-mass spectrometry - Metabolites, 12: 156 [16 p.]

Eleven species of lichens of the genus Sticta, ten of which were collected in Colombia (S. pseudosylvatica S. luteocyphellata S. cf. andina S. cf. hypoglabra, S. cordillerana, S. cf. gyalocarpa S. leucoblepharis, S. parahumboldtii S. impressula, S. ocaniensis) and one collected in Chile (S. lineariloba), were analyzed for the first time using hyphenated liquid chromatography with high-resolution mass spectrometry. In the metabolomic analysis, a total of 189 peaks were tentatively detected; the analyses … Read more...

Bartemucci P., Lilles E. & Gauslaa Y. (2022): Silvicultural strategies for lichen conservation: smaller gaps and shorter distances to edges promote recolonization - Ecosphere, 13(1): e3898 [20 p.]

Conservation of epiphytic lichens in managed forest landscapes relies on understanding limitations to their dispersal and establishment after harvesting. A hot spot for cephalo- and cyanolichens, the Kispiox inland temperate rainforest of British Columbia, Canada, is an example of where forest managers seek silviculture options that allow for forest harvesting to continue, while also conserving threatened species. To characterize colonization of these lichens (including the nationally threatened … Read more...

Elvebakk A. (2022): Psoroma femsjonense (Fr.) Trevis., a misunderstood species possibly extinct from Europe - Graphis Scripta, 34(2): 22–35

Psoroma femsjonense, long considered to be a synonym of P. hypnorum, is shown here to represent a distinct, misunderstood species. The collections seen are from the lowlands of southern Sweden, Denmark, Germany, the Czech Republic, and France. In these areas, the species has not been collected since 1945 and may prove to be regionally extinct from these countries. However, a report indicates that the species has recently been collected in high-altitude steppes in Anatolia of NE Turkey. Psoroma … Read more...

Davydov E.A. (2022): Umbilicaria platyrhiza—a new Mediterranean endemic species of the subgenus Papillophora (Umbilicariaceae, lichenized Ascomycota) - Phytotaxa, 533(2): 143–148

Umbilicaria platyrhiza Davydov sp. nov. is described within the Umbilicaria crustulosa – U. spodochroa species complex and illustrated. The new species resembles Umbilicaria crustulosa phenotypically, but is distinct by apothecia with a single gyrus of sterile tissue, grey-brown to black lower surface with flattened to strap-like rhizinomorphs, and by producing umbilicaric (vs. crustinic) acid. Umbilicaria platyrhiza inhabits silicate rocks at low elevations in the Mediterranean region of … Read more...

Kalb K. (2022): The lichen genus Catillochroma (Ascomycota, Ramalinaceae). Three new species and eight new combinations - Archive for Lichenology, 30: 1–14

Three new species of Catillochroma are described, viz. C. danfordianum Kalb and C. maree- baense Kalb, both from Queensland, Australia, and C. phayapipakianum Kalb from Chiang Rai Province, Thailand. Eight species are transferred to Catillochroma, viz. C. alleniae, C. alligatorense, C. beechingii, C. bicoloratum, C. coralloideum, C. flavosorediatum, C. hainanese and C. yunnanense. Habit photographs of the new and some other species, mentioned in the text are provided. Read more...

Aptroot A., de Souza M.F., Cáceres M.E.S, dos Santos L.A. & Spielmann A.A. (2022): New lichen records from Brazil - Archive for Lichenology, 31: 1–51

Based on recent records, 89 lichen species are reported as new to Brazil. For the genera Ancistrosporella, Jamesiella, Lambiella, Paulia, Polyblastia, Porocyphus, and Trimmatothele, it is the first time they are reported from Brazil. Many more, in total 523 species, are newly reported from individual states. Read more...

Knudsen K., Kocourková J. & Hodková E. (2022): Four species from New Mexico and Europe (Acarosporaceae) - Archive for Lichenology, 32: 1–10

The lichenicolous fungus Sarcogyne bicolor H. Magn. was recovered as an Acarospora and is given the replacement name, Acarospora destructans. It is reported new from New Mexico. Two new species of Acarospora are described from New Mexico, Acarospora eganiana and A. worthingtoniana. A form or variety of A. glaucocarpa is treated as a species, Sarcogyne melaniza, an apparently rare taxa in Europe. Keywords: Chihuahuan Desert, pathogenic lichenicolous fungi, species based on a single specimen. Read more...

Xie C.-M., Wang L.-S., Zhao Z.-T., Zhang Y.-Y., Wang X.-Y. & Zhang L.-L. (2022): Revision of Immersaria and a new lecanorine genus in Lecideaceae (lichenised Ascomycota, Lecanoromycetes) - MycoKeys, 87: 99–132

The species Immersaria cupreoatra has been included in Bellemerea. This caused us to reconsider the relationships between Bellemerea and the lecanorine species of Immersaria and to question the monophyly of Immersaria. Amongst 25 genera of the family Lecideaceae, most have lecideine apothecia, the exceptions being Bellemerea and Koerberiella, which have lecanorine apothecia. According to previous classifications, Immersaria included species with both lecanorine and lecideine apothecia. A five-loci … Read more...
