Allen J.L., Calabria L.M., Braid H.E., Peterson E., Villella J., Sheehy S., Glew K., Graves J.M., Berim A., Bull R.D., Lymbery C.T. & McMullin R.T. (2022): Umbilicaria phaea var. coccinea: conservation status, variety rank, and secondary chemistry, Bryologist, 125(3): 387–405

Originally described from a single collection in northern California, Umbilicaria phaea var. coccinea has since been reported from additional sites in California, Oregon and Washington. Although relatively rare in all three states, there is currently no conservation status for U. phaea var. coccinea in California. Developing conservation strategies and status ranks requires a sound understanding of distribution, frequency, habitat requirements and taxonomic placement. Therefore, we evaluated … Read more...

Trobajo S., Fernández-Salegui A.B, Hurtado P., Terrón A. & Martínez I. (2022): Interspecific and intraspecific variability of water use traits in macrolichen species in a fragmented landscape along a climatic ecotone area, Fungal Biology, 126: 438–448

Water use traits in lichens are important attributes that determine the duration of hydration and metabolically active periods. In this study, the water holding capacity (WHC) and specific thallus mass (STM) were measured for seven macrolichen species (Parmelia sulcata, Parmelina tiliacea, Evernia prunastri, Ramalina farinacea, Lobaria pulmonaria, Lobarina scrobiculata and Nephroma resupinatum) from a Temperate-Mediterranean fragmented landscape. Twenty Quercus forests with different environmental conditions … Read more...

Potenza G., Gerardi G., Fascetti S. & Rosati L. (2022): Habitat fragmentation and lichen diversity in peri‐urban woodlands: A case study in the municipality of Potenza (southern Italy), Plants, 11(14): 1858 [12 p.]

The fragmentation of the natural habitat is a process that is exponentially increasing world‐ wide and represents one of the biggest threats to biological diversity. Habitat destruction and frag‐ mentation have a major impact on landscapes and may also affect ecosystems, populations, and spe‐ cies. The ongoing anthropogenic process can result in habitat loss for some species, habitat creation for others,reduced patch size, and increased distance between patches, which may lead to local … Read more...

Balčiūnaitienė A., Štreimikytė P., Puzerytė V., Viškelis J., Štreimikytė-Mockeliūnė Ž., Maželienė Ž., Sakalauskienė V. & Viškelis P. (2022): Antimicrobial activities against opportunistic pathogenic bacteria using green synthesized silver nanoparticles in plant and lichen enzyme-assisted extracts, Plants, 11: 1833 [14 p.]

Enzyme-assisted extraction is a valuable tool for mild and environmentally-friendly extraction conditions to release bioactive compounds and sugars, essential for silver nanoparticle (AgNP) green synthesis as capping and reducing agents. In this research, plant and fungal kingdoms were selected to obtain the enzyme-assisted extracts, using green synthesized AgNPs. For the synthesis, pseudo-cereal Fagopyrum esculentum (F. esculentum) and lichen Certaria islandica (C. islandica) extracts were used … Read more...

Zhang T., Zhang X., Yang Q. & Wei X. (2022): Hidden species diversity was explored in two genera of catapyrenioid lichens (Verrucariaceae, Ascomycota) from the deserts of China, Journal of Fungi, 8(7): 729 [17 p.]

Verrucariaceae is the third-largest lichen family with high species diversity. However, this diversity has not been well-explored in China. We carried out a wide-scale field investigation in the arid and semi-arid regions of Northwest China from 2017 to 2021. A large number of lichen groups, especially those commonly distributed in deserts, were collected. Based on molecular phylogeny using ITS and nuLSU sequences by Bayesian and maximum likelihood analyses, combining morphological characters, … Read more...

Mohammadi M., Zambare V., Suntres Z. & Christopher L. (2022): Isolation, characterization, and breast cancer cytotoxic activity of gyrophoric acid from the lichen Umbilicaria muhlenbergii, Processes, 10(7): 1361 [11 p.]

Lichens produce a large variety of secondary metabolites with diverse bioactivities, chemical structures, and physicochemical properties. For this reason, there is a growing interest in the use of lichen-derived bioactive molecules for drug discovery and development. Here, we report on the isolation, identification, and cytotoxic evaluation of gyrophoric acid (GA) from the lichen Umbilicaria muhlenbergii, a largely unexplored and scantly described lichen species. A simple purification protocol was … Read more...

Chrapusta-Srebrny E., Bialczyk J., Duchnik K. & Bober B. (2022): Metabolism of mycosporine-glutamicol in the lichen Cladonia arbuscula subsp. squarrosa under seasonal changes and elevated exposure to UV-B or PAR irradiation, Metabolites, 12(7): 632 [10 p.]

Cladonia arbuscula in its environmental niches is regularly affected by daily and annual variations in solar radiation. Mycosporine-glutamicol, Myc-Glu(OH), which it synthesizes, may act as a significant cellular UV-protector. Therefore, we studied this compound concentration in lichen thalli concerning seasonal changes and increased exposure to UV-B and photosynthetically active radiation (PAR) with/without simultaneous CO2 deprivation. Myc-Glu(OH) occurred year-round and exhibited a strong … Read more...

McCune B. & Conway S.N. (2022): Two new species, Hypogymnia tuckerae and H. discopruina (Parmeliaceae), from North America and China, Bryologist, 125(3): 406–417

Hypogymnia tuckerae is a newly described sorediate lichenized fungus currently known from three sites in the Cascade Range in Oregon, three sites in northern California, and one site in the Blue Mountains of northeastern Oregon. Although we have known a few of these anomalous sorediate specimens for many years, taxonomic action was stymied by possibilities that they were rare sorediate morphs of a normally fertile species, H. wilfiana, or a rare chemotype of a normally sorediate lichen, H. oceanica. … Read more...
