Petersson L., Lariviere D., Holmström E., Fritz Ö. & Felton A. (2022): Conifer tree species and age as drivers of epiphytic lichen communities in northern European production forests, Lichenologist, 54: 213-225

The epiphytic lichen species richness and community composition was compared for 600 living trees distributed within the interior of 60 Scots pine and Norway spruce monoculture stands in southern Sweden. A higher species richness, and more unique species, was found on trees of Scots pine than of Norway spruce, and distinctive communities were associated with the two tree species. Lichen species com- position also shifted between the 30-, 55- and 80-year-old stands, although there was no significant … Read more...

Rada P., Halda J.P., Holuša J., Maliňáková K. & Horák J. (2022): Urban fruit orchards: Biodiversity and management restoration effects in the context of land use, Urban Forestry & Urban Greening, 75: 127686

Urban areas have increased greatly in recent decades, which has resulted in habitat loss. However, the promotion of urban green spaces could have a profound effect on biodiversity. Traditional fruit orchards are an important land-use type with the potential to host myriad organisms. Our goal was to determine the most important factors that influence orchard biodiversity in the million city of Prague (the capital of the Czech Republic). We used a multitaxon approach to evaluate the effect of orchard … Read more...

Garrido-Benavent I., Chiva S., Bordenave C. D., Molins A. & Barreno E. (2022): Trebouxia maresiae sp. nov. (Trebouxiophyceae, Chlorophyta), a new lichenized species of microalga found in coastal environments, Cryptogamie, Algologie, 43(9): 135–145

Coccoid microalgae of the genus Trebouxia Puymaly are by far the most prevalent among the various species involved in lichen symbioses. However, their taxonomic knowledge is rather scarce compared to that of lichenized fungi. In the present work, a taxonomic study integrating diverse techniques (phylogenetics, light, confocal and transmission electron microscopies) is carried out to describe Trebouxia maresiae Garrido-Benavent, Chiva & Barreno, sp. nov. This species widely associates with the … Read more...

Mishra G.K., Nayaka S., Upreti D.K., Kondratyuk S.Y., Thell A. & Kärnefelt I. (2022): Cetrarioid lichens from India revised, including Nephromopsis awasthii sp. nov. and new records, Mycotaxon, 137: 283–334

Morpho-taxonomic studies of cetrarioid lichens from India recorded 46 species representing Cetraria, Melanelia, Nephromopsis, and Platismatia. Nephromopsis awasthii is described as new to science; and Cetraria endochrysea, C. sinensis, Melanelia agnata, Nephromopsis ciliaris, N. morrisonicola, N. pseudocomplicata, N. pseudoweberi, N. rugosa, N. weii, and N. yunnanensis are reported for the first time from India. A key to all genera and species of cetrarioid lichens in India is provided together … Read more...

McMullin R.T. & Miadlikowska J. (2022): Two rare Peltigera species new to the Canadian Arctic, P. islandica and P. lyngei, Plant and Fungal Systematics, 67(1): 17–23

Peltigera islandica and P. lyngei are rarely reported lichens. Previously, P. islandica was known from British Columbia, Estonia, and Iceland, and P. lyngei from Amchitka Island (Alaska), Gough Island (South Atlantic), Iceland, Siberia and Svalbard. Both species are reported here for the first time from the Canadian Arctic and from the second localities in North America. Peltigera lyngei is also reported for the first time from Canada. The identities of these species are confirmed morphologically, … Read more...

Cometto A., Ametrano C.G. & Muggia L. (2022): Life on top: cryptoendolithic ascomycetes and microalgae isolated from over 6000 m altitude, Plant and Fungal Systematics, 67(1): 1–16

Rocks are among the oldest terrestrial niches hosting a multiplicity of life forms, of which diversity has been only partially uncovered. Endolithic metacommunities comprise all major groups of microorganisms, such as chemo-organotrophic, chemo-lithotrophic and phototrophic, represented by bacteria, microalgae and microfungi. Their diversity is often difficult to describe and may remain underestimated. Furthermore, knowledge about the diversity of microorganisms colonizing rocks in peculiar … Read more...

Fayyaz I., Kouser R., Afshan N.S., Niazi A.R., Zulfiqar R., Khalid A.N. & Kondratyuk S.Y. (2022): Iqbalia kashmirensis gen. et sp. nov. from Pakistan (Teloschistaceae, lichenized ascomycetes) based on multigene phylogeny, Mycological Progress, 21: 68 [15 p.]

The robust monophyletic branch having the highest level of bootstrap support in the phylogenetic tree of the Teloschistaceae, based on combined dataset of nrITS, 28S nrLSU DNA, and mtSSU sequences, which does not belong to any other earlier proposed genera of the subfamily Teloschistoideae, is described as new genus. The genus Iqbalia is characterized and differs from the closely related genus Nevilleilla by having discrete and compact/aggregated, rather not scattered areoles, without schizidia-like … Read more...

Daminova A.G., Rogov A.M., Rassabina A.E., Beckett R.P. & Minibayeva F.V. (2022): Effect of melanization on thallus microstructure in the lichen Lobaria pulmonaria, Journal of Fungi, 8(8): 791 [10 p.]

Lichens often grow in microhabitats where they experience severe abiotic stresses. Some species respond to high UV radiation by synthesizing dark brown melanic pigments in the upper cortex. However, unlike the melanized structures of non-lichenized fungi, the morphology of the melanic layer in lichens remains unstudied. Here, we analyzed the morphology, ultrastructure, and elemental composition of the melanized layer in UV-exposed thalli of the lichen Lobaria pulmonaria (L.) Hoffm. Using light microscopy, … Read more...

Zorrilla J.G., D’Addabbo T., Roscetto E., Varriale C., Catania M.R., Zonno M.C., Altomare C., Surico G., Nimis P.L. & Evidente A. (2022): Antibiotic and nematocidal metabolites from two lichen species collected on the Island of Lampedusa (Sicily), International Journal of Molecular Sciences, 23(15): 8471 [12 p.]

The antibiotic and nematocidal activities of extracts from two coastal lichen species collected on Lampedusa Island (Sicily), Ramalina implexa Nyl. and Roccella phycopsis Ach., were tested. Methyl orsellinate, orcinol, (+)-montagnetol, and for the first time 4-chlororcinol were isolated from Roccella phycopsis. (+)-Usnic acid was obtained from Ramalina implexa. The crude organic extract of both lichen species showed strong antibiotic activity against some bacterial species and nematocidal activity. … Read more...

Kawagoe H., Itioka T., Hyodo F., Iku A., Shimizu-kaya U. & Meleng P. (2022): Evidence in stable isotope ratios for lichen-feeding by Lithosiini moths from a tropical rainforest but not from a temperate forest, Entomological Science, 25: e12519 [10 p.]

Lithosiini (Lepidoptera: Erebidae: Arctiinae) is distinctive in having some species that feed on lichens, whereas the majority of moths feed on vascular plants. However, the larval diet of most Lithosiini species is poorly known. This study examines whether Lithosiini species, collected in a tropical rainforest of Borneo (nine species) and a temperate forest of Japan (eight species), feed on lichens as larvae, based on stable isotope analyses. As a result, the δ15N values for eight of nine Lithosiini … Read more...
