Micheletti A.C., Honda N.K., Ravaglia L.M., Matayoshi T. & Spielmann A.A. (2021): Antibacterial potencial of 12 Lichen species, Anais da Academia Brasileira de Ciências, 93(4): e20191194 [11 p.]

Resistant bacterial infections are a major public health problem worldwide, which entails the need to search for new therapeutic agents. In this context, lichens stand out, provided that they are producers of structurally diverse compounds that have attractive biological properties, including antimicrobial activity. Thus, extracts of 12 lichen species were prepared and their potential to inhibit the growth of 5 bacterial strains was evaluated in this work. The chemical compositions of these … Read more...

Wirth V. (2021): Neue und bemerkenswerte Funde von Flechten und flechtenbewohnenden Pilzen in Süddeutschland und Umgebung, Carolinea, 79: 5–17

New and noteworthy records of lichens and lichenicolous fungi from southern Germany and adjacent regions. [in German with English abstract: ] Occurrences and habitat conditions of 40 rare or ecologically noteworthy species are dealt with, e. g. of Caloplaca squamuloisidiata, Candelariella boleana, Stereocaulon leucophaeopsis, Strigula ziziphi and Toniniopsis dissimilis, which were recorded recently as new to France or Germany. Central European records of the newly differentiated species … Read more...

Schmitz D., Villa P.M., Michel R.F.M., Putzke J., Pereira A.B. & Schaefer C.E.G.R. (2021): Species composition, diversity and coverage pattern of associated communities of mosses-lichens along a pedoenvironmental gradient in Maritime Antarctica, Anais da Academia Brasileira de Ciências, 94(Suppl.1): e20200094 [17 p.]

Maritime Antarctica is one of the major terrestrial ecosystems dominated by lichens and mosses, which represent important ecological indicators. Thus, we aimed to evaluate the changes in associated communities of mosses-lichens diversity and coverage along a pedoenvironmental gradient on Half Moon Island, Maritime Antarctica. We focused on how patterns in associated communities of mosses-lichens species diversity (richness, species composition and beta diversity) and coverage are associated … Read more...

Darmostuk V.V. (2021): Lichenicolous fungi on Verrucaria s. lat. in Ukraine with the description of Zwackhiomyces khodosovtsevii sp. nov. and a key to the lichenicolous fungi on Verrucaria s. lat., Botanica Serbica, 45(2): 293–301

A revision of lichenicolous fungi on Verrucaria s. lat. in Ukraine is provided. As a result, 12 species of lichenicolous fungi on Verrucaria s. lat. are reported from Ukraine. Among them, Zwackhiomyces khodosovtsevii on Verrucaria cf. nigrescens is described as new to science and Lichenopeltella coppinsii on V. muralis, Stigmidium marinum on V. mucosa as well as S. rivulorum on V. dolosa, are newly reported to Ukraine. Ten species are reported from xerotic terrestrial habitats mainly from Southern … Read more...

Kim T.K., Hong J.-M., Kim K.H., Han S.J., Kim I.-C., Oh H. & Yim J.H. (2021): Potential of ramalin and its derivatives for the treatment of Alzheimer’s disease, Molecules, 26(21): 6445 [12 p.]

The pathogenesis of Alzheimer’s disease (AD) is still unclear, and presently there is no cure for the disease that can be used for its treatment or to stop its progression. Here, we investigated the therapeutic potential of ramalin (isolated from the Antarctic lichen, Ramalina terebrata), which exhibits various physiological activities, in AD. Specifically, derivatives were synthesized based on the structure of ramalin, which has a strong antioxidant effect, BACE-1 inhibition activity, and anti-inflammatory … Read more...

Roux C. (2021): Du novaj specioj de Acarosporaceae el Francio. Deux espèces nouvelles d’Acarosporaceae de France, Bulletin de la Société Linnéenne de Provence, 72: 31–46

[bilingual in Esperanto and French; diagnoses in Esperentoo and Latin] Acarospora poumaratii Cl. Roux sp. nov. diffère d’A. germanica surtout par ses apothécies à rebord nul ou mince, son hyménium moins haut, ses paraphysoïdes plus larges et son écologie (étage mésoméditerranéen inférieur). Clauzade et Roux (1981) l’avaient attribué à A. suzae var. tyroliensis. Thelocarpella wirthii Cl. Roux sp. nov. diffère de T. gordensis (la seule autre espèce connue dans le genre) surtout … Read more...

Wirth V. (2021): Lichenologische Notizen aus dem linksrheinischen Berg- und Hügelland in Westdeutschland, Decheniana , 174: 63–91

[in German with English abstract: ] From 27 localities, extending from Palatinate Forest in the south to the Eifel in the north, species lists are given. On the whole they show a considerable species diversity. Reasons are: richness in rocky areas, geological diversity, climatic contrasts between cool-oceanic and xerothermal areas and habitats. Some subatlantic species are much more frequent than in the regions east of the Rhine valley. Noteworthy findings are Trapeliopsis wallrothii, Tremolecia … Read more...

Lendemer J.C. & Clark P. (2021): Between a rock and a hard place: Chrysothrix susquehannensis is more widespread in eastern North America than previously thought, Opuscula Philolichenum, 20: 81–87

Chrysothrix susquehannensis was originally described from vertical rocks faces at a single locality in southeastern Pennsylvania, U.S.A. Here we document new occurrences discovered as result of fieldwork and the revision of herbarium specimens. We show that C. susquehannensis, although rare, is widespread in the Appalachian Mountains of eastern North America, with a disjunction in New Mexico in southwestern North America. Read more...

Varga N., Lőkös L. & Farkas E. (2021): Annotated checklist of the lichenicolous fungi of Hungary, Diversity, 13(11): 557 [20 p.]

Knowledge of lichenicolous fungi is limited at a worldwide level and needs further basic information, as in the case of Central and Southern Europe. The literature sources for “Revised checklist of the Hungarian lichen-forming and lichenicolous fungi” by Lőkös and Farkas in 2009 contained 54 lichenicolous and other microfungi species of 38 genera. Due to recent field studies and microscopic work, the number of known species has increased to 104 lichenicolous species in 64 genera during the … Read more...

Zhurbenko M.P. (2021): Lichenochora sedelnikoviorum, a new species from the Russian Arctic with a synopsis of published additions to the Panarctic checklist of lichenicolous fungi, Opuscula Philolichenum, 20: 73–80

Lichenochora sedelnikoviorum, a lichenicolous ascomycete growing on Rostania ceranisca (Collemataceae), is described as new to science from the Arctic. The species is characterized by the absence of gall-induction, more or less exposed ascomata up to 300 μm in diameter, 4–8-spored asci, 70–110 × 10–14 μm, and (rarely 0–)1-septate ascospores, (20.5–)24.5–31.5(–37) × (4.5–)5.5–6.5(–7.5) μm. A list of additions to the Panarctic checklist of lichenicolous fungi, which now includes … Read more...
