van den Boom P.P.G., Brand A.M., Coppins B.J. & Sérusiaux E. (2018): A new Micarea species from western Europe, belonging in the Micarea denigrata group - Herzogia, 31: 385–389

A new species of Micarea, M. sambuci is described from western Europe. Though it was common in the Netherlands and also present in Belgium, Luxemburg, Germany, and Scotland, it could now be extinct. It differs from M. nitschkeana by the production of mesoconidia (2.7–4.1 × 1.1–1.5 μm) and complete absence of micro- and macroconidia. Key words: Lichenized ascomycete, Lecanorales, taxonomy.

Poulin J. (2018): A new methodology for the characterisation of natural dyes on museum objects using gas chromatography–mass spectrometry - Studies in Conservation, 63(1): 36–61

The derivatising agent m-(trifluoromethyl)phenyltrimethylammonium hydroxide (TMTFTH) has been employed for more than a decade at the Canadian Conservation Institute (CCI) to extract natural dyes from historical textiles and other dyed substrates. The alkaline reagent breaks the bonds between the colourants and the mordant ions or functional groups of the substrate, releasing the dye compounds into the extraction solution, and derivatises polar functionalities to produce compounds that are amenable … Read more...

Sueoka Y., Sakakibara M., Sano S. & Yamamoto Y. (2016): A new method of environmental assessment and monitoring of Cu, Zn, As, and Pb pollution in surface soil using terricolous fruticose lichens - Environments, 3(4): 35 [13 p.]

Levels of trace element pollution in surface soil can be estimated using soil analyses and leaching tests. These methods may reveal different results due to the effect of soil properties, such as grain size and mineral composition, on elemental availability. Therefore, this study advocates an alternative method for monitoring and assessment of trace element pollution in surface soil using terricolous fruticose lichens. Lichens growing at abandoned mine sites and unpolluted areas in southwest … Read more...

Silberstein L., Siegel S.M., Keller P., Siegel B.Z. & Galun M. (1990): A new method for the extraction of ATP from lichens - Bibliotheca Lichenologica, 38: 411-418

In the present study we describe a new method for ATP extraction from lichens. The advantage of this method is that the extraction is much more efficient and more convenient than other methods used. Changes of ATP levels are suggested as indicators for the effect of air pollution on lichens. Read more...
