Aberhart D.J., Overton K.H. & Huneck S. (1969): Studies on lichen substances. Part LXII. Aromatic constituents of the lichen Roccella fuciformis DC. A revised structure for lepraric acid - J. Chem. Soc., sect. C , 1969: 704-707

Three aromatic constituents have been isolated from the lichen Roccella fuciformis: lepraric acid (1; R = H), the chromone (2), and ethyl orsellinate. Chemical and spectroscopic evidence is presented for the revised structure (1; R = H) of lepraric acid. Read more...

Abrego N., Norros V., Halme P., Somervuo P., Ali-Kovero H. & Ovaskainen O. (2018): Give me a sample of air and I will tell which species are found from your region: Molecular identification of fungi from airborne spore samples - Molecular Ecology Resources, 18: 511–524

Fungi are a megadiverse group of organisms, they play major roles in ecosystem functioning and are important for human health, food production and nature conservation. Our knowledge on fungal diversity and fungal ecology is however still very limited, in part because surveying and identifying fungi is time demanding and requires expert knowledge. We present a method that allows anyone to generate a list of fungal species likely to occur in a region of interest, with minimal effort and without requiring … Read more...

Aceto M., Arrais A., Marsano F., Agostino A., Fenoglio G., Idone A. & Gulmini M. (2015): A diagnostic study on folium and orchil dyes with non-invasive and micro-destructive methods - Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 142: 159-168

Folium and orchil are dyes of vegetal origin. Folium is obtained from Chrozophora tinctoria (L.) A. Juss., whereas orchil is obtained from Roccella and other genera of lichens. These dyes were used in the past to impart purple hue to paintings and textiles as substitutes for the more prised Tyrian purple dye, obtained from shellfish. Despite several citations in ancient technical treatises dating back at least to the Greek-Roman age, the identification of these dyes in artworks is rare. In the case … Read more...

Aceto M., Calà E., Agostino A., Fenoglio G., Idone A., Porter C. & Gulmini M. (2017): On the identification of folium and orchil on illuminated manuscripts - Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 171: 461–469

The identification of the two purple dyes folium and orchil has rarely been reported in the analysis of painted artworks, especially when analysing illuminated manuscripts. This is not consistent with the fact that ancient literary sources suggested their use as substitutes for the more expensive Tyrian purple dye. By employing non-invasive spectroscopic techniques, the present work demonstrates that these dyes were actually widely used in the production of ancient manuscripts. By employing UV–visible … Read more...

Ackerman R.E. (1964): Lichens and the patination of chert in Alaska - American Antiquity, 29(3): 386-387

The exposed surfaces of stone artifacts from the Security Cove site, Alaska, were altered by the mechanical/chemical activity of crustose lichens. This factor should be considered in patination studies carried out in regions where lichens are known to occur. The activity of lichens and the resultant effect on artifact surfaces is discussed and illustrated in two figures. Read more...
