Pyatt F.B. (1976): Lichen ecology of metal spoil tips: effects of metal ions on ascospore viability, Bryologist, 79: 172-179

In the Tamar Valley area of southwest England are a number of metal spoil tips produced during the late 19th and early 20th century. These tips are an accumulation of materials from mining activity and metal extraction. Such tips frequently contain high quantities of metal ions but often in too low a concentration to be commercially exploitable. The ecology of these often unstable and toxic substrata is discussed with special emphasis on lichen distribution. Observations are presented concerning … Read more...

Maass W.S.G. (1975): Lichen substances VII. Identification of orsellinate derivatives from Lobaria linita, Bryologist, 78: 178-182

Tenuiorin, methyl gyrophorate (pseudocyphellarin) and methyl evernate were isolated from Lobaria linita. In addition, evidence (two-directional thin layer chromatography) was obtained for the presence of methyl lecanorate and methyl orsellinate, as well as of their respective parent compounds 4-0-methylgyrophoric acid, gyrophoric acid, evernic acid, lecanoric acid and orsel- linic acid in the same lichen.
