Ja. Elix et Ht. Lumbsch, THE CHEMISTRY OF SOME SPECIES OF LECANORA-SENSU-STRICTO (LECANORALES,LICHENIZED ASCOMYCOTINA), Mycotaxon, 59, 1996, pp. 309-317
The chemistry of 27 species belonging to the Lecanora subfusca group (
i.e. Lecanora s.str.) has been investigated, in most cases for the fir
st time. 5-Chlorolichexanthone, isoplacodiolic acid, isonotatic acid,
6-O-methylarthothelin, 4-O-methylhypoprotocetraric acid, 2'-O-methylst
enosporic acid and zeorinone are recorded for the first time in Lecano
ra s.str. L. flavidocarnea Vainio is reduced to synonymy with L. helva
Stizenb. and L. rubrofusca B. de Lead. with L. puniceofusca Bagl.
