Neoplaca mirabilis , a new genus and a new epigaeic species containing naphthopyrans from the family Teloschistaceae
Abstract The production of anthraquinones is a major characteristic of most species in the Teloschistaceae . Other secondary metabolites are quite rare in this family, but some species are known to produce depsides, depsidones, xanthones and usnic acid. A new monotypic genus, Neoplaca , with a new s...
