Absence of anthraquinone pigments is paraphyletic and a phylogenetically unreliable character in the Teloschistaceae

Original language description

It has been suggested that the absence of anthraquinones is not a synapomorphic character, but appears independently in unrelated lineages of Teloschistaceae. We analyzed ITS nrDNA regions in species of the genus Caloplaca and present evidence for five such examples: the Caloplaca cerina group, C. obscurella, the C. servitiana group, the C. xerica group and the C. variabilis group (Pyrenodesmia). In some cases, loss of anthraquinones is observed only in individuals within ordinarily pigmented populations, but sometimes the loss covers whole lineages containing one or more species. Both situations are observed in the C. servitiana group. Loss of anthraquinones is always followed by the synthesis of 'alternative' pigments (often Sedifolia-grey). In the specimens with anthraquinone-containing apothecia studied, these pigments are not visible in apothecial sections after dissolving anthraquinones in K. Fully unpigmented apothecia have not been observed. The Caloplaca xerica group is a newl
