The phycobiliprotein pigments in the thallus and cephalodia of the 23 species (74 specimens) of lichens of the genus Peltigera from different latitudes and various ecological niches were studied. In the investigated species of the genus Peltigera C-phycoerythrin, C-phycocyanin and four types of allophycocyanin (allophycocyanin, allophycocyanin II, allophycocyanin B and allophycocyanin 680) were found. Only in the thallus of the Peltigera canina (collected in Illinois Saline, USA) C-phycocyanin was predominant (50%). Whereas in the remaining species allophycocyanins were found to predominate (35.6-71.7%). The total content of phycobiliprotein pigments ranged between 0.142 (Peltigera canina, collected in Mongolia) and 3.688 mg g-1 dry weight (Peltigera horizontalis, collected in Ireland). The biggest total content of phycobiliproteins pigments and the value of CPC/CPE ratio was observed in some species in autumn and winter and when the red light was used.
