The Phycobiliprotein pigments in the thallus of 19 species (23 specimens) from genera Leptogium from different altitudes and various ecological niches were studied. In all the lichens species studies such phycobiliprotein pigments as C- phycoerithrin, C-phycocyanin and allophycocyanin were found. In thallus of Leptogium denticulatum (collected in New Mexico State, USA), Leptogium mandonii and Leptogium meuziesii (both species collected in Andes, Venezuela) such rare phycobiliproteins as allophycocyanin I, allophycocyanin B and phycoerythrocyanin were found. In thallus of Leptogium denticulatum, Leptogium saturninum (collected in Alaska, Canada), Leptogium mandonii and Leptogium phyllocarpum C-phycocyanin was the predominant phycobiliprotein, whereas in thallus of remaining species allophycocyanins were predominant. The total content of phycobiliproteins in the studied material ranged from 0.162 (Leptogium marginellum) to 1.051 mg g-1 dry weight (Leptogium cyanescens). In all investigated lichen species the presence of phytochrome was observed.
