The phycobiliprotein pigments in the thallus of 21 species (22 specimens) from genera Collema from different altitude were studied. In all lichen species studied phycobiliprotein pigments as C-phycoerythrin, C-phycocyanin and allophyco-cyanin were found. In thallus of some species rare phycobiliproteins such as allophycocyanin I, allophycocyanin B and phycoerythrocyanin were found. In the thallus of five species, C-phycocyanin was predominant (41.2-52.8%). In the remaining species, allophycocyanins were  found  to  predominate  (48.4-57.3%).  The  total  content  of  phycobiliproteins  in  the  studied  material  ranged  from  0.184  (Collema rugosum)  to  1.982 mg g^-1 dry weight (Collema subnigrescens). In some species of lichens the presence of phytochrome was observed.
