Abstract

Two hundred and three specimens belonging to the genus Cetrelia from the Soviet Union and also 41 samples from other countries have been analysed by TLC. Eight species were determined in the Soviet Union. In addition two new species, C. orientalis and C. pseudocollata sp. nov. are described. Five morphotypes and six chemotypes have been recognized in the genus: their main characteristics are tabulated in a form that can be used for identification and a key is also included. Evolutionary relationships between the ‘primary’ and ‘secondary’ species related to ‘species-pairs’ are discussed.
