The presence of P. primaurelia, P. biaurelia, P. triaurelia, and P. novaurelia of the P. aurelia complex was revealed in the studied region of Russia. RAPD-PCR fingerprints (band patterns) of newly identified P. novaurelia strains from Russia were compared to those characteristic for the other chosen European strains of the species. The strains revealed intraspecific polymorphism as several groups of genotypes confirming the existence of polymorphism within P. novaurelia.
