Аннотация:Basidiomycetous fungi Pleurotus pulmonarius and P.ostreatus are widely spread in forest biocoenoses in Central Russia. They are most popular cultivated species. These closely related species are very similar in morphology, in substrates' specificity, but at the same time they are reproductively isolated ones. Low temperature sensitivity of natural mushroom isolates and cultivated commercial strains were tested under laboratory conditions. In natural habitat, P. ostreatus isolates were shown to predominate under a fluctuation of day-time and night-time temperature. Nevertheless, under the laboratory conditions fruit bodies' production of P.ostreatus was not affected by low temperature treatment. On opposite, fructification of P. pulmonarius was shown to be stimulated only under constant temperature of 22-24°C. Divergence of populations of the closely related Pleurotus species is more likely based on adaptation to changeable temperature conditions in natural habitats, reproductive isolation being ahead of morphological and physiological divergence between the species.
