Ecological diversity of some resource medicinal mushrooms of the genus Pleurotus in the Novosibirsk Region

In this paper the authors reveal features of substrate specialization and habitats distribution of the biotechnologically valuable medicinal resource species of Pleurotus pulmonarius mushrooms in the Novosibirsk Region. The authors show the distribution of the species on deciduous and coniferous tree species, in connection with substrate specificity, distribution in habitats and seasonal features of fructification formation. The studied species is confined mainly to deciduous trees; it was noted only once on Abies sibirica. In general, P. pulmonarius was recorded on 5 species of deciduous trees, most of the samples were collected on Betula pendula and Populus tremula. Less often the fungus is found on Sorbus sibirica, Populus sp., Acer negundo, Tilia cordata, Salix alba. P. pulmonarius develops in zonal small-leaved and mixed forests most often, it is rarely found in river floodplains and near-river communities. Quite often the fungus is found in artificial plantations, where it is one of the most common wood-decay fungi of anthropogenic habitats. Fructification of P. pulmonarius in the Novosibirsk Region occurs from May to October, its peak activity is in late summer – early fall (August-September).
