Specific features of the species composition of mycetobiont algae inhabiting the basidiocarps Cerrena unicolor, Stereum hirsutum, S. subtomentosum, Trichaptum abietinum, T. fuscoviolaceum, T.biforme in the pre-forest-steppe pine-birch and southern taiga spruce forests of the Middle Urals are considered. The identification of algae was carried out with direct microscopy of basidiocarp and using the method of storage cultures on agar medium 3N BBM. Most of the mycetobiont algae are found with direct microscopy of basidiocarp, less - in cultures. The first group is a physiologically active part of the mycetobiont communities that characterizes their actual biodiversity, and the second group is a potential one that is realized under certain specific conditions or a period of growing season. It is shown that the basis of mycetobiont communities (96 %) is unicellular and colonial coccoid, less often filamentous green algae. In their composition, there are no obligate mycetobionts and all this is known soil, lithophilic, epiphytic, algae, as well as photobionts of lichens. The mycetobiont communities associated with different species of fungi differ in the number of species (6-15) and in their composition: the composition of algae inhabiting the basidiocarp Trichaptum fuscoviolaceum and T.biforme, as well as the Stereum hirsutum and S. subtomentosum, is closest. The mycetobiont algae differ markedly in hostal specificity and plasticity. Some of them are found in basidiocarps of only one fungus, less often in basidiocarpas of all fungi ( Coenochloris signiensis, Interfilum terricola and Pseudococcomyxa simplex ), which indicates a selective ratio of mycetobiont algae to fungi. On average, from 4 to 6 species of algae inhabit one basidiocarp.
