Monitoring of ectomycorrhizal fungi in the bilberry-sphagnum pine forest in the southern taiga of the Perm territory

The monitoring of agarics in the Perm Territory has been done since 1975 till the present time in the different types of forests (the southern taiga subzone). The research has been carried out by a stationary method (the test areas are 50x20 m) in 3 stages: I period - 1975-1977; II period - 1994-1996; Ш period - 2010-2012. Despite high humidity in the bilberry-sphagnum pine forest, mycorrhiza of Pinus sylvestris L. and Betula pubescens Ehrh. is well developed, mycorrhizal terminations are of complex structure. By the present time, 80 species and intraspecific taxa of agarics have been found in the bilberry-sphagnum pine forest, 45 of them (56.3 %) are ectomycorrhizal fungi. The mushrooms belong to 7 families and 12 genera. Families Cortinariaceae and Russulaceae prevail. The majority of species are in 4 genera: Cortinarius (41 species), Lactarius (6), Hebeloma (4), Russula (3). We have noted that biota of the mycorrhizal fungi has changed more than that of the higher plants (JI-II = 83, JII-III = 82, JI-III = 75). Jaccard index calculated by appearing mushrooms varies from 7 to 32. Mycorrhizal mushrooms are among dominant species in terms of their biomass and number. We have studied the connection between species diversity and productivity of agaricomycetes and the climate. We have found the negative impact of June rainfall on the > of ectomycorrhizal fungi (rs = -0.70).
