Abstract
The results of 40-year monitoring of agarics in four types of pine forests in the Perm Krai are summed up (southern taiga subzone). We have learnt that species number in the pine forests varies from 80 (sphagnum pine forest) to 194 (lichen pine forest). We have shown the changes in species composition and the increase of species diversity in each period of the monitoring. We have analyzed ecological structure and defined species that are dominant by their number and biomass. Despite the changes of the species composition, ecological groups ratio in each forest type remains almost the same. The common feature is that mycorrhizal fungi prevail in the pine forests by species number (55.5-61.2 % of all the species number in the cenosis), as well as by yield (52 % of the total number and 94 % of total biomass). We have studied connection between species diversity and productivity of agaricomycetes and the climate. We have found that July rainfall is favorable for the “fruit bearing” of agarics in the pine forest with moderate humidity in August ( rs = 0.73). In swampy cenoses June rainfall, on the contrary, has negative impact ( rs = -0.70).
