In this contribution we evaluate the production dynamics of epigeic sporocarps in saprophytic macromycetes growing in submountain beech monocultures. The studied research plots have been exposed to different immission load. On all three plots, we have determined a total number of 121 macromycetes species, 70 of them were involved into the evaluation of the biomass production. The species with the highest biomass production were: on the Research monitoring plot (RMP) Žiar nad Hronom: Marasmius rotula, Rhodocollybia butyracea f. asema, Clitocybe brumalis, Agrocybe praecox; on the Permanent research plot (PRP) Jalná: Strobilomyces strobilaceus, Hypholoma fasciculare, Clitocybe nebularis, Xerocomus chrysenteron; on the Experimental and ecological stationary (EES) Kováčová: Lycoperdon pyriforme, Lactarius piperatus, Clitocybe nebularis, Hygrophorus eburneus. We have recorded an increasing trend in biomass production in ectomycorrhizal macromycetes from the most loaded RMP Žiar nad Hronom to the lowest loaded plot EES Kováčová. At the same time, we have found an increase in sporocarp biomass of saprophytic macromycetes and simultaneously the lowest occurrence of ectomycorrhizal ones on the plot RMP Žiar nad Hronom. Relatively low values of the sporocarp biomass production on all three plots were caused by unfavourable microclimatic conditions during the study period and poor species composition of phytocoenoses in beech monocultures.
