During our project we investigate the effect of tree diversity on the production, species richness and nutritional values of the mushrooms. We collected all soil macrofungi from plots of non-identical tree biodiversity (1- and 3 species mixtures) to compare their production, species richness and nutritional values in different “tree diversity conditions”. This data sheet contains information about the production (macrofungi sporocarps biomass [g]) and diversity (no of macrofungi species) in diffrent plots.

Sampling took place in every 1- or 3-species plot (VIP plots). First, mushrooms were collected at the entire plots (30x30m), extended with a 2,5m-wide stripe of land around (35mx35m). Mushrooms from each plot were collected to separate baskets. Then, we: 1) determined mushrooms species to the lowest possible level 2) weighed fresh mass of each species from every plot separately with 0,1 g accuracy 3) dried the samples in 50℃ for 18h (longer if needed) 4) weighed samples with 0.1 g accuracy 5) took samples of edible mushrooms present in more than 40% of plots to a laboratory, to analyze their content od aminoacids.
