During our project we investigated the effect of tree diversity on the productivity, species richness and nutritional value of mushrooms. We collected sporocarps of all soil dwelling macrofungi from 1- and 3-species tree mixtures to compare mushroom productivity, species richness and nutritional value in different “tree diversity levels”. This data sheet contains information about the productivity (sporocarp biomass [g]) and diversity (no of species) per plots.

Sampling took place in every 1- or 3-species plot (VIP plots). First, mushrooms were collected at the entire plots (40x48m), excluding the 4m-wide edge strip of the plot (eventual size - around 32x40m). Next, 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.
