Tree species preference of wood-inhabiting fungal OTUs and diversity (α-, β-and γ-diversity) detected for different tree species. Tree species preference is indicated by the R statistics from analysis of similarity (ANOSIM) based on the presence–absence data and Jaccard distance measure (R=0–0.24, no separation to barely separated (green); R⩾0.25–0.75, separation with different degrees of overlap (yellow); R>0.75–1, well separated to complete separation (red); significant P-values (P<0.05) are given in bold and are based on 9999 permutations and Bonferroni corrections in all cases). Different letters indicate significant differences (P<0.05) according to Kruskal–Wallis test combined with Mann–Whitney U-test of average R statistics among different wood type combinations (broadleaf and broadleaf=blue, n=21; broadleaf and coniferous=gray, n=28; coniferous and coniferous=black, n=6) and average fungal richness (Ascomycota (Asco) richness per sample (mean±s.e., n=27); Basidiomycota (Basi) richness per sample (mean±s.e., n=27); total richness per sample (mean±s.e., n=27)). Other fungi=Zygomycota, Chytridiomycota and unidentified fungi.
