Conversion of diverse native forests to tree monocultures remains an ongoing, worldwide threat to biodiversity. Although the effects of forest conversion have been studied in a wide range of taxonomic groups, the effects on macrofungal communities remain poorly understood. We sampled macrofungal fruiting bodies in the National Forest of São Francisco de Paula in Southern Brazil over 12 months in four different forest habitats: native Araucaria angustifolia forest, A. angustifolia plantation, Pinus taeda or P. elliottii plantation, and Eucalyptus saligna plantation. The distribution of macrofungal species in different functional groups varied among habitats: the macrofungal species composition of the A. angustifolia plantation was more similar to that of the native forest, while the exotic Pinus or Eucalyptus plantations were less similar to the native forest. The conversion of native forest to exotic tree plantations reduced the number of macrofungal decomposer species, probably due to changes in substrate availability and quality. We conclude that fungal diversity and ecosystem functionality require the preservation of native, mature forests and suggest a shift of Brazilian forestry guidelines to encourage the plantations of native species instead of exotics.
