Abstract Purpose Wood-inhabiting fungi play an important role in wood decomposition, and their community characteristics are influenced by both inherent wood nutrients and external nutrient inputs. However, how inherent nutrients from tree taxonomic groups interact with external nutrient inputs to influence fungal community characteristics remains unclear.Methods Here, we conducted a three-year field experiment in subtropical forest with eight tree species under four nutrient additions (no addition, nitrogen (N) addition, phosphorus (P) addition, and combined N and P addition), and investigated the effects of N and P additions on fungal communities in both overall wood and wood from different tree taxonomic groups (angiosperms and gymnosperms).Results Results showed that P addition had a stronger impact than N addition on fungal community structure, network complexity, and interaction strength between fungal species in overall wood. Considering tree taxonomic groups, fungal community structure in angiosperms was strongly affected by N addition, while in gymnosperms, it was predominantly affected by P addition. N addition significantly increased Ascomycota abundance, fungal diversity and network complexity in angiosperms, while P addition significantly decreased Ascomycota abundance, pathogenic fungi abundance, fungal diversity and network complexity in gymnosperms. These divergent responses of fungal communities were primarily driven by nutrient-induced changes in community’s demand for carbon (C) and nutrients, with angiosperms increasing fungal demand for wood C and gymnosperms decreasing fungal demand for wood P.Conclusion Our results highlight the key role of tree taxonomic groups in regulating the responses of wood-inhabiting fungal communities to nutrient additions through shifts in microbial nutrient demands.
