Fungi are the main agents of coarse woody debris decomposition in forest ecosystems. We examined the associations of environmental variables with fungal community structures in dead pine logs at 12 geographically distant sites using amplicon pyrosequencing of fungal ITS rDNA. A total of 575 operational taxonomic units (OTUs) were identified based on clustering at 97% similarity. Among the known fungal ecological groups, saprotrophic fungi generally showed highest frequency of occurrence and were positively associated with mean annual temperature (MAT) and log diameter. Wood decay fungi with unknown decay type were positively associated with pine wilt disease and negatively associated with log diameter. Ordination analysis of the 42 most prevalent OTUs showed that MAT and annual precipitation significantly explained the observed fungal community structure. These results suggested that climate conditions and site history differentially effect structure fungal communities in pine logs among different ecological groups.
