Abstract Soil fungi are crucial drivers of log decomposition in forest ecosystems, but how soil fungal community composition varies during the process remains poorly understood. We conducted an experiment incubating decaying logs a subalpine coniferous on eastern Qinghai‐Tibet Plateau, China. Five classes Minjiang fir ( Abies faxoniana ) were incubated floor, and diversity communities soils underneath measured using high‐throughput sequencing. A total 4321 operational taxonomic units (OTUs) detected by Illumina NovaSeq sequencing analysis. differed significantly was highest decay III or IV. Basidiomycota Ascomycota dominant phyla regardless classes. Moreover, proportion arbuscular mycorrhiza, wood saprotroph saprotrophs increased decomposition, that ectomycorrhiza decreased. The structure varied greatly with Different favour special groups, implying ecological effects at differing different. Highlights Effects groups guilds relative abundance genera
