Abstract Little is known about the distribution of fungal communities with soil depth on relatively large scales. In this study, typical paddy soils in three regions (Hailun, Changshu, and Yingtan) from north to south China were selected to investigate the vertical distribution (0-100 cm) of the fungal community by Illumina MiSeq sequencing, and to identify the main factors influencing the fungal community distribution. The results indicated that the structure of the soil fungal community changed significantly with region and soil depth. Soil fungal taxa such as Zygomycota, Glomeromycota, Saccharomycete, Kazachstania, Mortierella, Massariosphaeria, Hypholoma, and Zopfiella were enriched at depths of 0–20 cm, whereas Dothideomycetes, Microbotryomycetes, Tremellomycetes, Sporobolomyces, Cryptococcus, Rhodotorula, Fusarium, and Pyrenochaetopsis had high relative abundances at 80–100 cm. Variance partitioning analysis indicated that the geographic distance contributed more to the fungal community variation than environmental variables on a large scale. In addition, soil total carbon and nitrogen contents were the main environmental factors driving the vertical distribution of the fungal community in paddy soils.
