Abstract. Fungi are ubiquitous throughout the near-surface atmosphere, where they represent an important component of primary biological aerosol particles. This study combined the internal transcribed spacer region sequencing and quantitative real-time polymerase chain reaction (qPCR) to investigate the ambient fungi in fine (PM2.5) and submicron (PM1) particles at the summit of Mt. Tai located in the North China Plain, China. The fungal abundance was 9.4 × 104 and 1.3 × 105 copies m−3 in PM2.5 and PM1, respectively. Most of the fungal sequences was from Ascomycota and Basidiomycota which are known to discharge actively spores into the atmosphere. The fungal community showed a significant seasonal shift across different size fraction based on the metastats analysis and kruskal-wallis rank sum test. The abundance of Glomerella and Zasmidium increased and decreased as the particle size got bigger in autumn. Nevertheless, Penicillum, Bullera, and Phaeosphaeria increased in smaller particles in winter. This work may serve as an important reference for the fungal contribution to primary biological aerosol particles.

Short summary
Fungi are ubiquitous throughout the near-surface atmosphere, where they represent an important component of primary biological aerosol particles. The diversity and composition of the fungal communities varied over the different seasons between the fine (PM2.5) and submicron (PM1) particles at the summit of Mt. Tai located in the North China Plain, China. This work may serve as an important reference for the fungal contribution to primary biological aerosol particles.
