真菌孢子可以占空气颗粒物的很大比例，它们可能会影响水文循环和气候，作为云，雾和降水中水滴和冰晶的核。此外，一些真菌是主要的病原体和过敏原。然而，空气中真菌的多样性并不为人所知。通过DNA分析，我们发现粗颗粒物和细颗粒物中各类真菌的相对丰度和季节周期存在明显差异，粗颗粒物中植物病原体较多，可吸入细颗粒物中人类病原体和过敏原较多（
Fungal spores can account for large proportions of air particulate matter, and they may potentially influence the hydrological cycle and climate as nuclei for water droplets and ice crystals in clouds, fog, and precipitation. Moreover, some fungi are major pathogens and allergens. The diversity of airborne fungi is, however, not well-known. By DNA analysis we found pronounced differences in the relative abundance and seasonal cycles of various groups of fungi in coarse and fine particulate matter, with more plant pathogens in the coarse fraction and more human pathogens and allergens in the respirable fine particle fraction (
