Humidity and low pH boost occurrence of Onygenales fungi in soil at global scale

Soils are important reservoirs for potential human pathogens and opportunistic fungi such as the dermatophyte or dimorphic in order Onygenales. In soils, these taxa decomposers but many of them have to cause respiratory skin diseases humans and, some cases, systemic infections. Even so, factors that determine biogeography ecology Onygenales remain largely undocumented. To address this knowledge gap, we surveyed members from topsoil fungal communities at 235 sites across six continents provided a first global atlas. We retrieved 4.3% total sequences (∼420 Onygenales) nine biomes ranging deserts tropical forests. This work advances our on distribution suggests hypothesis wet acid soils support larger proportions fungi, while their richness is constrained by aridity.
