Fungi cause the majority of plant diseases, which in turn cause serious economic losses. Sometimes, as in the Great Irish Famine of 1845–1849, fungal diseases of plants, in this case potato blight caused by Phytophthora, result in large-scale human suffering. Fungi are similarly the main cause of economic losses of timber in buildings.

If the fungi and infested debris are not washed from the fingers and fingernails soon enough, the fungi can also infect the skin of the fingers (tinea manuum), and burrow underneath and into the material of the fingernails (tinea unguium ...
