Lichenthropy 

A disease that transforms a person into a symbiotic fungus every full moon. It is contracted from rocks that bite. Once a person is afflicted, they can potentially spread it to others via biting.

Once the doctor came to the conclusion that the villagers had been afflicted by lichenthropy, he warned his assistants that werefungi were about.
