Some fungii grows on dead material (eg compost).

I don't think there are any grows on both.

Actually, there are many that will, but they rarely cause trouble,
except when the plants are weakened or the condtions are very bad.
An example is botrytis (grey mould), and a human example is
athlete's foot, which normally lives on keratin in the soil.
