Ah. Sorry for misunderstanding you.

But that does make any more sense. Fungi don't produce spores
from mycelium, but only from fruiting bodies, and the spores are
almost always distributed by the wind. So, if the fungi did
sporulate, the spores will be all over the garden anyway - which
is the normal state, and why most of the isolation approaches to
fungal containment are such scientific nonsense.

As far as the mycelium goes, you CAN transfer it like that, but it
is pretty rare for a pathogenic fungus to transfer except more or
less by direct root contact. The chance of it surviving in a
compost heap and then infecting plants is very small indeed - if
he DOES have such a fungal infection, we can expect an epidemic
shortly ....
