So, fungal spores are literally everywhere, and the requirements for fungus to thrive seem to be trivially low; give it a moderately humid environment and it’ll grow on a bare concrete wall ffs eating god only knows what; the dust from the air maybe?
Well, and the great outdoors is full of slightly damp places, many of them downright soggy most of the time - and absolutely rife with organic material to snack on.
Where’s the bottleneck? Why isn’t the world a choking fungal hellscape?
The other theory is that mycelium starts to develop in a tree that is about to die, and when the tree falls, that is the trigger for fruiting.
(I personally have no clue where these theories originated from and can’t speak to them.)
