🍄Mushroom/toadstool query🍄

Fiona from Henderson

My random query is thus, has anyone else who lives in the vicinity of housing developments experiencing a very heavy load of mushrooms or toadstools or other forms of fungi appearing in their garden, potted plants etc ...?
This may sound kind of random, but it seems to be happening in two places out west that I am aware of.
I ask as I have NEVER had any fungi appearing before this last year.
They have suddenly appeared since we've had a couple of large housing developments in the area.
With all of the soil clearance and scrapping of the remaining land preparing for the foundations, I was wondering if any spores of these said fungi have been dug up and are being blown all around the neighbourhood?
I thought that I may have been way off base, and could still be, but a friend who lives in the Swanson area has been experiencing the exact same thing and he has housing developments right across the road and quite a few down Swanson Road.
He seems to agree with my theory and I was wondering if anyone else is experiencing the same thing.
I wonder what else the excavating has loosened and is being transported around the neighbourhood by the wind and all of those heavy trucks removing all the rubble and dirt?
What happened to the LTSA rules for trucks having to cover their loads, especially with loose rubble, dirt, stones etc ...?
