Mulch Problem

[SpudsM15]

Guys, about 2 weeks ago we put down some Black dyed mulch... we did it in the rain.
Now I've got a heck of alot of mushrooms popping up. Small ones alot...

Do you think its a combination of it being so hot and humid and the mulch being in the shade? Also been raining like everyother day...

Or is the mulch contaiminated with something?

mulch is basically rotting wood once applied to the ground, so its to be expected.

Both of you are correct. Right conditions and natural spores doing their job in the environment.
