Mushrooms are edible and some non-edible
It is cooked as a soup sauce in my country with lovely condiments accompanying it.
I have heard stories (True life) of some folks who died on consumption of Mushrooms.
As great as it maybe most probably as an ideal meal for vegeterians, it is pertinent to be careful on how to distinguish toxic from non-toxic mushroom.

Mushrooms are a sign of healthy soil. In fact, if you pick up a cupful of healthy garden soil, there might be MILES of mycelium strands just within that cupful of soil (no, don’t eat it). These are amazing organisms. Molds and yeasts also belong in this large family or organisms along with mushrooms.

I so agree to this quoted text of yours as presence of Mushrooms validate a soil to be healthy.
How can a toxic and edible mushroom be distinguished?
