I’m not an expert in the bio/chem side or really anything to do with mushrooms/fungi, but some families of mushrooms have commonly associated toxins. None of the below should be considered advice or recommendation or relied on in any way.
Amanitas often have a deadly toxin known as Amatoxin, for example.
Some others are sometimes reclassified from toxic to “sort-of-toxic” or “unknown.”
Common mushrooms like Morels can have their toxins cooked out (throw out the cooking water!), while others like Amatoxins will persist.
Still others affect some people, but not others - and some toxins induce negative effects in the presence of other chemicals in the system, like Inky Caps and Alcohol - the combination of which can be deadly, or not, depending on a number of factors.
My understanding of the situation overall is: it’s complicated.
