> some Gyromitra species may be more dangerous than true morels.

People have died from eating them; they contain a powerful liver poison. Even claiming they are 'called "morels"' is ridiculous and irresponsible.

> Note that not all compounds are destroyed!

Mushrooms, like all matter, is made of "compounds". Dehydration is typically used to remove the dreaded dihydrogen monoxide!

Despite many people such as you and I yelling at random hippies and hillbillies online, they continue to call everything "morels". Reread my comment again: it is true that people colloquially misname dangerous species. I cannot help this. I can only point this fact out.
