I keep warning Hackernews not to trust fungi, and people downvoted me for it. But I keep getting proved right. Don't trust those spores. They're everywhere: in the trees, in the breeze, even our cheese.

Fungi is way too broad a category to "be suspicious of", there's lots of harmless fungi that are basically ubiquitous. And as you note, lots of it in food, often with supposed benefits.
