FYI you can actually safely lick all mushrooms that we know off. The bad ones will taste bitter if there's every a confusion between the species. Though if you're really unsure don't risk it.

You apparently have a shitty mushroom guide.

Idk if op meant to fearmonger, but mushrooms are hardly ever toxic and hardly ever fatal.

It is now thought that of the approximately 100,000 known fungi species found worldwide, about 100 of them are poisonous to humans.[14] However, by far the majority of mushroom poisonings are not fatal,[15] and the majority of fatal poisonings are attributable to the Amanita phalloides mushroom

That said, definitely be safe and if you arent sure, dont eat it.

My friend forages for porcini mushrooms out near Tahoe. I thankfully don't like mushrooms, so he's not offended when I decline, but idgaf how good he is at finding them, it only takes 1 fuckup and you're dead. He says there's no mushrooms that look like it and as long as you only look for that one, you'll be fine. Frankly imo mushrooms are nasty as hell even when you get the kind you know won't kill you at the store. I have no desire to risk my life to eat wild fungus.
