Also “sub-”, at least in mycological names.

The other day, I read that there’s a mushroom called “Agaricus subsubensis” and I felt like I was being trolled.

It allows you to keep your arms shoulder-width apart which makes it easier to avoid hunching.

If wish to learn how to forage for mushrooms, join a local mycology club and go out with them. They can identify mushrooms for you and teach you how to do so yourself. They can also recommend good local field guides, I see a few folks in this thread recommending All that the rain promises and More which is a reputable guide but it’s also spectacularly out of date and only applicable to Western North America.

It’s important to know what you’re doing but mushroom identification is not nearly as difficult as some of the comments here make it out to be. There are far fewer deadly mushrooms out there than most people think and it’s fairly easy to familiarize yourself with all the deadly species in your area so you can avoid them.

Nothing wrong with picking a mushroom to ID at home or at an ID clinic run by your local mycology club. You should individually inspect each specimen as you’re cleaning them anyway so you can throw out any which might be going bad, chock full of bugs, or misidentified.

When in doubt, throw it out.

Once again the internet conflates “introvert” with “crippling social anxiety/executive dysfunction”.
