Yeah but how hard is it to get a guidebook and figure out if Morels are a safe pick in your area. If you already know morels have look a likes where you are, then don't pick them unless you have put in the time on your own research and feel you know how to make that particular ID.
Especially after I've picked something, it is really easy to move backwards and say "is there uncertainty with what this could be?".
It can seem 'easy' to distinguish when familiar. But if you're coming at it fresh it's quite daunting. And to make your friends sick is a significant faux pas.
Anyway that leaves the "I don't want to do this, and I want a 'good reason' and the death card is a good reason" cause of reluctance. It may be more common that we think.
