Most importantly - live instruction for the region you are in. Many asian foragers get into distress in the UK due to similar looking but different funghi.
This is one of the most important things for people to remember, to not be confident that their knowledge from one place transfers.
I grew up in Norway and now live in the UK. I haven't been foraging since I moved to the UK and despite the similar climate I wouldn't even do that here without first getting either instruction or at least reading a good field guide over what is actually safe to pick here... I'm guessing it's probably mostly the same ones to look out for, but no way I'd take that risk without triple-checking.
