I'm self-taught. I typically learn to collect 1-2 new varieties a year ... but then, I'm foraging for food not new visions. My rule of thumb is that I have to find a mushroom favorably mentioned in at least 3 of the four field guides I carry before I will even bother bringing it home. If there is ANY chance that it might be poisonous or a hallucinogen I make a spore print and study it much closer. By the time I am certain that it is edible, the season for that mushroom is probably over, so I mark the spore print with the positive ID, (Latin + Common names) the date and location collected and the general weather for the week preceding the gathering. This will help me find it again next year by being at the right place at the right time. I have so many bay boletes collected and dried that I didn't bother collecting them this year.
Cut above ground after ascertaining whether there is a bulb at the base (possibly buried) or not. Leave any past their prime to complete their life cycle and toss those that go bad before you can cook them into a similar environment as where you found them, thus "planting" them for future hunts.
