As I kid I did a lot of mushroom picking, mostly porcini varieties, but many other ones as well. I might have seen these mushrooms, but never picked them as they are totally unknown in Ukraine at least to the people who taught me about mushrooms. And the rule was: You don't pick what you don't know.

And all good work has it rewards, and after a very long time

That is the case with many things in life, you have to put in a lot of good work and then after a long time you get rewards...
