I took a mushroom class at UW over the summer, part of which was creating our own edible-mushroom kits from scratch. My professor made the Reishi mushroom kit and gave it to me at the end of the quarter. Reishi mushrooms are much more common in Asian cultures and used as a daily health elixir, tradition says if you drink Reishi tea every day of your life you will live a longer and healthier life. I haven't made Reshi tea yet, but I will soon! Then there is the kit that I made completely from scratch - starting with a mushoom, isolating individual spores, mating germinated spores, and cultivating the mycellial mass that has gone on the bear many Oyster mushrooms.
