I'm never been good with amounts/sizes. But that would be 1/6 of an ounce. So yes that does sound like a lot. I thought "half an eighth" (1/16th) was a typical beginning dose. So it would be about double that. Definitely could be intense. What is a "hero dose" anyway?
I've been trying some others recently too because I just like mushrooms. Tried some Maitake (Hen-of-the-wood) this week. A bit lacking in natural flavors imo, but great texture and body for cooking in a bit of olive oil. Been wanting to take a mushroom foraging class for some time. They are very interesting, I agree.
