For mushrooms I go into one of several asian grocery stores in my area, Chinese, Japanese, Vietnamese and Korean. All kinds of stuff: Shitakes, forest mushrooms (also called skitakes but closer to button style with cracked looking caps) you can get them large and very small too, a new one I just got that's called "reishi" (looks like strips of rosewood and smells like wood - have not tried it yet), White fungus (looks like a yellow sponge with dry texture a bit like paper - tasty in soup), black fungus (really woodsear mushroom - kind of leathery but with a crunch).
You can also get 2 or 3 types of seaweed, dried shrimps and little fish, oodles of noodles, and various other items I just can't think of right now.
Forgot....will try to add photo of 'shrooms this weekend once I figure out how to add it to the post.
That was easy....
Clockwise from top Left: Forest Mushrooms large and small, White Fungus, Reishi, Black Fungus.
Jim Bailey - Whole Foods? I'll have to check that out - have one just around the corner from my office, never noticed dried veges of any kind in it.
