I just got this book yesterday and quite at the beginning there is a picture of some mushroom, it says are hon shimeji mushrooms.
I cannot find any reference in the book through the index about where I'd find these. I know I've purchase them (or something that looks extremely similar) before at Food Harbor in Addison, but I haven't found them lately.
Also, I'm puzzled about the name. Food Harbor merely called what I bought "mushrooms, white". They do look exactly like the pictured mushroom.
I'd figure they are likely to be some kind of Asian mushroom since Food Harbor has a decidedly Asian bent.
So far my only success in identifying these mushrooms was thinking they were "Trumpet Royale" which I had once dining out and seemed like the same thing look and taste-wise.
Here's a web page I found with a picture of shimeji's which look nothing like what's in your book:

That same place is also offering a "King Eryngii" which from their picture looks like what's in your book (and I think might possibly be at least related to Trumpet Royales):

In any case, where do you think I can find the mushrooms you pictured on page "1" of your book (right after the acknowledgments). I haven't been able to find these (fresh) since spring, and I've sure been missing them!
Oh, by the way, this looks like a very nice book. I also hope to help you get the names of some more great suburban places for your second edition, I just have to consult with some friends first to not miss much.
