It pains me everytime that I go to the supermarket and look at the price of a mushroom today. Living in the Pacific Northwest these tasty morsles are abundant yet the grocery stores have limited selections, or dried stock. I love to cook and especially love wild mushrooms. I would like to begin picking my own, and was wondering if anyone new of books or sources to learn. I know they say to go with an expert, but how did they lear, I would like to be an expert. Thanks.
