No offense, but I read an article about hunting these mushrooms. Here is an excerpt:
"The most important item, however, is your collection bag. Do not use paper or plastic bags, even though they're handy and inexpensive. These bags don't allow mushroom spores to return to their natural habitat. A mesh bag will keep your mushrooms fresh and let those thousands of spores fall back to the ground. The numbers of morels (where they've previously existed) have steadily dwindled over the past 30 years. Deforestation and pesticide use are partial culprits, but the biggest factor has been human beings removing the "seeds" from the woods in nonporous bags. So use mesh and tell other people why it's important."
