In Central Oregon, we have had our fill of lightning caused fires and do not want more predictions of thunderstorms. However, the mythology behind lightning increasing mushroom yields has been tested out in some parts of the world with a bit of success. It has long been said that morels in spring come up after the thunderstorms pass and some Matsutake hunters swear they find more specimens a week or so after a thundershower. These tales were not taken seriously by most of us, but check out these articles on early research that gives these ideas some credence. This gives you good reason to look for trees that have been struck by lightning and mark them on your GPS as possible "honey holes."
