Ganoderma lucidum
This hard, club-like mushroom found growing around stumps and trees is known throughout the world by many different names. In Asian countries and elsewhere, Ganoderma lucidum is believed to be one of those important companions for good health. In Illinois, very expensive little bottles of “Reishi” extract are sold to health food customers who don’t seem to realize this varnish-coated mushroom isn’t exactly rare in Illinois or, for that matter, anywhere else in eastern North America.
