Clitocybe dilitata grows in crowded clusters and can also occur in rings. Mistaking the Clitocybe dilitata for either the large meaty Lyophyllum multiceps or the smaller Marasmius oreades can have most unpleasant consequences. It reportedly contains muscarine and can cause gastrointestinal havoc accompanied by PSL symptoms - perspiration, salivation and lacrymation. The Clitocybe genus is yet another large genus with few distinctive members and several species that contain muscarine. The Clitocybe monograph runs to 2 volumes of difficult to separate species whose spore color ranges from white to light pinkish buff. If you find a mushroom that looks like a fairy ring mushroom but has close-spaced decurrent gills, watch out!
