The poisonous Chlorophyllum molybdites closely resembles the choice edible Lepiota and Chlorophyllum species but it does not bruise distinctly yellow or orange or saffron and in age its gills turn greenish. Mature specimens of Chlorophyllum molybdites yield a green spore print, though young specimens can sometimes still have white spores! Also young caps that yield no spores have fooled some people into thinking they had a Lepiota or an edible Chlorophyllum. Also remember that white spores are readily apparent as a deposit even on white paper - if nothing rubs off the paper, there are no spores present. Sometimes the gills pressing on the paper can leave an imprint and even discolor the paper slightly, but no spore powder will be present and thus no spores. In the warmer, generally humid parts of North America where it grows, Chlorophyllum molybdites causes many cases of very serious gastric distress. Children grazing in yards are frequent victims.
