The Green-spored Parasol (Chlorophyllum molybdites) is a widespread mushroom that can be found in lawns and fields from summer through fall. It sometimes fruits in fairy rings. This is a poisonous mushroom that is commonly misidentified as an edible species of Macrolepiota.

The Green-spored Parasol is the main source of poisoning in Nebraska. Although generally not deadly, it can cause severe gastrointestinal upset along with an uncomfortable hospital visit.

The main separating features of this species are free gills and an olive-green spore print. The gills will be greenish at maturity.

If you or someone you know has been poisoned by consuming wild mushrooms, call 9-1-1 and get the individual medical attention IMMEDIATELY. Afterwards, please report poisonings to the North American Mycological Association to contribute to our understanding of wild mushroom safety.
