The Green-spored Parasol is a widespread, common mushroom that can be found in lawns and fields from summer through fall. It sometimes fruits in fairy rings. It should be noted that this is a poisonous mushroom that is commonly misidentified as an edible species of Macrolepiota, which is generally found in other regions. C. molybdites is the most common source of poisoning in Nebraskans. 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, as seen in the specimen on the left in the following photo.
